Frequently Asked Questions
Is there a limit on how many images I can compress?
No. Compression runs on your own device, so you can compress as many images as you like, with no daily limit.
Which format gives the smallest file?
WebP files are usually 25% to 35% smaller than JPG at the same visible quality. Use JPG when a website or form does not accept WebP.
Will my photo look worse?
At the default quality most people cannot see a difference. If you notice blur, raise the quality slider and apply again.
