Questions & answers
How much smaller will my images get?
Photos often shrink by 60–90%, especially from phones and cameras.
Can I compress many images at once?
Yes. Add as many as you like and download them all as one ZIP file.
Why did my PNG become WebP?
“Auto” turns PNGs into WebP, which is much smaller and keeps transparency. Pick PNG if you need that format.
Is it really free?
Yes. Every Kindkit tool is free with no limits, no watermarks and no sign-up. There is no paid version.
