How to use Compress image
By quality or to a target size
“Quality” gives you one slider for the whole batch: 80 is invisible on a screen, 90 is safe for printing. “Target size” takes a number in KB and searches for the highest quality that fits under it, scaling the image down only if quality alone can’t get there. The preview shows one image before and after while you adjust.
The biggest lever is the pixel count
A photo from a modern phone is around 4000 px wide, far more than a screen, a chat app or a website will ever show. Set “longest side at most” to 2000, or 1600 for messaging, and the file often drops by 80% before the quality slider does any work at all.
PNG barely compresses
PNG is lossless, so keeping the format only rewrites the file and the savings stay small; a target size can then be reached only by making the image smaller. If you don’t need the transparent background, choose JPG or WebP as the output format and the same picture becomes a fraction of the size.
Questions
Are my photos uploaded to a server?
No. Everything runs inside your browser, so your photos never leave your device. Close the tab and nothing is left behind.
Will the quality get noticeably worse?
At the default quality of 80 you can hardly tell the difference on a phone or computer screen. For large prints, raise it to 90.
Can PNG be compressed too? Will I lose the transparent background?
Yes. If you keep the PNG format the transparency is preserved, but the savings are limited. If you don’t need transparency, converting to JPG or WebP gives a much smaller file.
Does the result still contain my location?
No. The image is re-encoded, which drops its EXIF data, GPS location and camera details included.
