Frequently asked questions

How much can images be compressed?

Phone photos usually shrink by 60–90% at 70% quality. PNG screenshots shrink 50–80% with colour reduction. Converting to WebP saves a further 25–35% compared with JPG.

Will compression reduce quality?

JPG and WebP compression is lossy, but at 70–80% quality the difference is hard to see. Use the quality slider and compare the result before downloading.

Why did my PNG get bigger?

Canvas re-encoding can enlarge already optimised files. The tool keeps your original when compression would make it larger, unless you untick that option.

Are my photos uploaded to a server?

No. The image is processed by your own browser. It never leaves your phone or computer, so it is safe for ID photos and personal pictures.
