Frequently asked questions
- How do I compress a photo to under 50 KB?
- Add the photo, choose 50 KB and press Compress. The tool keeps the highest quality that fits under the limit.
- Will the result be exactly the target size?
- It will be at or just under the target, which is what upload forms check. Quality is lowered first and the image is only made smaller if that is not enough.
- Are my photos uploaded anywhere?
- No. Compression happens on your device and the files never leave your browser.
- What do mm, inch and DPI mean here?
- Some forms give the photo size in millimetres or inches. Enter that size and the DPI the form mentions, usually 200 or 300, and the tool converts it to pixels.
