Are my images uploaded to a server?

No. ImagePal compresses every image directly in your browser using modern Web APIs. Your files never leave your device.

Which image formats can I compress?

JPEG, PNG, and WebP. For best results on photos, use JPEG; for graphics with transparency, use PNG or WebP.

How much can I shrink a file?

Most JPEG and PNG photos compress by 40–80% at the default quality setting of 75 with no visible difference.

Does compression reduce image quality?

Yes, slightly — compression is a trade-off between size and fidelity. Our default (75) is a well-balanced sweet spot. Use the live before/after slider to pick the setting you like.

Is there a file size or count limit?

You can compress up to 20 images per session, with each file capped at 50 MB to avoid running into browser memory limits.
