PDF Squeeze: PDF Compressor

PDF Squeeze makes big PDFs small without making them ugly — and it also scans, reads, signs, converts and answers questions about them, without a single byte leaving your iPhone.

SCAN PAPER INTO PDF
Point the camera at a page and PDF Squeeze finds the edges, squares it up and cleans it: shadows lifted, paper turned white, ink made sharp. Choose Auto, Grayscale or Black & White, then save. Every scan is searchable — the words are read on device, so you can find, copy and ask about them.

SEND TO ANY COMPUTER
AirDrop doesn't reach a Windows laptop or a Chromebook. Send to Computer does: type the short address it shows into any browser on the same Wi-Fi and download. No cable, no account, nothing uploaded. Sharing stops when you close the screen.

ASK YOUR PDF ANYTHING
Open a contract, a lease, a manual or a research paper and just ask.

"What's the cancellation policy?"
"When does this renew?"
"What did they agree to pay?"

Answers come with page citations you can tap to jump to the source, so you can check the wording yourself. It all runs on your device: iPhones with Apple Intelligence use the system model, and other iPhones can add an optional on-device model. Scanned and photographed pages are read with on-device OCR in more than twenty languages.

SIGN WITHOUT PRINTING
Sign with your finger, or type your name and pick a handwriting style. Your signature is stored as strokes, never a photo, so it stays crisp at any zoom — and it's baked into the page, so it survives compression and email and nobody can drag it off.

MARK UP LIKE PAPER
Highlight, draw freehand and add text boxes you can stretch to any shape. Undo anything, all the way back.

TEXT STAYS SHARP
Most compressors re-encode every page and hand you a blurry file. PDF Squeeze tries a vector-preserving pass first, keeping text crisp and selectable. Pages are only re-rendered when that actually saves space, and your file never comes out larger than it went in. Filled-in forms keep their answers.

HIT AN EXACT SIZE
Email limit? Upload cap? Pick 1, 2, 5, 10 or 25 MB and PDF Squeeze finds the best quality that fits just under it — or tells you honestly when it can't.

SEE THE DIFFERENCE
Drag the Before & After slider across any page to compare the original with the compressed version.
