## What is PDF Diet?

Shrink a PDF before you email it or upload it from your iPhone or iPad. Open a scanned form, a report with photos, or another large PDF from Files. PDF Diet compresses it right on your device, so you can work offline.

Find the right file size
Choose Light, Medium, High, or Strong. Check the file size for each preset and compare the original and compressed pages in a synchronized preview. See what changed before you share.

Keep documents readable
PDF Diet checks what’s inside the document. On supported PDFs, it can recompress embedded images while keeping text and vector graphics sharp. Results depend on what’s in the file.

Clean up a copy
Delete unwanted pages or choose which details to remove, including author metadata, comments, bookmarks, attachments, and links.

Save to Files or share
Export a separate copy and keep your original intact. Save the result to Files or send it through the share sheet with Mail, Messages, or AirDrop.
