Compress one image or a whole batch to 15 KB each. Handy for signatures and very small form images. The tool sets the JPEG quality automatically to hit the size you need, then lets you save each file or all of them as a ZIP. Nothing leaves your device.

This free tool reduces your pictures to 15 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 15 KB at the best quality that still fits.
A 15 KB limit sits between a signature size and a small photo size. Some forms set it for signatures, and a few ask for a small passport style photo at this size. It suits simple images more than detailed ones.
15 KB is a very small budget for an image, so the tool lowers the resolution as well as the JPEG quality to reach it. That works nicely for signatures and small thumbnails. For a full face photo you will get a cleaner result with a larger target such as 50 KB or 100 KB. For an even smaller file, try compress to 10 KB. For higher quality with more room, use compress to 20 KB.
Add a single picture or a whole batch and each one is compressed to 15 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.
What is a 15 KB limit usually for? Most often a signature, sometimes a small ID photo on a strict form. It is a middle ground between 10 KB and 20 KB.
Can I fit a face photo in 15 KB? A small, simple head shot can fit, though detail will be limited. For a sharper result use 20 KB to 50 KB.
Need a different limit? You can also 5 KB, 10 KB, 20 KB, 20 to 50 KB, 25 KB, 30 KB, 40 KB, 50 KB, 100 KB, 150 KB, 200 KB, 300 KB, 500 KB, 1 MB and 2 MB. For any custom size, use the image size reducer.
Everything happens in your browser using your own device. Your images are never uploaded to a server, there is no account or sign up, and no watermark is added. Close the tab and nothing is left behind, which makes this a safe way to prepare photos, signatures and documents for upload.
