Reduce PDF Size in KB (MB to KB)
Free online.

Turn a PDF of several MB into one of a few hundred KB: type the limit (100 KB, 200 KB, 500 KB…) and get a file that fits. Free.

Upload forms often say “PDF under 200 KB” while a phone scan is 2–5 MB. Type the limit into the tool above, or tap one of the sizes, and it makes the PDF small enough with the best quality that fits.

How to do it

  1. Add your PDF to the tool at the top of this page.
  2. The size limit is already filled in. Change it if your form asks for something else.
  3. Press Compress to size. It tries the gentlest settings first and keeps text sharp when it can.
  4. Download the file. The result shows the new size, so you can see it fits before you upload it.

Tips

Questions

Is my PDF stored?

No. The file is compressed in memory and deleted as soon as you get the result. Nothing is kept.

Will the text stay readable?

Yes. It lowers image quality step by step and stops at the best quality that fits. It tells you plainly if a size can't be reached.
