Picking the right format
What each one is best at.
- PNG — lossless. Best for logos, screenshots, diagrams, anything with sharp edges or transparency. Larger files than JPG/WebP for photos.
- JPG— lossy, no transparency, universally supported. Best for photos where small artefacts won't matter. The default for photography for the last 30 years for good reason.
- WebP — lossy or lossless, supports transparency, typically 25–35% smaller than JPG at equivalent quality. The right default for the web in 2026 unless you need to email a file to someone on a 10-year-old viewer.

Common workflows
- Shrink a PNG for the web. Convert to WebP at quality 85 — typically halves the size with no visible difference.
- Email a photo. Convert a giant PNG screenshot to JPG at quality 80 to slip under mail-server attachment limits.
- Future-proof a logo. Keep the original PNG, export a WebP for modern browsers, and let your
<picture>tag pick the right one per visitor.
Frequently asked
Which formats can I convert between?
Input: PNG, JPG, WebP, AVIF, GIF, BMP, and any format your browser can decode. Output: PNG, JPG, and WebP — the three with universal browser support. AVIF output isn't enabled because Safari can't encode it client-side as of 2026.
Will I lose quality?
PNG output is lossless. JPG and WebP are lossy — adjust the quality slider to trade size for fidelity. At quality 85, most images are visually indistinguishable from the original at roughly half the size.
Is anything uploaded?
No. Decoding and encoding both happen in your browser via the canvas API. The image, the intermediate pixel buffer, and the output blob never leave your device.
