Compress a PDF

Scanned PDFs and documents full of photos get huge. Morph re-saves the images inside at screen resolution, so the file shrinks a lot while text stays sharp and selectable.

How to do it

Open the PDF in Morph
Drag it and tap ⌘ (Ctrl on Windows) for the Tools wheel, or share it to Morph on iPhone and Android.
Choose Compress
Morph shows the new size, like 8.4 MB → 1.2 MB.
Send it
The smaller PDF is saved next to the original, which stays untouched.

Where it works

Mac Yes.
Windows Yes.
iPhone and iPad Yes, and in Shortcuts with Compress Files.
Android Yes, along with photos and videos.

Free and open source. Everything runs on your device: no uploads, no account, no ads, and your originals are never changed.

Questions

Will the text still be selectable?

Yes. Morph only re-encodes the images inside the PDF; text and vector drawings are kept as they are.

Why didn't my PDF get smaller?

PDFs that are mostly text are already small. Morph says so instead of making a bigger file.

Is it safe for confidential documents?

Yes. Nothing is uploaded; the PDF is processed on your device.
