Frequently asked questions
How do I compress an image to exactly 500 KB?
Drop it in β the 500 KB target is already set β and the tool binary-searches the highest quality that still fits, then hands you the file. No slider guesswork.
Is my image uploaded to a server?
No. Compression runs entirely in your browser; the image never leaves your device.
Which formats can I use?
JPG, PNG and WebP input. Output is JPG (works everywhere) or WebP (smaller).
Where the 500 KB limit shows up
The 500 KB target usually comes from high-quality web images, portfolio shots and any upload capped at half a megabyte. Set it above and download a file that lands just under the cap.
What to expect at 500 KB
At 500 KB compression is effectively invisible for a single photo. Use it when quality matters more than tiny size.
A quick tip
For a website you control, exporting to WebP fits even more quality into 500 KB β convert after compressing. For other targets, use the image compressor hub.
