How many images can I compress at once?

Up to 200 images per batch, up to 50 MB each. They are processed one after another to avoid running out of memory: a batch of 100 phone photos takes about a minute on a normal computer.

Which quality and maximum width should I choose?

For the web and social media, 70–80% quality with a 1920 px maximum width cuts a phone photo by 70–90% with no visible difference. For email, 1280 px and 70%. To keep print quality, keep the size and use 85–90%.

Can an image get bigger after compressing?

No. If compressing an image would produce a larger file (it happens with already optimized images), the original file is kept.

Does it support iPhone HEIC photos?

Yes. HEIC photos are decoded and compressed automatically, and saved as JPG so they open anywhere.

Are my files uploaded to a server?

No. Everything is processed inside your browser and your files never leave your device. There is no upload, no queue and no temporary storage, so the tool keeps working even if you go offline after the page has loaded.

Yes. There is no sign-up, no watermark and no daily limit. The site is funded by a few unobtrusive ads around the tools, never inside your files.
