Frequently Asked Questions

Are my images uploaded to a server?

No. All compression happens inside your browser using the HTML5 Canvas API. Your images never leave your device.

What's the best quality setting?

For most web use, 75–85% gives the best balance between file size and visual quality. If you need a specific size, use the "Target File Size" option.

Why is WebP smaller than JPG?

WebP is a modern format that uses better compression algorithms. It typically produces 25–35% smaller files than JPG at the same quality.

Does compressing reduce image dimensions?

No, unless you set a "Max Width". Compression only reduces file size by re-encoding, without changing pixel dimensions.

Is there a file size limit?

No hard limit, but browsers handle files up to ~50 MB comfortably. For very large images, compression may take a few seconds.
