How PNG to TIFF under 40KB works
Need to convert PNG files to TIFF? PixelKit does it in one click, right in your browser. It runs a fast binary-search compression loop to land your file under 40KB without visible quality loss — the same technique professional photo tools use, but without asking you to sign up or upload anything. Because nothing is sent to a server, there is no upload wait, no file-size limit from a backend, and no privacy risk. Your photos, ID scans and documents stay on your device the entire time.
The tool works offline after the first page load, on mobile and desktop, and produces standard TIFF files accepted by portals, email clients and design apps. Just set the target to 40KB, drop your PNG file, and download the result. If the first pass lands slightly above 40KB, PixelKit automatically tries again with a tighter quality curve — so you always get the smallest file that still meets the limit.
No account, no watermark, no email gate. Just the file you need, at the size you need it.
