Colorize Old Black-and-White Video
AI-driven black-and-white to color video conversion that runs right in your browser. The neural network paints natural skin tones, sky, foliage, and fabrics — pair it with film-stock presets to match the era of the original footage.
How to colorize a black-and-white video
Upload your black-and-white video — MP4, WebM, MOV, AVI, MKV, or M4V
Pick a quality preset (Fast, Standard, or High) and an optional film-stock look
Check the colours on the live preview or run "Preview 5 seconds"
Tweak skin tone or drop a reference image to bias colors, then export
Download as MP4, WebM, GIF, or a ZIP of PNG frames
Restore color to vintage footage with a neural network
Show original video

What this colorizer does
Why use this colorizer
AI video colorizers typically run behind a queue and watermark the output. This one runs right in your browser: the model loads once and works offline thereafter. No queue, no watermark. Pair it with film-stock LUTs to match the era of your footage and a skin-tone slider to fix the typical AI-colorization "zombie face" look.
Frequently Asked Questions
Where does the AI actually run?
In your browser. The colorization model (~55 MB for Standard, ~110 MB for High quality) is downloaded once and cached — it works offline afterwards. On devices with hardware acceleration the neural network runs faster; a fallback mode is used elsewhere.
How long can the input video be?
There's no hard limit, but processing time scales with frame count. A 30-second 720p clip takes about 2-5 minutes on Standard quality with hardware acceleration. For longer videos a confirmation appears when the estimated time exceeds an hour. You can switch to other tabs while it runs — just do not close this one.
Is the original audio preserved?
Yes — the audio track is copied unchanged into the MP4 and WebM outputs. GIF and the PNG-frame ZIP have no audio container, so audio is dropped automatically for those formats.
Does it work on mobile?
Yes. The Fast quality preset is auto-suggested on phones because mobile chips run the neural network significantly slower. For long clips on mobile, expect 5-10× the runtime of a desktop computer.
Which input video formats work?
MP4, WebM, MOV, MKV, AVI, M4V, 3GP, and OGV. If your file isn't recognized, try the Video Repair tool first — corrupted headers and trailing-mdat MP4s often need rebuilding before any tool can read them.
Can I use the colorized result commercially?
The colorization model is published under the Apache 2.0 license, which permits commercial use of its outputs. The tool itself adds no watermark. If your source footage is copyrighted, the original copyright still governs how you can use the colorized version.
