Compress a PDF Online
Make a PDF file smaller while keeping it readable, free, in your browser or the JUST NODU app.
How to compress a PDF
- Tap Compress a PDF above.
- Choose your PDF.
- Pick a level: Less compression (best quality), Recommended (good quality, much smaller) or Extreme (smallest file, lower picture quality).
- Download the smaller PDF. If it is still too big for an upload form, try the next level.
Compress a PDF to an exact size (200 KB, 100 KB, 1 MB)
Many forms (exams, jobs, government portals) accept only files under a size such as 100 KB, 200 KB or 500 KB.
- Open the PDF on justnodu.com.
- Tap Save and choose PDF.
- Under File size, turn on Make the file smaller, I choose the size and type the size, for example 200 KB.
- Download. The pictures inside are compressed (and made smaller if needed) so the file fits.
The same works for JPG and PNG pictures, and when you merge pictures into one PDF. A very small size makes pictures softer, so use the biggest size the form allows.
What makes a PDF smaller
Most of a PDF's size is usually its pictures. Compression stores them at a sensible resolution and quality for screens and printing; text stays sharp at every level.
Privacy
Your file is sent over an encrypted (HTTPS) connection to our server only to make the preview or the export you ask for, and it is deleted automatically when that is done. See the privacy policy.
Questions
Is it free?
Yes.
Will the text get blurry?
No. Text stays sharp; only pictures are made lighter, most of all on Extreme.
Can I choose an exact file size?
Not exactly: choose a level, check the new size, and use a stronger level if you need it smaller.
