To compress a PDF to 100 KB, SafeResize turns the pages into lighter pictures until the file is 100,000 bytes or less, which is under 100 KB whether a website counts 1 KB as 1,000 or 1,024 bytes.
| 100 KB in bytes | 100,000 bytes, or 102,400 bytes when 1 KB is counted as 1,024 bytes, as Windows does |
|---|---|
| 100 KB in MB | 0.1 MB, or 0.0977 MB as Windows counts |
| The PDF you download | 100,000 bytes or less, so both counts accept it. Windows shows it as 97.7 KB or less. |
| Each page gets, shared evenly | About 50 KB with 2 pages, or 20 KB with 5 |
| Sharpness of each page | 150 DPI first, then 120, 96, 72, 56 and 45 DPI, stopping at the first that fits |
Need 75 KB? Type 75 in the size box below, in place of 100.
Many application portals accept documents of up to 100 KB each. A phone scan of one page is often 1 to 3 MB, so it has to shrink by 90% or more to fit.
This page opens the PDF tool with 100 KB already filled in. Add your PDF, check the preview, and press "Make it this size". The file you download is just under 100 KB, counted either way (100,000 or 102,400 bytes).
A limit is shared by every page of the PDF, so the number of pages matters more than anything else. Shared evenly, 100 KB gives each page about:
For one to three pages, usually yes. SafeResize turns each page into a picture and lowers the sharpness only as far as it has to. You see the result before you download it.
No. Each page becomes a picture, which is what makes such a small file possible. Text can no longer be selected, and form fields, links, bookmarks and digital signatures are not kept. Keep your original PDF for everything else.
No. The PDF is processed inside your browser and never leaves your phone or computer.
