Questions and answers
How much smaller will my images get? +
It depends on the image. Photos straight from a phone or camera often shrink a lot at 60–80% quality, especially if you also set a max width. Images that were already compressed may only shrink a little.
Why did my PNG not get smaller? +
PNG is lossless, so re-saving it at the same size rarely helps. Convert it to WebP or JPG, or reduce its width. If a result would be bigger than the original, the tool keeps the original file.
Are my photos uploaded anywhere? +
No. Compression runs in your browser with the Canvas API. The files never leave your device.
Does compression remove EXIF data? +
Yes. Re-encoding through the canvas drops metadata such as camera model and GPS location, which is useful for privacy before sharing photos. The only exception is a file the tool keeps unchanged because compressing it would not make it smaller.
Can I compress many images at once? +
Yes. Add as many images as you like, compress them in one go and download them together as a ZIP file.
