Merge without limits
Stack as many files as you want into a single document. Drag them into the order you want, not the order they were scanned.
Tornado PDF turns your iPhone and iPad into a real PDF workbench. Merge a stack of receipts on the bus, crop a scan at the cafe, sign a contract in the back of a cab. It all happens on the device you already have.
We focused on the tools people open every week, then made them feel calm instead of cluttered. Nothing gets sent somewhere you did not ask for.
Stack as many files as you want into a single document. Drag them into the order you want, not the order they were scanned.
Pull out the two pages that actually matter. Leave everything else where it belongs.
See the real page, not a placeholder. Straighten sideways scans in seconds. Tighten margins before you print.
Shrink a chunky file to something you can actually email, while keeping the text crisp.
Draw a signature, drop it on the line, you are done. Or bring a digital certificate if that is what the office wants.
Turn a PDF back into something editable when you need it, including images and HTML input.
Make old photocopies searchable. The text you scanned becomes text you can copy.
Lock a document before you send it. Cover the sensitive parts so they never come back to haunt you.
Run the same operation on a folder full of files. Save the output, move on with your evening.
Every plan removes ads, unlocks every Premium tool, and renews automatically through your Apple ID. You can cancel any time from the App Store.
Great for a one off busy week when you suddenly need every tool at once.
The sweet spot for people who work with PDFs a few times a week.
Our best value. Roughly the price of one paperback for a whole year of tools.
