Why compress an image to an exact size?
Plenty of official websites reject a photo unless it falls under a strict byte limit — and 20 KB is one of the tightest. Government identity portals, exam-registration sites, scholarship applications and some banking forms specify limits like 'photo must be 10–20 KB, JPG'. A normal phone photo is two to five megabytes, a hundred times too big, so the upload fails with an unhelpful error.
A plain compressor or converter won't reliably hit 20 KB, because you can't predict the final size from a quality slider. This tool works the other way around: you give it the target, and it searches for the right settings to land at or just under it.
How the tool reaches the target size
When you drop an image in, the tool repeatedly re-encodes it as JPG, lowering the quality step by step and, if needed, shrinking the dimensions, until the file fits inside your target. All of this happens on a canvas inside your browser — the image is never uploaded, which is important when the photo is an ID document or passport picture.
Because 20 KB is so small, the result is a low-resolution image suited to a thumbnail-sized photo box on a form. That is exactly what those forms expect; they only need a recognisable face, not a print-quality portrait. If your form allows a larger limit such as 50 KB or 100 KB, use that target instead for a sharper photo.
Getting an acceptable photo at 20 KB
Start from a tightly cropped photo. The fewer pixels the tool has to keep, the more quality survives at 20 KB — crop to just the head and shoulders before compressing, the way passport photos are framed.
A plain, light background compresses far better than a busy one, because JPG spends fewer bytes on flat areas. If your form lets you choose, a photo against a white wall will look noticeably cleaner at 20 KB than the same shot against a cluttered room.
Always download and open the result before uploading it to the form, so you can confirm the face is still clear at the reduced size.
Questions fréquentes
- How do I compress an image to 20KB?
- Drop your image above and Pixaru automatically lowers the quality (and, if needed, the dimensions) until the file is 20KB or smaller, then you download it. It all happens in your browser — nothing is uploaded.
- Why would I need an image under 20KB?
- Many government, exam, visa and job-application portals reject photos above a strict size limit such as 20KB. This tool guarantees your image meets that limit so your upload isn't rejected.
- Is my photo uploaded anywhere?
- No. Compression runs entirely on your device, so your photo or ID image never leaves your browser — safe for passport, visa and official documents.
