Compress an image to an exact KB size
Set a target — 20KB, 50KB, 100KB, or your own number — and the tool automatically finds the highest quality that still fits, for exam and job-portal photo uploads with strict size caps.
Files are processed on your device — never uploaded, never stored, never seen by anyone.
How this hits an exact file size
Upload a photo, set your target size (or pick a common preset — 20KB, 50KB, and 100KB cover most exam and job-portal requirements), and click "Compress to target." Instead of you dragging a quality slider and guessing, the tool automatically re-compresses the image at many different quality levels until it finds the highest one that still lands at or under your target — so you get the best possible quality for that exact size limit, not whatever a rough guess produces. If quality reduction alone can't reach a very small target (common with a large original photo and a tiny target like 20KB), it also reduces the image's pixel dimensions and searches again.
This kind of tight size cap shows up constantly on Indian government and exam portals — SSC, UPSC, banking exam applications, and countless state recruitment sites specifically require a passport-style photo between 20KB and 50KB, well below what a modern phone camera produces by default (often several MB). These portals are built for extremely high applicant volumes, which is why the caps are so aggressive compared to a typical file-sharing limit.
