Compress PDF to 10 MB

How to compress a PDF below 10 MB

1. 1

   Choose a PDF

   Click Choose PDF or drag the file onto the page. The file stays on your device.

2. 2

   Click Compress PDF

   The 10 MB limit is already set, so there is nothing to type. If the PDF is already under 10 MB, you get it back unchanged.

3. 3

   Check the result

   You will see the size before and after. If the file cannot get down to 10 MB, the page tells you how much too big it is and shows the Try a lower resolution button.

4. 4

   Download the file

   Before the download we check that the smaller PDF opens, has the same number of pages and has not lost any text.

What fits in 10 MB

10 MB is a lot for a text document, so this limit is mostly exceeded by long papers with photos, reports full of charts and multi-page scans. Making the photos smaller is usually enough, and the text and page layout stay the same. If you are emailing the file to a mailbox with a 10 MB limit, set a custom limit of 7168 KB in Compress PDF, because an attachment grows by about a third when it is sent.

Where you will see a 10 MB limit

A 10 MB limit helps with larger documents such as theses, reports and paperwork sent through a portal. The limit is a ceiling, so the finished file usually comes out a little smaller than 10 MB. The tool counts 1 KB as 1,024 bytes and 1 MB as 1,024 KB. If the form counts differently, or you are not sure how it counts, set a custom limit with a small margin on the main Compress PDF page.

In a thesis or an annual report, high-resolution photos and screenshots usually take up the most space. The size of a PDF depends more on photos, scans and fonts than on the number of pages. A text-only document often fits with no visible change, while a scan may need its pages saved at lower quality. After downloading, compare important details, signatures, stamps and thin lines with the original.

What to do if the PDF will not fit in 10 MB

If the file cannot get below 10 MB, you can download the smallest version the tool managed to make and see how far over the limit it is. Then click Try a lower resolution. The file may get smaller still and the text stays selectable, but photos, stamps and thin lines will be less sharp, so look at the result before you send it.

If that is still not enough, cut down the document, not its readability. Use Delete PDF pages to drop pages the recipient does not need, keep only the required ones with Extract PDF pages, or Split PDF into several smaller files. If the recipient accepts bigger files, choose a higher limit in Compress PDF.
