Passing a 20KB document-photo cap
An exam or visa portal caps the photo at 20KB and rejects yours. Bring the JPG under the cap here and re-upload it - no account, and your document photo is never sent to us.

Twenty kilobytes is the territory of the strictest upload caps - government examination portals, older job boards, and identity-document forms that reject anything larger. Reaching it takes real compression, and this tool is candid that a photograph squeezed this hard will show the strain around fine detail and text. The aim is simple and narrow: clear the twenty-kilobyte gate while keeping the picture as readable as that ceiling physically allows, rather than pretending a full-quality photo can survive at a size this small. Twenty kilobytes from a JPG is the hardest squeeze in the JPG family, the figure demanded by the most unforgiving exam and government portals, and the one where starting from a clean original matters most. It takes a JPG and hands back a JPG, re-encoding it at the quality - and, only where unavoidable, the dimensions - that bring it under the target while leaving the format unchanged. It all happens in this browser tab: your JPG is decoded, re-encoded and returned without a single byte reaching a server, which for a personal photo or an identity document is exactly how it should be. The tool looks for the highest quality that still fits 20KB, so you receive the best-looking result that satisfies the limit rather than a picture crushed harder than it needed to be.
Shape and export choices
- Select your JPG. Its dimensions are read in the browser first, so the compressor knows exactly what it is working with.
- The JPEG quality setting is tuned by a binary search toward 20KB, since a JPG's file size is governed chiefly by that quality dial.
- Should the quality floor still leave the file above 20KB, the picture is scaled down and re-tested, so the target is met one way or another.
- Check the reported size against 20KB and save the result, which never left this browser tab.
Good fits for Compress JPG to 20KB
The last resort before it fits
When a system simply will not accept anything larger, 20KB is often the only figure that works. This gets your JPG there while keeping it as legible as the limit permits.
Check the image before download
- The target is a ceiling, not an exact figure: the result lands at or under 20KB, and usually close to it, because forcing an exact byte count would mean padding the file with meaningless data.
- JPG is lossy: every save discards a little more detail. Compressing an already-compressed JPG hard can raise blocky artefacts around edges and lettering, so begin from the highest-quality original you have rather than a file that has been saved repeatedly.
- A very large or detailed source may need its dimensions reduced to reach 20KB. The tool reports the final pixel size, so the trade-off is never hidden from you.
Questions about Compress JPG to 20KB
Why does my JPG look rough at 20KB?
Twenty kilobytes is extremely small for a photo, so visible compression is unavoidable. The tool keeps it as clear as 20KB allows, but a larger limit will always look better if the form accepts one.
Will the file be exactly 20KB?
It lands at or just under 20KB. An exact byte count would require padding the file, so the tool instead keeps the largest quality that stays within the limit.
What if it cannot reach 20KB?
If even the smallest usable dimensions leave the file above 20KB, the tool tells you plainly rather than returning an unusable, over-compressed image.
