Compress Image to 300 KB

This free tool reduces your pictures to 300 KB each, right inside the browser. Plenty of websites, government portals and application forms cap uploads at a fixed size, and a file that is even a little too large gets rejected. Instead of guessing with a quality slider, you add your photos and every one is brought to 300 KB at the best quality that still fits.

Why compress to 300 KB

300 KB is handy for detailed scans and higher quality images on sites that allow a larger file. It is common for document uploads and for photos where clarity matters more than a tiny file size.

Quality and size at 300 KB

300 KB is generous, so most web sized photos stay close to their original quality. The tool only trims the file enough to fit, which means very little visible change. For an even smaller file, try compress to 200 KB. For higher quality with more room, use compress to 500 KB.

Compress many images at once

Add a single picture or a whole batch and each one is compressed to 300 KB on its own. Every file keeps its name with the size added, so they stay easy to tell apart. Download any image with its own button, or use the download button to save them all together in a ZIP when you have more than one. It works the same on a phone and a computer.

Common questions about 300 KB

What needs a 300 KB limit? Detailed document scans, certificates with fine print, or photos that should stay sharp. 300 KB keeps them clear.

Will 300 KB keep my image looking original? For most web sized images, yes. Compression at 300 KB is light, so the result looks almost identical.

Other target sizes

Need a different limit? You can also 5 KB, 10 KB, 15 KB, 20 KB, 20 to 50 KB, 25 KB, 30 KB, 40 KB, 50 KB, 100 KB, 150 KB, 200 KB, 500 KB, 1 MB and 2 MB. For any custom size, use the image size reducer.
