Smaller fileBest quality
Auto-compresses your photo to just under 180KB — the safe margin below a 200KB cap.
200KB is one of the most common upload ceilings, and 180KB is the margin that survives it. You keep almost all the detail a 200KB file would hold, without risking a rejection for landing a few kilobytes over.
KBPDF finds the quality setting that lands your image just under 180KB, so you are not dragging a slider and re-checking the file size. Nothing is uploaded — the compression runs in your own browser.
Also try: compress to 200KB · compress to 150KB · compress to 100KB
Upload your photo and click Convert — the target size is already set to 180KB. The tool finds the best quality that fits under the limit.
Because a file measured at exactly the limit is the one that gets rejected. 180KB clears a 200KB cap with room to spare and looks essentially identical.
No. Compression happens fully in your browser — important for ID photos and signatures.
