Arthize lets software developers fill out a PDF form in a private workspace — free, with no watermark. Filling a PDF form lets you type into fields, tick checkboxes and select options, then save the completed form without printing.

## Why developers fill out a PDF form

A developer converts a Markdown spec to a clean PDF for a stakeholder, extracts text from a vendor PDF to parse it, and archives the release notes as PDF/A.

**Built for technical docs.** Whether it's technical docs, specs, README files, Arthize's fill pdf form keeps the work inside your private workspace. Internal specs and unreleased docs are confidential; a private workspace keeps them off public converters.

## What matters when you fill out a PDF form

You can type into interactive fields and tick checkboxes directly.

Completed forms can be flattened so values are locked.

No printing or scanning is required.
