Questions fréquentes

Compresser à 20KB réduit-il la qualité de l'image ?

Lossy compression (like JPEG) discards some image data, but at high quality settings the visual difference is usually imperceptible. Our tool helps you find the optimal balance between file size and quality.

Que signifie compresser à 20KB ?

Compressing to a target size means adjusting the image quality and encoding parameters so the final output file does not exceed the target. Our tool uses a binary search algorithm to automatically find the highest quality setting that meets this limit.

Puis-je compresser plusieurs images à 20KB à la fois ?

Yes! Upload multiple images and compress them all to under 20KB with consistent settings in one batch.
