Video to GIF Converter — Free, No Upload, No Watermark

Q: What video formats can I convert to GIF?

Morph Flowcut supports MP4, MOV, WebM, AVI, MKV, M4V, and FLV as input. Any of these can be converted to an optimized animated GIF directly in your browser.

Q: How do I control GIF file size and quality?

Flowcut uses two-pass palette optimization to produce the best possible color accuracy at the smallest file size. The GIF preset exports at 480px width and 15fps, which balances quality and size. You can also trim your clip shorter to reduce file size further.

Q: Is my video uploaded to a server?

No. All processing happens locally on your device using FFmpeg compiled to WebAssembly. Your video file never leaves your browser. There is no cloud rendering, no server upload, and no data collection.

Q: Does the GIF have a watermark?

No. Morph does not add watermarks to any exports, including GIFs. What you create is what you download — no branding, no logos, no strings attached.

Q: What is two-pass palette optimization?

GIFs are limited to 256 colors per frame. Two-pass encoding first analyzes every frame in your clip to build the optimal 256-color palette, then re-encodes the video using that palette. This produces dramatically better color accuracy and less banding compared to single-pass converters.

What it actually does

01

PALETTE

Two-pass palettegen + paletteuse with Bayer dithering.

Pass one analyzes every frame in the trim window to build the optimal 256-color palette for your specific clip. Pass two re-encodes using that palette with Bayer dithering applied. The same FFmpeg pipeline professional GIF makers run by hand — automated and running in your browser.

02

TRIM

In/out before export

GIFs longer than 8 seconds get huge fast. Flowcut lets you trim the perfect window first.

03

SCALE

Lanczos resampling

480px default with high-quality scaling. Adjustable.

04

SHIP

No watermark

Your GIF, your file. Nothing branded. Nothing logged.

How it works

Open morph.cool/video-editor in any modern browser.
Drop your video. MP4, MOV, WebM, AVI, MKV — all supported.
Trim to the loop window. Most great GIFs land between 2 and 8 seconds.
Select GIF export. 480px / 15fps default with two-pass palette enabled.
Export. The optimized GIF saves to your machine.

Why two-pass matters

GIFs are stuck with 256 colors per frame — a constraint from 1987 that hasn't gone away. Single-pass converters pick a generic 256-color palette and shove every frame through it. The result: banding in skin tones, gradients that look like Mario clouds, and file sizes inflated by trying to compress mismatched colors. Two-pass works the other way around: pass one inspects every frame in your specific clip and builds the optimal 256-color palette for that footage; pass two re-encodes using only those colors. Bayer dithering smooths the remaining gradient transitions. Flowcut runs this entire pipeline locally via FFmpeg.wasm — the same tool professional GIF makers script by hand, automated.

Frequently asked

What video formats can I convert to GIF?

MP4, MOV, WebM, AVI, MKV, M4V, FLV. Any common video container.

How do I control GIF file size and quality?

Two-pass palette delivers the best color in the smallest file. The 480px / 15fps default balances quality and size. Trim shorter to shrink further.

Is my video uploaded to a server?

No. FFmpeg compiled to WebAssembly runs in your browser. Files never leave your tab.

Does the GIF have a watermark?

No. Nothing branded, nothing logged.

What is two-pass palette optimization?

Pass one analyzes every frame to build the optimal 256-color palette. Pass two re-encodes with that palette plus Bayer dithering. Dramatic quality improvement vs single-pass.
