WebCodecs for hardware H.264 / H.265 / AV1. WebGPU for real-time grading. File System Access for chunked streaming with no upper file-size limit on Pro + Media.
WebCodecs taps NVENC, Apple VideoToolbox, Intel QSV, and AMD AMF. H.265 at ~50% the file size of H.264 with no quality loss.
Pro + Media streams chunks straight to disk via the File System Access API. RAM stays bounded — process 10 GB without crashing the tab.
Every byte stays on your machine. The same engine the AI noise-reducer and image background-remover use, now extended to video.
Auto-reframe, subtitle burn-in, GIF/WebP export, and thumbnail capture for short-form video
Hard-burn captions into the video frame so they show on every player — TikTok, Instagram, X, and Reels. Style fonts, position, and colour locally.
Open toolTwo-pass palette generation produces GIFs that look as good as the source. Pick frame rate, width, and looping behaviour locally.
Open toolAnimated WebP is roughly 30% smaller than the equivalent GIF, supports alpha, and plays in every modern browser. Convert locally without uploading.
Open toolSmart-centred crop from 16:9 to 9:16 (vertical) or 1:1 (square). Pan-and-scan logic keeps the action in frame for short-form social.
Open tool9:16 vertical, 60-second cap, encoded at the YouTube-recommended bitrate. One click to ship a Shorts-ready file.
Open toolSquare 1:1 or vertical 4:5 — the two highest-engagement IG feed formats. Encoded at the platform-recommended bitrate ceiling.
Open tool16:9 horizontal, 2:20 max length, H.264 + AAC at the bitrate X transcodes from. Avoids X's heavy re-encode for higher visible quality.
Open toolHardware-accelerated H.265/AV1, Discord/email size targets, and bitrate control
Auto-target Discord's free 25 MB upload cap or Nitro's 50 MB cap. JAD computes the bitrate, encodes locally, and lands within ±2% of the target.
Open toolHit Gmail's 25 MB and Outlook's 20 MB attachment caps. Local processing — your video never leaves your machine.
Open toolShrink any clip to fit WhatsApp's 16 MB chat / status limit without WhatsApp's heavy re-compression that kills quality.
Open toolHardware-accelerated H.265 encoding via WebCodecs (NVENC, VideoToolbox, AMF, QuickSync). Roughly half the bitrate of H.264 at the same quality.
Open toolHardware AV1 encoding via WebCodecs on RTX 40-series, Apple M3+, and Intel Arc. ~30% smaller than H.265 at the same quality.
Open toolRe-encode to an exact video and audio bitrate. Useful for streaming presets, upload caps, and matching delivery specs.
Open toolRe-encode to 720p H.264 with +faststart so the moov atom lives at the start of the file — videos play instantly without waiting for the full download.
Open toolMP4, MOV, MKV, WebM, AVI, ProRes, and AV1 transcoding — all local
Convert between MP4, MOV, MKV, WebM, AVI, M4V, TS, and ProRes locally. Hardware-accelerated H.264/H.265/AV1 when available.
Open toolGenerate ProRes 422, 422 HQ, and 4444 files for Final Cut, Premiere, and DaVinci Resolve. Local — never uploads your footage.
Open toolFix sideways or upside-down recordings without re-encoding when possible. Lossless rotation via metadata, with a re-encode fallback for unsupported containers.
Open toolMirror your video across either axis. Useful for selfie footage, reaction videos, and matching shot orientations during edits.
Open toolCut out the bars, the corner overlay, or the bystander. Custom rectangle crop with pixel-precise dimensions and offset.
Open toolLanczos-scaled resize with optional aspect-ratio lock. Hit a specific output resolution for upload caps, embeds, or social-platform specs.
Open toolConvert interlaced 1080i, 480i, or DV footage to progressive 1080p / 480p using FFmpeg's yadif filter. Removes combing artefacts.
Open toolLossless trim, merge 4K clips, watermark overlay, and speed control
Cut MP4, MOV, MKV, and WebM files without quality loss. Stream-copy mode keeps original codec, original quality, and finishes in seconds.
Open toolConcatenate MP4, MOV, MKV, and WebM clips locally. Same-codec inputs use stream-copy for instant lossless joining; mixed-codec inputs are re-encoded.
Open toolAdjust playback speed from 0.25× to 4× with audio time-stretching to preserve pitch. Hardware re-encoding for smooth output.
Open toolBurn a PNG or SVG watermark into any video. Pick position, opacity, and scale. WebGPU compositor for real-time preview.
Open toolBrightness, contrast, saturation, and tone curves rendered on the GPU at 4K. Export the graded result via hardware encoding.
Open toolCut a long video into N equal segments, or chunks of a fixed duration. Stream-copy mode keeps quality identical to the source.
Open toolPlay a clip backwards — perfect for boomerangs, transition reveals, and meme reactions. Audio is also reversed and time-aligned.
Open toolTwo-pass vidstab analyses motion vectors then warps each frame to compensate. Removes camera shake from handheld and action-cam clips.
Open toolStrip metadata, blur faces, and redact regions before sharing
Remove GPS coordinates, camera make/model, recording dates, and software identifiers from MP4, MOV, MKV, and WebM. Lossless — never re-encodes.
Open toolAI face detection runs locally via TensorFlow.js BlazeFace. Blurs every face across every frame with no upload.
Open toolDraw a rectangle, set the time range, and JAD blurs that region for the duration. Use for redacting names, plates, screen content.
Open toolAI face detection with a mosaic / pixelate effect instead of Gaussian blur. The 'TV news anonymisation' look — local, no upload.
Open toolSilence a section of the audio without touching the video. Useful for bleeping out names, slurs, or accidental brand mentions.
Open toolPull frames, audio tracks, subtitles, and chapters from any video
Pull JPG or PNG thumbnails at fixed intervals (every 1s, 5s, 10s) or at evenly-spaced positions. Returns a ZIP of frames.
Open toolPull the audio out of MP4, MOV, MKV, WebM, and AVI files. Stream-copy preserves the original AAC/Opus/MP3 quality.
Open toolPull subtitle tracks out of MKV, MP4, and MOV files. Returns each track as a separate .srt file.
Open toolPull chapter markers from MKV / MP4 files into structured JSON. Useful for auto-generating timestamps in podcast notes.
Open toolAuto-detect hard cuts using FFmpeg's scene-change detection. Returns a JSON timeline of cut timestamps for highlighting reels.
Open toolBuild a single PNG contact sheet showing N evenly-spaced frames in a grid. Perfect for storyboards, scene reviews, and YouTube chapter art.
Open toolRoadmap
All 40 tools across the 6 sectors are live. Pro + Media tools stream output directly to disk via the File System Access API — no upper file-size limit. Real-time WebGPU colour-grading preview, streaming pipeline, and batch processing (up to 25 files on Media) are all shipped. Per-tool spoke pSEO build-out ships in a subsequent pass.
