Frequently asked questions
How much can I reduce the file size?
Photos usually shrink by 40–80% at 70% quality with little visible difference. Converting to WEBP often saves even more.
Why did my PNG not get smaller?
PNG is lossless, so re-saving it rarely helps. If a file would get bigger, we keep your original. Choose JPG or WEBP output to compress PNG photos.
Are my images uploaded?
No. Compression happens entirely in your browser, so your images never leave your device.
