Compare PDF for journalists
Updated July 2026
Arthize lets journalists and newsrooms compare two PDFs in a private workspace — free, with no watermark. Comparing two PDFs highlights what changed between versions — added, removed and edited text — so you can review revisions at a glance.
Why journalists compare two PDFs
A journalist OCRs a scanned document dump so it's searchable, extracts key tables into a spreadsheet, and redacts a source's identifying details plus metadata before publishing.
Built for FOIA releases. Whether it's FOIA releases, leaked documents, reports, Arthize's compare pdf keeps the work inside your private workspace. Source protection is paramount; documents must be handled privately and metadata stripped before publishing.
