In-depth guide

Image format converter — PNG, JPEG, WebP, AVIF

Convert images between PNG, JPEG, WebP and AVIF in your browser. Useful for shrinking old JPEGs to WebP, rasterising an SVG to PNG, or migrating a folder of PNGs to AVIF for production. Decodes anything your browser displays, re-encodes via canvas.

Which to pick

  • Need transparency + small file → WebP (universal) or AVIF (smaller but spottier support).
  • Photograph for web → WebP at quality 80.
  • Pixel-perfect graphic → PNG.
  • Email attachment → JPEG quality 70 (best universal support; small).
  • Archive → keep PNG or original.

Browser support notes

  • WebP — universal since 2020 (Chrome, Firefox, Safari, Edge).
  • AVIF decoding — Chrome 85+, Firefox 93+, Safari 16+ (macOS only initially).
  • AVIF encoding via canvas — Chrome / Edge / Firefox 113+ yes; Safari no.
  • If AVIF encoding fails the tool falls back to PNG and shows a warning.

Frequently asked questions

Does this tool upload my image anywhere?

No. The browser decodes the source, redraws on a hidden canvas, and re-encodes locally. The download is a Blob URL.

Which formats can I read in?

Anything your browser can display — PNG, JPEG, WebP, GIF, AVIF, BMP, ICO, SVG. SVG converts to raster on the way out.

Which formats can I output to?

PNG, JPEG and WebP work in every modern browser. AVIF encoding is supported in Chrome 85+, Edge, Firefox 113+. Safari can decode AVIF but as of late 2024 doesn't encode it via canvas.

What's the difference between WebP and AVIF?

Both modern, both replace JPEG / PNG. WebP is universally supported and saves 25-35% vs JPEG. AVIF is newer, often 30-50% smaller than WebP, but encoding support in browsers is uneven.

Does it preserve transparency?

PNG, WebP, AVIF do. JPEG flattens onto a white background (canvas default — chosen over black for visual consistency).

What about ICC profiles and metadata?

Stripped on conversion. If you need colour-managed output, edit in a proper tool. Same for EXIF — use the exif-viewer tool to inspect before converting.
