Everything you need from a video-to-GIF tool
Designed for creators, marketers, and developers who need fast, high-quality GIFs without uploading anything.
Files never leave your device
Conversion happens locally in WebAssembly. Your video never touches a server, which makes the tool safe for client work and unreleased footage.
Two-pass palette encoding
Generates a custom color palette from your clip before encoding. Result: roughly 3× smaller files than naive conversion at the same visual quality.
Trim before you convert
Slide the start and end markers to grab the exact moment you need. Shorter clips mean smaller GIFs that load fast in chats and tweets.
Frame rate and width control
Pick 10, 15, 20, or 24 fps and width 320–640 px (or original). Hit the size and smoothness you need without external tools.
Works offline after first load
The conversion engine caches in your browser, so repeat conversions can run without a network connection in the same session.
Unlimited and free
No daily caps, paid credits, or watermarks. Convert as many videos as you need, as often as you need.
No signup, no watermark
Open the page, drop a video, download the GIF. No account, no email, no branding stamped onto the output.
Works on any modern device
Tested on Chrome, Edge, Safari, and Firefox across desktop and mobile. Larger files do best on desktop where memory is plentiful.
How to convert a video to a GIF
Three steps. No signup, no upload, no watermark.
Drop your video
Drag in an MP4, MOV, WebM, MKV, or AVI file up to 500 MB. The video stays on your device — nothing is uploaded.
Trim and tune
Use the start and end sliders to grab the right moment. Set frame rate and width to balance smoothness against file size.
Download the GIF
A two-pass palette encode runs in your browser. When it is done, save the optimized GIF straight to your device.
Your video never leaves your device
The entire conversion pipeline — decode, palette, paletteuse, GIF encode — runs locally in WebAssembly. Nothing is uploaded, nothing is stored on our side. Open your network tab and check.
What people use it for
GIFs are still the universal embeddable artifact — they autoplay everywhere a video does not.
Chat reactions
Drop a quick reaction GIF into Slack, Discord, or iMessage without sending a heavy MP4.
Marketing & social
Embed product demos in tweets, LinkedIn posts, and email — autoplay GIFs work where MP4 does not.
Bug reports & docs
Show, do not tell. Capture a screen recording, trim it, and paste a small GIF into a GitHub issue or README.
Tutorials & how-tos
Convert a 10-second how-to into a looping GIF that explains a step better than a static screenshot.
Reels & TikTok previews
Turn vertical clips into looping previews for blog posts, newsletters, or pitch decks.
UI animation explainers
Capture a hover or transition you built and share a small, embeddable artifact your team can reference.
Tips for a smaller, sharper GIF
Keep it short
Most great GIFs are under 6 seconds. Each extra second adds frames and bytes — trim aggressively.
15 fps is the sweet spot
Below 15 fps motion looks jerky; above 20 fps file size explodes without much visual gain. Start at 15.
480 px is plenty
For chat embeds, 320–480 px wide looks crisp on every screen. Save 640 px for blog hero images.
Avoid heavy gradients
GIF supports 256 colors per frame. Footage with big sky gradients can band — palettegen helps but cannot fix everything.
Frequently asked questions
Does my video get uploaded to your server?+
No. The entire conversion happens in your browser using WebAssembly (FFmpeg compiled to WASM). Your file never leaves your device, and we do not store anything on our side. You can verify by opening your browser network inspector while you convert.
What video formats can I convert?+
MP4, MOV, WebM, MKV, and AVI work in most modern browsers. If your file is in an exotic codec the browser does not natively decode, the conversion may fail — try re-saving the video as MP4 first.
Is there a watermark on the output GIF?+
No watermark, no branding stamp, no logo. The GIF you preview is exactly the file you download.
Why is the first conversion slower than later ones?+
On the first run the browser downloads roughly 30 MB of FFmpeg WebAssembly assets. They get cached afterwards, so the second and later conversions skip that load and start immediately.
How big can the input video be?+
The tool caps input at 500 MB to keep browser memory predictable. Even within that cap, very large or very long clips can run out of memory on phones — desktop browsers handle the upper end far better.
How do I keep the GIF small?+
Trim aggressively, drop the frame rate to 15 fps, and use 320–480 px width. The tool already runs a two-pass palette encode (palettegen → paletteuse), which roughly cuts size by 3× compared to a naive conversion at the same quality.
Why does my GIF look grainy or banded?+
GIF only supports 256 colors per frame, so footage with smooth gradients (sunsets, gradients, soft skin tones) can show banding. The tool uses Bayer dithering to reduce this; if it still looks rough, try a lower frame rate or a smaller width — both give the encoder more bits per pixel.
Why does my GIF look choppy?+
Choppy motion usually means the frame rate is too low for the action. Bump fps from 15 to 20 or 24 and re-convert. The tradeoff is a larger file size.
Can I make the GIF play once instead of looping?+
Yes. Uncheck "Loop forever" before converting and the GIF will play through once and stop on its last frame.
Does it work on mobile?+
Yes — the tool runs on iOS Safari and Android Chrome. Memory is much tighter on phones, so stick to short clips (under ~30 seconds) or moderate file sizes (under ~100 MB) for the best results.
Can I trim a specific section of the video?+
Yes. The start and end sliders let you pick the exact range you want. Only that segment gets encoded into the GIF.
Why convert video to GIF instead of just sharing the MP4?+
GIFs autoplay and loop in places where embedded video does not — Twitter/X timelines, LinkedIn posts, GitHub issues, README files, email newsletters, Slack and Discord chat. They are the lowest-friction way to show motion in text-first contexts.
Very large files can run out of memory in the browser. If a 400+ MB video fails, trim it with our video compressor first or use a desktop browser with more RAM.
