Animated WebP to GIF Converter
Animated WebP has become a common format for web animations — it is smaller and higher quality than GIF. But lots of older viewers, chat clients, and CMSes still only accept GIFs. This tool converts an animated WebP back into a classic animated GIF that works everywhere, entirely in your browser.
How it works
The browser's ImageDecoder API decodes each frame of the animated WebP, along with the per-frame duration. Each frame is quantized to a GIF-friendly palette (GIF supports up to 256 colors per frame) and written into a new GIF stream with the original frame timing. The result is an animated GIF whose animation matches the source WebP.
When to use GIF over WebP
- Chat platforms — iMessage, legacy Teams, certain Slack setups still prefer GIF.
- Email — Outlook and many corporate email gateways don't render animated WebP.
- Embedded in PDFs or slides — PowerPoint and Keynote handle GIFs natively; WebP often breaks.
- Legacy CMS — older Wordpress themes and static site generators sometimes strip WebP.
- Reaction packs — many meme libraries standardize on GIF.
Palette size control
The colors slider sets the max palette per frame:
- 256 (default) — highest quality, largest files.
- 128 — good balance for most animations.
- 64 — noticeably smaller file, works well for flat illustrations.
- 32 or below — posterized look; only for special effects.
What is preserved
- All frames — no frames are skipped.
- Per-frame timing — GIF delay is set from the WebP frame duration, so playback speed matches.
- Transparency — GIF supports 1-bit transparency; fully transparent pixels are preserved.
What changes
- Colour fidelity — GIF's per-frame 256 colour palette means gradients and photography lose some quality. For flat graphics and emoji-style content, the loss is imperceptible.
- Alpha blending — GIF cannot encode semi-transparent pixels. Partial transparency becomes either fully transparent or fully opaque.
- File size — a GIF is usually 2–5× larger than the source animated WebP at equivalent quality. That is the price of broad compatibility.
Browser support
This tool uses the ImageDecoder API, currently supported in Chromium browsers (Chrome, Edge, Opera, Brave). Firefox and Safari do not yet expose it; on those browsers the tool will show a notice.
Privacy
Everything runs in your browser. Your WebP never leaves your machine.
