How it works

  1. 01

    Add your PDF

    Drop in a .pdf, or click to browse. It is uploaded privately over TLS and deleted after 1 hour.

  2. 02

    We find the sharpest images that fit

    Ghostscript rewrites the PDF with its images at 220 dpi, then 180, 150 and lower, and keeps the first version at or under 2 MB. Text and vector drawings are not downsampled.

  3. 03

    Download it

    Grab the compressed PDF, ready for any form, portal or email with a 2 MB limit.

What a 2 MB target does to real PDFs

We ran three kinds of PDF through the same engine this page uses, with a 2 MB target.

  • A 6 page scan with photo pages at 300 dpi, 3.48 MB: 1,039 KB, with the images at 180 dpi. The 220 dpi version was over 2 MB, so the engine took the next step down.
  • A 6 page report with text and photos, 4.12 MB: 360 KB, photos kept at 220 dpi, the highest step, because the target was easy to meet.
  • A 20 page vector drawing with no photos, 4.42 MB: 3.56 MB, target missed, because there were no images to shrink.

That is the point of the larger target: the same scan at the 1 MB target drops to 150 dpi. For big scans, 5 MB keeps even more.

What 2 MB holds in a PDF

2 MB is 2,097,152 bytes. Page images are re-encoded from 220 dpi down to 32 dpi until one fits.

Common questions

Why 2 MB?+

2 MB is a common attachment and upload limit, and it leaves more room than 1 MB, so photos and scans keep more of their detail.

How exact is 2 MB?+

The target is 2,097,152 bytes, which is 2 MB as Windows counts it. Some upload forms count 2 MB as 2,000,000 bytes instead. If a portal still says the file is too big, use the 1 MB target, which leaves room under either count.

Will my text stay readable?+

Yes. Only images are downsampled. In our tests the text stayed real, selectable text with every character intact, and links and bookmarks were kept.

What happens to form fields?+

A filled form field is flattened: its value stays visible on the page as text but can no longer be edited. Compress the PDF before you fill in or sign it.

What if it can't reach 2 MB?+

Then the PDF has little image data to shrink. A 20 page vector drawing of 4.42 MB came down only to 3.56 MB. You get the smallest version we made, never a broken file, and the page tells you the target was missed.

Is my PDF private, and is there a watermark?+

It is uploaded over an encrypted connection, compressed on our server, and both the upload and the result are deleted after 1 hour. No account and no watermark.
