About the Compress Image to 500 KB
500 KB limits are common for document uploads, website and blog images, email attachments that need to stay small, and listings on shopping and classified sites.
Upload forms check the file size, not how the picture looks, so a photo that is 2 MB from your phone is rejected even if it looks fine. This tool measures the real file as it compresses: it tries the highest JPEG quality first, lowers it step by step until the file is under 500 KB, and makes the image smaller only if quality alone is not enough. At 500 KB, photos usually keep their full dimensions. Choose WebP for websites if the site accepts it, since it looks better at the same size.

- PNG files are saved as JPG in target mode, since PNG has no quality setting to lower. Transparent areas become white.
- If an image cannot reach 500 KB even at a very small size, the smallest version is offered and clearly marked as still too big.
- Some forms also need exact pixel dimensions. Use Resize Image or Passport Photo Maker first, then compress.
Frequently asked questions
Can I compress several photos to 500 KB at once?
Yes. Add up to 30 images; each one is fitted under 500 KB on its own, and you can download them together as a ZIP file.
How do I get exactly 500 KB?
Forms ask for a maximum, so the tool keeps the file at or just under 500 KB at the highest quality that fits. It never goes over the limit.
Does it work on my phone?
Yes. Choose a photo from your gallery or take one with the camera. Everything runs in the phone's browser, so it also works on a slow connection once the page has loaded.
Are my files uploaded?
No. Files are opened and processed in your browser, in a background thread. Nothing is uploaded, so the tool also works for confidential documents.
