Compress an image to 50 KB

Portals enforce small image sizes to keep uploads fast and storage predictable — job portals, visa applications and signature/photo fields with a 50 KB cap are the classic cases. The check is automatic: even slightly over and the form rejects it, so compressing to just under 50 KB is the reliable fix.

For the intended use (an ID-style photo or signature displayed small), yes. The tool lowers quality first and touches dimensions only if needed, so you always get the sharpest image that fits under 50 KB.

No. Compression runs entirely in your browser on your device. These uploads are usually ID photos and signatures — exactly what you don’t want on a stranger’s server, which is why PDFAgent never receives them.

Yes — and verifiably so. PDFAgent has no upload step: your file is processed by JavaScript running in your own browser and never leaves your device. You can open your browser’s network panel (or even go offline after loading the page) and confirm that no document data is transmitted.
