Questions
›Why 300 KB?
It's a common cap for supporting documents in online applications where 100 KB is too tight for a multi-page scan. At 300 KB, two or three scanned pages can usually keep a higher resolution than 100 KB allows, so they read well on screen and print legibly.
›What if my PDF is already under 300 KB?
You get it back after a lossless repack, which sometimes trims a little more, and the photos are left untouched. Nothing is made worse just to hit a number.
›Does "100 KB" mean 100,000 or 102,400 bytes?
We aim under 1 KB = 1,000 bytes, the stricter of the two. A file that fits here also passes an upload form that counts 1 KB as 1,024 bytes, so you never have to guess which one a site uses.
›Are my files uploaded anywhere?
No. Your files are processed on your own device by your browser. They never touch our servers, so there are no upload waits, no size caps from us, and nothing to delete afterwards.
