Choosing a format

PNG — lossless, supports transparency, large files

PNG preserves every pixel and the alpha channel. Best for logos, UI assets, and screenshots where a pixel-perfect source matters. Downside: files can be 5–15× larger than a visually equivalent JPG.

JPG — smallest files for photos, no transparency

JPG uses lossy compression tuned for photographic content, reaching 10:1 to 20:1 ratios with no visible loss at default quality. Doesn't support transparency. The universal fallback every tool accepts.

WebP — 25–35% smaller than JPG, broad support

Modern lossy + lossless format from Google. Supported in every major browser since 2018. Preserves transparency. The best default for the web.

AVIF — next-generation, 40–50% smaller than JPG

Based on the AV1 video codec. Supported in Chrome 85+, Firefox 93+, and Safari 16+. Smallest files at equivalent quality; slower to encode.

Frequently Asked Questions

Are my images really private?

Yes. Every conversion runs inside your browser using WebAssembly. Nothing is uploaded. Nothing is logged. No account required.

How much quality do I lose?

Depends on the pair. Lossy-to-lossy conversions (JPG→WebP, JPG→AVIF, WebP→AVIF) at default settings are visually indistinguishable from the source. Lossless targets like PNG preserve every pixel.

Is it free?

Yes, with no cap on file size, batch count, or watermark. We pay no server costs because nothing uploads.
