CapsaPDF.

Private PDF toolkit for iPhone and iPad

Every PDF tool.
Nothing uploaded.

Merge, compress, sign, scan and redact, right on your iPhone or iPad. There’s no account to make, and it works without a connection.

Coming soon to the App Store. Free, for iPhone and iPad.

CapsaPDF’s tools: Merge PDFs, Split PDF, Extract pages and Organize pages, then Page numbers and Watermark, under the line: files are processed on this device and never uploaded.

Combine a contract with its appendix, shrink a phone scan small enough to email, sign a form, black out an account number before you send a statement. CapsaPDF does the everyday PDF jobs people usually hand to a website, and does every one of them on your iPhone or iPad. Your files are never uploaded, so there’s nothing to wait for, nothing to sign up for, and nothing left on someone else’s server.

Gone, not hidden.

Black out names and numbers. They’re removed from the file, not covered up.

Find and mark

Nothing marked yet.

Text you can copy from page 1

Before redacting, the name and the account number can still be copied, searched and pasted.

Small enough to send.

Phone scans shrink to a fraction of their size. Text stays sharp.

  • Compress shows the size before and after, so you know it will fit in an email.
  • Make scans searchable: text recognition in your language, on the device.
  • Grayscale for printing.
  • Go from one tool to the next: scan, make searchable, then compress.
Compress PDF in CapsaPDF: compressed from 5.3 MB to 1.4 MB, 73% smaller, with Sign PDF, Add password and Make searchable to continue with.

On iPad, your files sit beside the open document.

  • Run one tool on many files at once; long batches keep going in the background.
  • Share PDFs and photos to CapsaPDF from Mail, Files and Photos.
  • Shortcuts actions: compress, merge, make searchable, images to PDF, get text.
  • Drag and drop and keyboard shortcuts on iPad.

Your files stay yours.

No account, no tracking. Nothing leaves your iPhone.

  • Done on your device. Every tool runs on your iPhone or iPad, text recognition included.
  • Nothing leaves it. CapsaPDF has no network features. Your files are kept in the app, protected by your device’s encryption, until you delete them.
  • No account, no ads, no tracking. CapsaPDF collects no data: its App Store privacy label is “Data Not Collected”.

This page keeps the same promise: no cookies, no analytics and no third-party requests.
