Frequently asked questions
Will compressing hurt quality?
Lowering quality trades a little detail for a much smaller file. Around 70-80% usually looks identical.
Which format compresses best?
WebP typically gives the smallest files, followed by JPG. Try converting as well.
Are images sent to a server?
No — compression runs entirely in your browser.
