Runs entirely in your browser — your image is never uploaded to any server.
500KB keeps a full photo sharp while making it light enough for websites, blogs, email and messaging apps. Smaller images make web pages load faster, which visitors and search engines both notice.
Tip: For a website, also resize the photo to the largest width it is actually shown at — usually 1200 to 2000 pixels. There is no point sending pixels nobody sees.
How to compress an image to 500KB
- Select the photo or image you want to make smaller — JPG, PNG, WebP or a screenshot.
- Check the target size is 500KB, or change it if your form asks for a different limit.
- Press Compress to 500KB. The tool finds the best quality that fits, and reduces the width and height only if it has to.
- Check the new size and the preview, then download the JPG.
Frequently Asked Questions
How do I compress an image to 500KB?
Select your image, make sure the target is 500KB and press Compress to 500KB. The tool tries the highest quality that fits; if even a low quality is still too big, it reduces the width and height step by step until the file is under 500KB. Then download the JPG.
Will my photo still look good at 500KB?
Yes. At 500KB a photo is visually the same as the original for almost every use.
Will the file be exactly 500KB?
It will be at or just under 500KB — as close to the limit as possible without going over, because that keeps the most quality. Sizes are counted in thousands of bytes, so the file also passes forms that count 1KB as 1,024 bytes.
Can I compress a PNG or a screenshot to 500KB?
Yes. JPG, PNG and WebP images all work, including screenshots. The result is saved as a JPG, which is far smaller for photos; any transparent areas become white.
Is my photo uploaded anywhere?
No. The image is compressed inside your browser on your own phone or computer, and never sent to a server.
