How to make a PDF under 100 KB

  1. Choose your PDF

    Pick a PDF from your phone or computer. Up to 25 pages are opened.

  2. Check the limit

    The limit is already set to under 100 KB. You can pick another one, or type your own.

  3. Take out pages (if you like)

    Remove the pages you do not need, turn a page that is on its side, or move a page up or down. Fewer pages make a smaller file.

  4. Make it smaller and save

    Tap Make my PDF smaller. You see the new size, and the old one, before you tap Save file.

Why use this tool

Under 100 KB

The file is made to fit under 100 KB. If that is not possible, you are told, and shown the smallest it can be.

Scans stay readable

Pages are made lighter step by step, and only as much as needed. The Document look turns paper white and writing dark, so a small file is still easy to read.

Text stays text when it can

A PDF that is already under 100 KB is kept as it is. If the pages you keep fit as they are, they are copied without change.

Take pages out, turn them

Remove pages, turn them or change their order before you make the file.

Private

The PDF is read and made in your browser, on your device. It is not sent to a server.

No watermark, no account

Your PDF is clean, and you do not need to sign in.

Tips for a PDF under 100 KB

Questions

How do I compress a PDF to 100 KB?
Open the tool, choose your PDF, and tap Under 100 KB (or type the number). Then tap Make my PDF smaller and Save file.
Will my PDF look blurry?
A scan of paper is made into lighter pictures, step by step and only as much as needed. Small limits on many pages can look soft. The Document look makes writing darker and paper whiter, which helps.
Can I still select the text afterwards?
If your PDF is already small enough, or the pages you keep fit as they are, the text stays text. If the pages have to be made into pictures to fit, the text is part of the picture and cannot be selected.
What if it does not fit under the limit?
You are told, and shown the smallest file it can make. Take out some pages, try the Document look, or choose a bigger limit.
Can I take out pages?
Yes. Remove any page before you make the file. The pages you keep make the new PDF.
My PDF has a password. What do I do?
Open it, take the password off with the program that made it, save it, and try again. Nova Forms cannot read a locked PDF.
Is my PDF uploaded?
No. The PDF is read and made in your browser, on your own device. Nothing is sent to a server.
Does it work on a phone?
Yes. It is made for phones, with big buttons. Chrome, Edge and Safari all work.
