Technical details

Honest browser image compression

JPEG and WebP support adjustable lossy quality through the browser encoder. PNG is re-encoded losslessly because Canvas does not expose a comparable PNG quality setting, so a smaller PNG is not guaranteed.

Helpful answers

Frequently asked questions

Is my image uploaded?

No. This converter decodes and encodes the image inside your browser, so the source and result stay on your device.

Why can a compressed result be larger?

Re-encoding efficiency depends on the source and browser. Filr reports the measured result honestly instead of assuming savings.

Does quality equal file-size reduction?

No. Quality controls encoder tradeoffs, not a guaranteed percentage reduction.

What happens to camera metadata?

Browser Canvas re-encoding typically omits common embedded camera metadata, but behavior can vary by browser.
