SlimScan: Scan or Shrink PDF

Attachment too large? Type the limit, like 500 KB, and SlimScan makes one small PDF that fits. Scan paper or shrink the PDFs you have. Works offline, on your iPhone.

Tired of "Attachment too large"?

SlimScan scans paper and shrinks the PDFs you already have: 20 pages in under 1.5 MB. Everything happens on your iPhone.

SHRINK THE PDFs YOU ALREADY HAVE • Share any PDF to SlimScan from Mail, Files, WhatsApp or Safari, or tap Shrink a big PDF. • SlimScan rebuilds it as a small, sharp PDF and shows what you saved (was 14 MB, now 1.3 MB). • Works with any PDF: reports, slides, web pages, not just scans.

SMALL. REALLY SMALL. • About 75 KB a page, often a tenth of a normal phone scan. • Choose Small, Email or Sharp, or set your own limit with Custom. You see the exact size and a tick before you send. • Text pages turn crisp black and white; colour pages stay in colour. • Paper size (A4 or Letter) follows your region.

UPLOAD LIMITS • Online form with a 500 KB limit? Choose Custom, type 500 KB, and see the exact size and a tick before you upload. • Job applications, insurance claims, visa portals, school forms: every page in one small PDF. Scan them, or add photos and PDFs. Works offline.

SCAN AND FIX • Scan document uses Apple's document camera: edge detection, perspective correction, several pages in a row. • Photos to PDF turns your photos into one small PDF. • Tap a page to leave it out. Crop, rotate or reorder; Remove glare combines two photos of glossy paper.

MORE TOOLS • Remove hidden data: see and remove location, camera, dates and names in photos and PDFs. • Copy text from any page. • ID & visa photo: pick the document and SlimScan frames your photo to its size, with a plain background and a quality check. Saved as a photo file for online forms, or as a print sheet for offices that accept printed photos. A guide, not a guarantee: confirm the rules with the issuing office. Not affiliated with any government. • Share as pictures (JPG), email, print with AirPrint, or keep it in Saved (also in the Files app).

PRIVATE BY DESIGN • Processed on the device. No account, no tracking, no ads. • Nothing leaves your iPhone unless you send it. Works in flight mode. • SlimScan never asks for access to your photo library: you pick each photo yourself. • Made in Switzerland, where privacy is the standard, not an extra.
