Frequently asked questions

Are my images uploaded to a server?

No. Compression happens 100% in your browser. Nothing leaves your device.

Will compression reduce quality?

At 70–80% quality, most people can't tell the difference. Go lower only if size matters more than quality.

What's the best format?

WebP usually gives the smallest size with good quality. JPG is universally supported. PNG is best for images with transparency.

Is there a file size limit?

Browser memory limits us to roughly 20 MB per image. Larger images may fail on low-end phones.
