Your images never leave this tab.
Open your browser's developer tools, switch to the Network tab, and convert a file. You will see the encoder and its WebAssembly module load from this domain the first time, and then nothing — no upload, no image data, no request carrying your file anywhere. Turn off your Wi-Fi after the page loads and it still works.
Most files that are still GIFs today fall into two groups: animations, and things that should have stopped being GIFs twenty years ago.
For the second group — logos, icons, diagrams, old screenshots — WebP is a straightforward win. GIF is capped at a 256-colour palette, so lossless WebP can usually reproduce the image exactly while producing a noticeably smaller file.
For the first group, be aware of the limitation up front: this converter takes the first frame only. The encoder it uses handles still images, not animation. Any animated file you drop is flagged in the list rather than being quietly flattened. If you need to keep motion, convert to MP4 or WebM instead — for real animation, video beats both GIF and WebP by a wide margin.
Frequently asked questions
- Does this keep GIF animation?
- No, and we would rather say so plainly than surprise you. Animated GIFs are converted to their first frame only, and any file where that happens is flagged in the list. Producing animated WebP needs a different build of the encoder than the one this tool uses, and we would rather ship an honest limitation than a silent one.
- Why convert a GIF to WebP at all then?
- Plenty of GIFs are not animated — old logos, icons, diagrams and screenshots are often still GIFs for historical reasons. Those convert beautifully. GIF is limited to a 256-colour palette, so lossless WebP usually reproduces them exactly while being substantially smaller.
- What should I use for animation instead?
- For genuinely animated content, an MP4 or WebM video is almost always the better answer — usually 5-10x smaller than the equivalent GIF and better supported than animated WebP. Most modern sites replace animated GIFs with a muted, looping, autoplaying video.
- Will a GIF's transparency survive?
- Yes. GIF supports single-colour transparency, and WebP's full alpha channel represents that without difficulty. Use lossless mode to keep the edges exactly as they were.
Other conversions
Each converter opens with the right output format already selected, so the file you drop comes back in the format you came for.
Convert WebP to another format
Convert images to WebP
- Convert PNG to WebP Keep the transparency, drop most of the file size. Lossless mode is one click away if you need pixel-exact output.
- Convert JPG to WebP Typically 25-50% smaller than the same photo as a JPEG, at a quality most people cannot tell apart.
- Convert JPEG to WebP The same conversion as JPG — the two extensions are one format. Smaller files, same picture.
- Convert HEIC to WebP iPhone photos, converted in the browser. No app, no upload, and it works on iOS Safari where most converters do not.
- Convert AVIF to WebP Usually a compatibility move rather than a size one. WebP opens in more places than AVIF still does.
- Convert TIFF to WebP Scans and print files, converted to something a browser can actually display.
- Convert BMP to WebP BMP stores pixels essentially uncompressed. Expect the file to get very substantially smaller.
- Convert SVG to WebP Turning vector into pixels. You choose the size, because a vector does not really have one.
