Compress an image to 500 KB
To compress an image to 500 KB, drop it in: the tool is already set to 500 KB. It lowers the quality and, if it has to, the pixel size until the file fits, then shows the result. Nothing is uploaded.

How it works
- Drop your picture into the box above.
- The size is set to 500 KB. Change it if your limit is different.
- Check the result and download it.
When do you need 500 KB?
A 500 KB limit is common for larger document scans and product pictures.
What 500 KB means for a photo
A 12-megapixel phone photo is 3 to 6 MB, so 500 KB is a big reduction. At this size a picture about 1830 pixels wide keeps good quality; much larger than that and the tool has to compress harder, which shows as blur and blocks.
Tips
- Crop to what you need first: fewer pixels mean a smaller file at the same quality.
- Start from the original photo, not a copy sent over a chat app.
- For photos, JPG or WebP reach the target far better than PNG.
Questions people ask
How do I compress an image to 500 KB?
Drop it in the tool above, which is set to 500 KB, and download the result.
Will the picture look worse at 500 KB?
A little: 500 KB is much smaller than a camera photo. Cropping and shrinking the pixels first keeps it looking clean.
Why do some sites count 500 KB differently?
Some systems count 1 KB as 1000 bytes and others as 1024. To be safe, aim a little under the limit. The exam and size pages land inside an exact window.
Is it free?
Yes. No signup, no watermark, and no limit on how many pictures you compress.
Is my picture uploaded?
No. Compression happens in your browser, so the picture never leaves your device.
