Formo: PDF Compress & Convert

Squeeze a PDF under an e-mail limit, turn a Word file into a PDF, scan a document, or write a note with photos and export it. Everything happens on your iPhone.

Squeeze a 40 MB PDF under an e-mail limit. Turn a Word file into a PDF. Shrink a video small enough to send. Formo does it in seconds, on your iPhone, with nothing uploaded anywhere.

No account. No subscription. No ads. You pay once and every feature is included.

COMPRESS WHAT IS TOO BIG Photos, videos, PDFs, audio and documents. Pick a quality, or tell Formo the size you need — under 25 MB for an e-mail, under 16 MB for a messaging app — and it finds the best quality that fits.

SEE WHERE THE SIZE COMES FROM Before you compress, Formo breaks a file down: how much is pictures, how much is text, how much is the rest. You stop guessing why a PDF is 40 MB.

CONVERT BETWEEN FORMATS Documents: PDF, Word, PowerPoint, Excel, RTF, HTML, TXT, Markdown, CSV. Pictures: JPEG, PNG, HEIC, TIFF, GIF. Video: MP4, MOV, M4V. Audio: M4A, MP3, WAV, AIFF, CAF. Archives: ZIP. Anything that can sensibly become something else, will. Word to PDF keeps the layout. A video can become a GIF, a slideshow of pictures can become a video, a PDF can become a picture of each page.

COMBINE FILES Several files into one PDF, one GIF, one video or one ZIP, in the order you choose.

PDF TOOLS Add page numbers, stamp a watermark, normalize everything to A4, or place two pages side by side for printing.

NOTEBOOK Write a note, drop in photos from your library or scan a page with the camera, then export the whole thing as PDF, Word or HTML — pictures included.

WORKS WHERE YOU DO Share sheet: send a file from any app straight into Formo. Home screen: a widget with what you last worked on, and long-press shortcuts to scan, import or write. Shortcuts: compress and convert inside your own automations.

NOTHING LEAVES YOUR IPHONE Every conversion runs on the device. No upload, no server, no account, no tracking, and nothing that stops working when you are offline.

Buy it once. That is the whole story.
