Annotate PDF for journalists

Updated July 2026

Arthize lets journalists and newsrooms annotate a PDF in a private workspace — free, with no watermark. Annotating a PDF adds highlights, comments, shapes and notes on top of the page, so you can mark up a document without changing its text.

Why journalists annotate a PDF

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 annotate pdf keeps the work inside your private workspace. Source protection is paramount; documents must be handled privately and metadata stripped before publishing.

What matters when you annotate a PDF

Annotations sit on top of the page and don't change the underlying text.

You can highlight, comment, draw and add notes.

Annotated files are ideal for review and feedback.
