ByteCutter

Split and merge files easily

Free · In-App Purchases

ByteCutter splits large files into smaller parts you can send anywhere, and puts them back together on any iPhone, iPad or Mac. Email, chat apps and USB drives all have size limits. With ByteCutter you split a video, an archive or a backup into parts of the right size, send them however you like, and the recipient rebuilds the original file with a tap. SPLIT AND MERGE • Split any file by part size or by number of parts, with a simple step-by-step wizard • One-tap destinations: Email, Discord, WhatsApp, FAT32 drives, CD and DVD • Merge the parts back into the original file, verified piece by piece • Received parts open straight in ByteCutter from Files, Mail or Finder, even one at a time • Missing a part? ByteCutter finds it in a folder and adds it for you RELIABLE BY DESIGN • Every part carries a checksum: damaged or tampered parts are detected, never merged into a broken file • Constant memory use, even with files of many gigabytes • Free-space check before every operation BYTECUTTER PRO One-time purchase, no subscription.
