Purpose
What does Fill PDF forms do?
Use Fill PDF forms to choose a PDF form, enter field values and save either editable or flattened answers. The form fields and their values stay inside the tab, and flattening is offered when recipients should not edit them. Filozy starts the document engine only after you choose a file, performs the work inside this tab, and creates a new result for you to save. Your selected document, its filename, and its contents are not sent to Filozy.
Who normally uses it?
This guide is useful for people searching, comparing, recognizing, completing, or inspecting document information. The working tool is focused on one outcome: Fill in a form and save it, or bake the answers in for good.
Prepare
Before you start
- Determine whether the document has a text layer or is an image-only scan.
- Keep the original available while checking extracted text, differences, fields, or metadata.
- Treat uncertain recognition and layout results as items to verify rather than final facts.

Review warnings and confidence notes before relying on extracted or compared information.
Check names, dates, totals, identifiers, and form answers against the page itself.
Honest expectations
Limitations and important checks
The result depends on the structure and quality of the source document, so visually inspect the exported file before relying on it.
Browser memory varies by device. Very large or unusually complex PDFs may work better when processed in smaller groups.
