How to Compress a PDF on tablet

Updated 2026-09-17 · 2 min read

On tablet, touch controls are sized for fingers rather than a mouse. That is why people end up searching for a way to compress a PDF properly.

Almost all PDF bulk is images. Text weighs nothing, so compression is really a decision about how much image detail you can spare.

PDFfont edits PDF text in the document's own embedded font — no white cover boxes.

Doing it on tablet

Open your browser and choose the file from local storage or cloud sync. Then work through the same steps as anywhere else:

Open the file and check which pages are photographs or scans — those are the heavy ones.

Delete any pages you do not need to send at all.

Export with image downsampling around 150 dpi for screen reading, or 300 dpi if it will be printed.

Check the result opens cleanly and the smallest print is still legible.

When you export, the share or download dialog saves it locally or to the cloud. PDF, PNG and JPG are all available.

Real text is never rasterised, so it stays perfectly sharp no matter how far the images are compressed.

Because it all runs in a browser tab, it also works on managed school and work devices where you cannot add software.

No, only images are affected.

Under 10 MB clears most email limits; under 5 MB is safer.

Yes — any reasonably current browser is enough, regardless of the operating system version.
