## What is Blot PDF?

Need to share a contract, form, invoice, or report without exposing private details? Blot PDF helps you find sensitive information, choose exactly what to hide, and make a new PDF with those areas permanently covered.

FIND WHAT MATTERS
Search for names, addresses, account numbers, company names, or any words across every page. Blot PDF can also suggest email addresses, US phone numbers, Social Security numbers, and valid payment card numbers. Scanned pages can be read with on-device OCR.

YOU CONTROL EVERY HIDDEN AREA
Review suggestions before applying them. Select text or draw over signatures, photos, QR codes, and other content. Move or resize an area, undo mistakes, and hide just the first five digits of an SSN when precise text positions are available.

SHARE A SECURE COPY
Blot PDF creates a new flattened PDF and checks the export before sharing. Your original stays untouched. Document processing happens on your iPhone or iPad, with no account or document upload.

TRY IT FREE
Your first three successful secure exports are free. Corrections to the same open PDF do not use another free export. Blot PDF Pro unlocks unlimited exports with one lifetime purchase. No subscription.

Always review every page. Automatic suggestions may miss information you want to hide.
