Smaller fileBest quality
Auto-compresses your photo to just under 140KB — useful when a portal allows 150KB.
140KB keeps a photo clearly inside a 150KB cap while holding far more detail than the 20KB–50KB sizes smaller forms demand. It suits document scans and ID photos where the text still has to be readable after compression.
KBPDF finds the quality setting that lands your image just under 140KB, 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 150KB · compress to 100KB · compress to 200KB
Upload your photo and click Convert — the target size is already set to 140KB. The tool finds the best quality that fits under the limit.
Yes for most scans. At 140KB a full-page document keeps its text legible, which is usually the point of the larger limit.
No. Compression happens fully in your browser — important for ID photos and signatures.
