Frequently Asked Questions

Common questions about image compression and formats

Is this online image compressor free to use?

Yes. Our tool is free with no registration, usage limits, or watermarks.

How does image compression work?

JPEG, WebP, and AVIF compression removes subtle, imperceptible color variations and strips unnecessary metadata. PNG compression applies lossless filtering to pack color tables efficiently.

Are my pictures uploaded to a remote server?

No. All compression algorithms run locally in your browser using modern WebAssembly and Canvas technologies. Your photos never leave your device.

Which output format gives the smallest file size?

WebP and AVIF typically provide 25% to 50% smaller files than JPEG at equivalent visual quality. PNG is best suited for graphics and screenshots requiring sharp text and transparency.
