About

Arthize is a private, hosted PDF workspace that puts 50+ tools in one place — merge, split, convert (to/from Word, Excel, images), sign, OCR, redact, compress, watermark, protect and more. Instead of scattering documents across a dozen free-but-ad-heavy sites, you work in one clean workspace where files are processed privately and auto-deleted after each job — never used to train models, sold, or mined. There’s a free-forever tier (no card), Pro from $6/month or $48/year, and a $149 one-time lifetime plan. Arthize is a lower-cost alternative to Adobe Acrobat, Smallpdf and iLovePDF for people who want serious PDF tooling without the subscription bloat.

About

Most online PDF tools upload your file to a server to do the work. KeptPDF does the work right in your browser: 25 tools including redact, sign, compress, OCR, organize, and compare. Your document is never part of a single request. The proof takes ten seconds: load the page, turn on Airplane Mode, and every tool still works. Free tier with no account. Pro adds bulk actions, personal redaction lists, and exports for $29/mo. The redaction engine auto-detects names, SSNs, phone numbers, addresses, and dates, removes the underlying text instead of drawing a box over it, and prints an audit certificate on every file that anyone can verify. A command line version runs the same engine on your own servers for bulk work: scanning bureaus, litigation support teams, and records departments process thousands of PDFs in one pass.

KeptPDF is a PDF toolkit that runs entirely in your browser. Nothing uploads: redaction, OCR, compression, signing, splitting, merging, and the rest of its 25 tools all run on your own device, so the document never touches a server. The redaction engine auto-detects names, SSNs, phone numbers, addresses, and dates, removes the underlying text instead of covering it, and prints a verifiable audit certificate on every file. A command line version handles thousands of PDFs in one pass for scanning bureaus, litigation support teams, and records departments. The core tools are free with no sign-up.
