GIF to WEBP

Use PolyImg’s online GIF to WEBP converter to compress, recolor, and preserve transparency with WebCodecs, OffscreenCanvas, and WebAssembly—no uploads, no queues, ideal for ecommerce GIF banners, product tours, and marketing emails.

Capabilities

Smaller payloads, faster pages

Instant transcode

WebCodecs and OffscreenCanvas decode every GIF frame directly in the browser, then re-encode to lean WEBP—even for multi‑MB animations.

Quality controls

Tune lossy/lossless mode, trim frame rates, and edit loop counts while previewing file size and fidelity side by side.

100% local

All pixel operations stay inside the user’s browser, so sensitive launch assets never leave your device.

Everything runs on local CPU/GPU cycles, so there is zero wait time for remote queues or quotas.
Workflow

Three steps to GIF → WEBP

  1. 1Upload or drop one or more GIF files—frames are parsed instantly in the browser.
  2. 2Adjust quality, choose lossy or lossless encoding, and trim redundant frames.
  3. 3Preview the WEBP animation, confirm size and fidelity, then download every export in one click.
  • Set target file sizes, max dimensions, and loop counts while watching the live preview respond instantly.
  • Save multiple export presets per GIF in IndexedDB so recurring marketing assets stay consistent.
Quality & privacy

Pixel-perfect results without a trust trade-off

The converter auto-detects transparency, palette depth, and frame deltas; enable adaptive dithering to retain the character of the original GIF while slicing megabytes off the payload.

Processing happens entirely in browser memory, so neither the input nor the output ever touches a remote server—ideal for unreleased designs or confidential campaigns.
