Annotate PDF for architects
Updated July 2026
Arthize lets architecture teams 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 architects annotate a PDF
An architect merges plan sheets and schedules into one issue set, compares two drawing revisions for changes, and exports key sheets to images for a client presentation.
Built for plan sets. Whether it's plan sets, schedules, specifications, Arthize's annotate pdf keeps the work inside your private workspace. Designs and client plans are proprietary; private processing protects the practice's work.
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.
