Drop a photo and get it back under 20KB, automatically. Free and private.
A 20KB limit is one of the tightest you will meet, and it usually comes from older government portals and exam registration forms that were built when connections were slow. Signature uploads in particular are often capped around this size.
Forms almost never explain how to meet their limit. They reject the upload, show a red message and leave you to work it out. This page exists so you can drop the file in and get one that fits.
20KB is double the 10KB limit and is common for signatures and small photographs on application forms. It is enough for a clear signature or a recognisable face, but not for fine texture or small print.
A photo at this size is typically a few hundred pixels across. The tool picks the largest dimensions and the highest quality that still fit under 20KB, so you do not have to guess at either.
Plain, evenly lit backgrounds compress far better than cluttered ones, so a photo taken against a light wall will look noticeably cleaner than the same face in front of a bookshelf.
Avoid photographing a screen or a printout if you can. Re-photographed images carry glare and moiré patterns that take up space without adding anything you want to keep.
Drop your image above. It is automatically compressed until it fits under 20KB, then you download it. No settings to work out.
For most photos, yes. The tool reduces quality and dimensions gradually until the target is met, so it takes the least damaging route available. Very small targets on a very detailed photo will visibly soften it — that is unavoidable at any tool.
JPG, PNG and WebP all work. The result is always a JPG, since that is what form uploads expect and what compresses best for photographs.
20KB is extremely small for a photograph. The tool gets you under the limit, but a detailed colour photo cannot retain much at that size. Cropping tightly first helps a great deal.
Drop your image above. The tool shrinks it to under 20KB automatically, keeping the best quality that fits. If the picture is very large, it is also scaled down, which is what makes 20KB reachable. Free, private, nothing uploaded.
Because 20KB leaves little room for detail, the dimensions are reduced along with the quality. Start from a tightly cropped original on a plain background and the result will be noticeably sharper.
No. The work happens in your own browser, so the file never leaves your device.
