GIF Converter

Upload your file — drag in a GIF, MP4, or a sequence of images. A preview card appears with a timeline you can scrub.

Edit and choose a format — open the Edit drawer to set the frame rate (FPS), resize, and compression, trim the start and end on the timeline, and pick the output: GIF, MP4, WebP animation, or APNG.

Convert and download — click Convert; a progress bar tracks the render, then download the finished file.

No. The converter runs entirely in your browser using WebAssembly, so your videos and images are processed on your own device and never uploaded. Nothing is stored once you close the tab. That keeps your files private and avoids slow uploads — the conversion uses your computer's processor instead of a remote server.

Upload an MP4 (or other supported video), trim it to the part you want using the timeline, set the frame rate and size in the Edit drawer, choose GIF as the output, and click Convert. Keeping the clip short and the frame rate moderate produces a smaller, smoother GIF — long clips make very large files.

Yes, and it's often a great idea. MP4 is far smaller than GIF and is what many social platforms actually prefer, even when you "post a GIF". Upload your GIF, choose MP4 as the output, and convert — you'll usually get a dramatically smaller file that plays smoothly and looks better.

Yes. WebP animation gives better quality at a smaller size than GIF and is well supported on the modern web, while APNG keeps full colour and transparency (unlike GIF's 256-colour limit). Pick WebP for web performance or APNG when you need rich colour and an alpha channel, then convert and download.

A few ways, all in the Edit drawer: lower the frame rate (FPS), reduce the dimensions with resize, and increase compression. Trimming the clip to only the frames you need helps most of all. For the web specifically, converting the GIF to MP4 or WebP usually shrinks it far more than optimising the GIF itself.

Yes. The frame rate (FPS) control in the Edit drawer affects how smooth and how fast the animation plays. A higher FPS is smoother but larger; a lower FPS is smaller and can look choppier. Adjust it alongside trimming and resizing to balance smoothness against file size.

You can upload GIFs, MP4 (and WebM) videos, and static image sequences in JPG or PNG. That lets you build a GIF from a set of frames, convert a video clip, or re-process an existing GIF. Add multiple files and convert them as needed.

You can export to GIF, MP4 video, WebP animation, or APNG (Animated PNG). GIF for universal compatibility, MP4 for the smallest social-ready file, WebP for the best quality-to-size on the web, and APNG for full colour with transparency. Choose the target format before converting.

Yes, within each format's limits. GIF supports a single transparent colour (with optional dithering to smooth gradients), while WebP and APNG support full alpha transparency. If keeping a clean transparent background matters, WebP or APNG will preserve it better than GIF, which can show jagged edges.

Because building a GIF from video is computationally heavy — the tool has to extract frames, calculate a colour palette, and compress everything, all on your device. High-resolution, long clips take more time and produce larger files. Trimming to a few seconds and lowering the frame rate and dimensions keeps it fast and the file small.

Yes. It runs in your phone's browser with nothing to install, so you can convert and optimise GIFs on Android or iOS. Short clips and small GIFs convert smoothly; very large or long videos are heavier and run faster on a computer, but everyday conversions work on mobile.

Yes, completely free with no account and no limits. You can convert and optimise as many GIFs and videos as you like. Because everything runs locally in your browser, there's no paywall, no queue, and no watermark added to your output.
