Frequently asked questions
Can I compress an image to a specific size?
Yes — choose "Target size", enter a value in KB, and the tool finds the highest quality that stays under it.
Does it reduce quality?
Compression is lossy for JPG and WebP, but at 60–80% quality the difference is usually invisible while the file gets much smaller.
Are my images uploaded?
No — compression happens locally in your browser using a canvas, so nothing leaves your device.
