All processing happens in your browser. No data is sent to any server.

Animated WebP exists, but a browser canvas cannot write it, so be clear about what this page does: it takes the frame your browser renders from the GIF and encodes that single picture as a lossy still WebP. Within that limit the swap is a good one: WebP is not capped at 256 colours, it carries a real alpha channel rather than one transparent palette slot, and it beats LZW badly on photographic material.

Key facts about GIF to WebP converter

Key facts about GIF to WebP converter
Output is a stillOne frame, always. The canvas API offers no animated WebP writer, unlike a command-line tool such as gif2webp.
Colour ceiling removedGIF caps a frame at 256 palette entries. The WebP is written from full RGB canvas data, so later edits are no longer trapped in that palette.
TransparencyPreserved and upgraded. The all-or-nothing transparent index of GIF becomes a true 8-bit alpha channel stored in a separate ALPH chunk.
Compression modeLossy VP8 only. A canvas cannot emit lossless WebP, so the crisp flat colours of GIF art are re-encoded rather than copied.
Quality control30 to 100 in steps of 5, default 90, with an estimated output size that updates as you drag.
Typical size deltaA 500x500 photographic GIF of 300 KB usually drops under 60 KB at quality 90. A small flat-art GIF may not shrink at all.
Animation dataFrame durations, loop counts and disposal flags are consumed by the decoder and have nowhere in a still to go.
Opens the resultChrome, Edge, Firefox, Opera, Safari 14 upward, Windows 10 and 11, macOS Big Sur onward, GIMP and Affinity. Some older viewers and email clients will not.

What happens to your file

There is no transfer step to worry about. The GIF is exposed to the page as an object URL, decoded by the browser's own GIF reader inside an Image element, and drawn onto a canvas belonging to this tab. Requesting image/webp from canvas.toBlob invokes the WebP encoder that ships with your browser, on your processor. Nothing is posted anywhere, because there is no remote server involved in the conversion at all.

About this tool

  1. 1

    Choose your GIFs

    Drop up to twenty .gif files on the target area, or click to pick them. The ceiling is 500 MB per file.

  2. 2

    Confirm the frame

    The preview shows the captured frame over a checkerboard. What you see there is what gets encoded.

  3. 3

    Tune the quality

    Default 90 is a safe start. Because the source had at most 256 colours, dropping to 70 is often indistinguishable.

  4. 4

    Convert and download

    Press Convert, then save the WebP or take converted-webp-files.zip, which is assembled locally.

Specs & compatibility
Input and outputTakes .gif only (image/gif) and returns .webp with the image/webp type; any other extension is refused before decoding.
Conversion pathGIF to WEBP runs in three steps: an <img> element decodes the GIF and only its first frame reaches the canvas; the pixels land on a 2D canvas in this tab; then canvas.toBlob with the image/webp type returns the finished file.
Browser supportThe GIF side decodes in every browser ever shipped, while writing the WebP works in Chromium browsers and Firefox, and where the type is unsupported the canvas specification makes the browser return PNG bytes under the .webp name.
Controls for this pairA 30 to 100 quality slider (steps of five, default 90) drives the WEBP encode, max-dimension presets from 3840 down to 200 px resize the GIF first, and the strip-metadata toggle is moot on this pair.
Batch, caps and namingTwenty GIF files per run at 500 MB each; one result downloads as a single WEBP, several as converted-webp-files.zip, zipped by JSZip 3.10 in page memory.
Device ceilingThe canvas caps it: past roughly 16,384 px a side Chromium refuses the bitmap and iPhone Safari gives up sooner, so an oversized GIF fails before any WEBP bytes exist.
  • Serve the WebP with a GIF fallback if your audience includes older email clients, where support lags browsers by years.
  • If the WebP comes out bigger than the GIF, the source was flat art with few colours, the one case the old format wins.
  • Use this to build the poster image for a video that replaces a heavy animated GIF.
  • Hard palette edges can fringe at low quality because VP8 subsamples chroma, so stay at 80 or above for line art.
  • Single-frame WebP with a real alpha channel
  • Adjustable VP8 quality with a size preview
  • Seven pre-encode resize presets
  • Twenty GIFs per run, ZIP built in the tab
  • Replacing static GIF decorations on a site with a format that is smaller and not stuck at 256 colours.
  • Creating a lightweight poster frame for an animation that will be delivered as video.
  • Modernising a folder of legacy GIF assets ahead of a site rebuild.
Not here. Animated WebP is real and well supported, but the only encoder a page can reach is behind canvas.toBlob, which writes a single still image. Producing animated WebP requires reading every frame and muxing them, which gif2webp or a WebAssembly build of libwebp does. This page gives you the first frame.
No. For a photographic or gradient-heavy GIF the saving is often eighty percent or more, because LZW over a 256-colour palette suits that material badly. For a small flat-art GIF, a logo or a two-colour icon, LZW is extremely efficient and lossy VP8 may produce a similar or larger file.
Yes. GIF stores transparency as one designated palette index, which the browser turns into fully transparent pixels while decoding, and WebP has a proper alpha channel to receive it. Edge quality does not improve, since the source only ever had on or off transparency, but nothing further is lost.
Because canvas.toBlob exposes only the lossy WebP path. The format does define a lossless mode that would suit flat GIF art perfectly, but no browser API can request it. For pixel-exact output from a GIF frame, convert to PNG, which the canvas does write losslessly.
No. Quality 100 tells the encoder to spend the maximum bit budget, not to skip the transform. Flat colour areas can shift by a value or two and chroma is still subsampled. Visually it is indistinguishable, but a pixel comparison against the GIF frame will show differences.
