To compress a PDF to 300 KB, SafeResize turns the pages into lighter pictures until the file is 300,000 bytes or less, which is under 300 KB whether a website counts 1 KB as 1,000 or 1,024 bytes.

300 KB sits between the tight 200 KB limit and the roomier 500 KB one, and some upload forms cap each document at exactly that. Split evenly, a 5-page PDF gets about 60 KB a page, so how many pages you send matters as much as how you scan them.
The PDF tool below opens with 300 KB filled in. Add your PDF, look at the preview, and press "Make it this size". If your PDF is already under 300 KB, the tool tells you and you keep the original.
About, yes. Websites count a kilobyte as 1,000 or 1,024 bytes, so 300 KB is 300,000 or 307,200 bytes. SafeResize keeps the file under 300,000 bytes, so it passes both ways.
For a long PDF, tick "Black & white", or send only the pages the form needs (take the others out in your PDF program). When a size cannot be reached, the tool tells you the smallest it could make, so you know how far off you are.
No. The work happens inside your browser, so the PDF never leaves your phone or computer.
