Shrink a scanned or exported PDF below an attachment limit without touching a desktop app.
A scanned contract or a multi-page report exported from another app routinely lands well past the size limit most email providers and upload portals allow, and there is rarely a clean way to shrink a PDF from the Mail app itself. This shortcut fixes that with one action: pick the file and run it through Filemorph's Compress PDF action, which tries two different compression strategies on the phone's own graphics stack — re-encoding the embedded images, and re-serializing the document to drop redundant PDF objects — then keeps whichever result comes out smaller. A bank statement or signed contract never has to be handed to a website just to get small enough to attach. Share the result straight from the same shortcut.
There's no one-tap install for this one yet — add each action below in the Shortcuts app and you'll have it running in about two minutes.
No. Compress PDF runs locally; the shortcut works in Airplane Mode, which matters for anything you would not want to hand to an unknown web compressor.
No, Compress PDF is a Filemorph Pro feature ($29.99/year, 7-day trial). Filemorph's free tier covers image conversions and PDF text extraction, not PDF compression.
Every action in this recipe runs entirely on-device — no upload, no account.
