Questions and answers
- Can I compress a photo to an exact size like 50 KB?
- Yes. Set the target in KB and the tool lowers quality and, if needed, size until the picture is under it.
- Which picture formats can I compress?
- JPG, PNG and WebP pictures. iPhone HEIC photos can be turned into JPG first with the HEIC to JPG page.
- Are my files uploaded anywhere?
- No. Your browser opens and processes the files itself, and nothing is sent to our servers. You can check this yourself on the How we do it page.
- Is my original photo changed?
- No. You get a new file to download and the original stays where it is. Check the result before you replace anything.
- Is Compress image really free?
- Yes. There is no sign-up, no watermark and no limit on how many files you use it for.
- Does it work on a phone?
- Yes. It works in the browser on phones, tablets and computers. A very large file can be slow on an older phone because everything runs on the device.
