Shows the measured values before and after, with a player and a download.\n\nMethodology:\n- Pass 1 measures the file with ffmpeg's loudnorm filter (ITU-R BS.1770 / EBU R 128 meter): integrated loudness (LUFS), true peak (dBTP, oversampled), loudness range (LRA) and the gating threshold.\n- Pass 2 feeds the measured values back into loudnorm with linear=true: if the whole file can reach the target with one gain change without exceeding the true-peak limit, only the gain changes (linear). Otherwise loudnorm switches to dynamic mode, which compresses and limits — the result reports which one happened.\n- loudnorm works at 192 kHz internally; the output is resampled back to the original sample rate. The podcast-mono preset also mixes to mono.\n- Pass 3 measures the finished file again, so the \"after\" values are real measurements of the download, not the targets (for files over 15 minutes the normaliser's own output report is used instead, to stay within the time limit). Files up to 45 minutes are accepted.\n- Spotify (−14 LUFS, true peak below −1 dB) and EBU R 128 (−23 LUFS) are published targets; YouTube ≈ −14 and Apple ≈ −16 LUFS are widely used measured/recommended values, not contractual specs. Podcast −16 LUFS stereo / −19 LUFS mono are common industry recommendations.\n\nVery short files (under about 3 seconds) give less reliable integrated loudness, because the meter gates in 400 ms blocks.", "tags": [ "media" ], "x-mcp-tool": "audio_loudness_normalizer", "requestBody": { "required": true, "content": { "application/json": { "schema": { "$ref": "#/components/schemas/AudioLoudnessNormalizerInput" }, "examples": { "example1": { "summary": "Normalise a test tone to the Spotify target", "value": { "file": { "filename": "tone.mp3", "contentType": "audio/mpeg", "contentBase64": "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" }, "preset": "spotify", "format": "wav" } } } } } }, "responses": { "200": { "description": "Calculation result envelope.", "content": { "application/json": { "schema": { "$ref": "#/components/schemas/AudioLoudnessNormalizerResult" } } } }, "400": { "description": "Malformed JSON body.", "content": { "application/problem+json": { "schema": { "$ref": "#/components/schemas/Problem" } } } }, "422": { "description": "Invalid input (see errors[]).", "content": { "application/problem+json": { "schema": { "$ref": "#/components/schemas/Problem" } } } }, "429": { "description": "Rate limit exceeded (see Retry-After).", "content": { "application/problem+json": { "schema": { "$ref": "#/components/schemas/Problem" } } } } } } }, "/api/v1/tools/background-remover/calculate": { "post": { "operationId": "calculateBackgroundRemover", "summary": "Remove plain backgrounds from product photos and logos (colour-based, no AI) → transparent PNG.", "description": "Makes the background of an image transparent by colour: it estimates the background colour from the image border and removes it with an adjustable tolerance, or removes one colour everywhere (chroma key / green screen). Works well for product photos, logos and scans on plain backgrounds; it does NOT understand people or complex scenes, because it uses no AI model.\n\nMethodology:\n- This is NOT an AI background remover. It decides per pixel by colour distance only, so it works for a subject on a plain, evenly coloured background (product shots, logos, scans, green screen) and fails on busy scenes, hair, or subjects with the same colour as the background.\n- Automatic mode shrinks the image to 200×200 px and takes the per-channel median of a 3-pixel border ring as the background colour. The share of border pixels within the tolerance (\"border uniformity\") predicts how well the method will work.\n- Edge-connected modes add a 1-pixel frame in the background colour and flood-fill from it with ImageMagick (-fuzz, -floodfill), so only background regions touching the edge are removed and same-coloured areas inside the subject stay. Chroma-key mode removes every pixel close to the colour, wherever it is.\n- The resulting mask is cleaned with a morphological open (removes specks) and close (fills pin holes) using a disk of the chosen radius, optionally blurred to feather the edge, and used as the alpha channel of a PNG.\n- Existing transparency is flattened onto white first.

RAW files are developed with LibRaw (dcraw_emu): demosaicing (AHD), camera or automatic white balance, sRGB output, 8 bits per channel.\n- ImageMagick encodes JPG/PNG; WebP is encoded with libwebp (cwebp) when installed. Width, height and pixel count are checked before decoding (limit 100 megapixels).\n- With \"Keep EXIF\" on, exiftool copies EXIF/XMP/IPTC from the original into the new file (without embedded previews) and resets the Orientation tag when the pixels were rotated. Otherwise the output carries no metadata at all.\n- RAW development here is a neutral default rendering.

For animated GIFs only the first frame is used.\n- ImageMagick decodes the image, applies the EXIF orientation, optionally scales it down (never up) to fit the maximum width/height, and encodes it in the chosen format. AVIF is encoded with libavif (avifenc) when it is installed.\n- Quality is passed to the encoder as is (1–100).

A side-by-side crop compares plain pixel enlargement with the result. This is classic interpolation, not an AI upscaler: it cannot invent detail that is not in the original.\n\nMethodology:\n- Classic (non-AI) upscaling: every new pixel is a weighted average of nearby original pixels. Lanczos, Mitchell and Catmull-Rom are separable windowed filters; \"EWA Lanczos Sharp\" uses a cylindrical (elliptical weighted average) filter that produces fewer staircase artefacts on diagonal edges.\n- Optional noise reduction runs before enlarging (so noise is not magnified): despeckle, enhance or a 3×3 median. Optional unsharp-mask sharpening runs after enlarging to counter the softness that interpolation causes.\n- The image is turned upright from its EXIF orientation, resized in linear light (to avoid darkened edges), converted back to sRGB and encoded. The output is limited to 16 megapixels.\n- What AI upscalers do differently: models such as Real-ESRGAN or SwinIR are neural networks trained on millions of image pairs. They hallucinate plausible texture (hair, foliage, text strokes) that is not in the original. That looks sharper, but it can invent wrong details, alter faces and change text. Classic filters never add information; they only interpolate it, so results look softer but stay faithful.\n\nEnlarging cannot recover detail that was never captured.

Lossless formats ignore the bitrate.\n- Opus only supports 8/12/16/24/48 kHz and MP3 at most 48 kHz; other rates are resampled to the nearest supported rate and you get a warning.\n- Tags are copied with -map_metadata 0; album covers are copied for MP3, M4A and FLAC (Ogg/WAV/AIFF covers are not supported by ffmpeg muxers). Encoder version tags and timestamps are not written, so the same input always gives the same file.\n- ffprobe reads the result again for the before/after report.\n\nConverting a lossy file (MP3, AAC, Ogg) to another lossy format or to a lossless format cannot restore lost quality.", "tags": [ "media" ], "x-mcp-tool": "audio_converter", "requestBody": { "required": true, "content": { "application/json": { "schema": { "$ref": "#/components/schemas/AudioConverterInput" }, "examples": { "example1": { "summary": "MP3 tone to Ogg Opus 64 kbit/s, mono", "value": { "file": { "filename": "tone.mp3", "contentType": "audio/mpeg", "contentBase64": "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" }, "format": "opus", "bitrate": "64", "channels": "1" } }, "example2": { "summary": "MP3 to lossless FLAC with tags", "value": { "file": { "filename": "tone.mp3", "contentType": "audio/mpeg", "contentBase64": "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" }, "format": "flac" } } } } } }, "responses": { "200": { "description": "Calculation result envelope.", "content": { "application/json": { "schema": { "$ref": "#/components/schemas/AudioConverterResult" } } } }, "400": { "description": "Malformed JSON body.", "content": { "application/problem+json": { "schema": { "$ref": "#/components/schemas/Problem" } } } }, "422": { "description": "Invalid input (see errors[]).", "content": { "application/problem+json": { "schema": { "$ref": "#/components/schemas/Problem" } } } }, "429": { "description": "Rate limit exceeded (see Retry-After).", "content": { "application/problem+json": { "schema": { "$ref": "#/components/schemas/Problem" } } } } } } }, "/api/v1/tools/video-converter/calculate": { "post": { "operationId": "calculateVideoConverter", "summary": "Convert video to MP4, WebM, MOV or MKV: resize, set quality and fps, or remux losslessly.", "description": "Converts MP4, MOV, MKV, WebM, AVI and other videos to MP4 (H.264/AAC), WebM (VP9/Opus), MOV or MKV.

Nothing is re-encoded, so quality is identical.\n- Re-encoding uses libx264 (preset veryfast, CRF, High profile, yuv420p) for MP4/MOV/MKV or libvpx-vp9 (constant quality CRF, cpu-used 5, row-mt) for WebM, with -threads 2 on our 2-vCPU server. Scaling keeps the aspect ratio with even dimensions and never enlarges; the frame rate is only ever reduced.\n- Audio is copied when the target container supports the codec, otherwise encoded as AAC 128 kbit/s (MP4/MOV/MKV) or Opus 96 kbit/s (WebM). Subtitles and data tracks are dropped.\n- Before encoding, the work is estimated from output pixels × frames; jobs that would exceed about 220 s of encoding are refused with a suggestion (lower resolution/fps, trim, or remux).", "tags": [ "media" ], "x-mcp-tool": "video_converter", "requestBody": { "required": true, "content": { "application/json": { "schema": { "$ref":

9:16 (Reels, Shorts, TikTok), square 1:1, 4:5 or 16:9.

Output H.264/AAC MP4 at 1080, 720, 540 or 360 px on the short side, with a first-frame preview.\n\nMethodology:\n- The output frame is derived from the aspect ratio and the short side (9:16 at 1080 → 1080×1920). Rotation metadata from phones is applied first.\n- Crop: the video is scaled to cover the frame and a frame-sized window is cut out; the position slides the window from left (0 %) to right (100 %), or top to bottom for sources taller than the frame. The report shows how much of the picture is kept.\n- Blurred background: a copy is scaled to cover the frame, shrunk to a quarter, box-blurred and scaled back up (cheap on CPU); the whole picture is fitted on top, centred.\n- Bars: the picture is fitted inside the frame and padded with black or white bars.\n- All sizes and offsets are computed as numbers in TypeScript before they go into the ffmpeg filtergraph.

quality.", "description": "Compresses a video to a target file size with a two-pass H.264 encode: the bitrate is calculated from the size and length, minus the audio budget, and the resolution is lowered automatically when the bitrate would be too thin. Presets for e-mail (25 MB), WhatsApp (16/100 MB) and Discord (10 MB), or a constant-quality CRF mode. Reports the achieved size.\n\nMethodology:\n- Target size: usable bits = (target − 2 % − 20 kB container overhead) × 8. Total bitrate = usable bits ÷ duration. Audio gets 128/96/64/48/32 kbit/s, at most about 20 % of the total; the rest goes to the video. If the video would get less than 50 kbit/s, the tool tells you the smallest workable target instead.\n- Resolution \"automatic\" picks the largest standard height (never above the source) where the video bitrate still gives at least 0.05 bits per pixel per frame — a common H.264 rule of thumb — and caps the frame rate at 30 fps when the bitrate is below 2 Mbit/s. The suggestion table shows bits per pixel for each step.\n- Two-pass libx264 (preset veryfast): pass 1 analyses the video, pass 2 distributes the bitrate where it is needed, which hits the size much more precisely than one pass. maxrate/bufsize limit spikes. Quality mode is a single CRF pass.\n- The output is MP4 (H.264/AAC, faststart for streaming). The achieved size is measured and compared with the target; two-pass is typically within a few percent.\n\nSize limits of e-mail providers and messengers change; check the current limit of your service.

removes a section from the middle, or joins up to 5 clips in order. Copy mode is fast and lossless but cuts on keyframes; exact mode re-encodes (H.264/AAC) for frame-accurate cuts. Clips with identical settings are joined losslessly with the concat demuxer, others are normalised to a common size and frame rate first.\n\nMethodology:\n- Copy mode (-c copy) never re-encodes, so it is fast and lossless — but a video can only start on a keyframe. ffprobe lists the keyframes, and the tool reports where the cut really starts (the last keyframe at or before your start time). End points are exact to the frame.\n- Exact mode trims with the trim/atrim filters and re-encodes with libx264 (veryfast, CRF 20) and AAC 160 kbit/s, so every cut lands on the requested frame.\n- Remove a section: the parts before and after are kept and joined — by copying both parts and joining them with the concat demuxer (copy mode; the second part starts at a keyframe) or with the concat filter (exact mode).\n- Merge: if all clips share codec, resolution, pixel format, frame rate and audio settings they are joined with the concat demuxer without re-encoding. Otherwise each clip is scaled and padded to the first clip's size (max 1080p), set to its frame rate, given silent audio if it has none, and joined with the concat filter.", "tags": [ "media" ],

Shows the size, frame count and a preview.\n\nMethodology:\n- ffmpeg seeks to the start time and reads up to 15 seconds. The frames are resampled to the chosen fps and scaled with Lanczos to the width (never wider than the source); the height follows the aspect ratio.\n- GIF: palettegen builds an optimal palette of up to 256 colours from the clip (from all pixels or only changing ones), and paletteuse maps every frame to it with the chosen dithering. This is the standard two-stage method for high-quality GIFs.\n- Animated WebP uses libwebp (lossy, quality 1–100), which is typically several times smaller than a GIF of the same clip.\n- All values

Other codecs (e.g. AC-3, DTS) need re-encoding and are refused in copy mode.\n- Trimming seeks to the start time and stops after the requested length.
