FAQ

Will my photos lose quality?

The balanced preset keeps photos looking the same at normal viewing size. Choose High quality to keep fine detail, or Smallest for the lowest file size.

Why is my PNG not smaller?

PNG is lossless, so re-saving it rarely helps. Convert it to WebP or JPG for a much smaller file.

Are my photos uploaded?

No. Everything runs in your browser, so your photos stay on your device.

Does it work on my phone without an app?

Yes. Open this page in your phone's browser, pick photos from the gallery, compress and download. Nothing to install.

How many photos at once?

Up to 50, each up to 50 MB. Download them one by one or as a single ZIP.
