About the PDF Form Field Viewer
The PDF Form Field Viewer lists every fillable field in a PDF form with its type and current value, and lets you fill and save it. It runs as plain JavaScript inside the page, which means there is no upload step, no queue and no size limit imposed by a server — the only limit is your own device.
What people use it for
- Filling a form without Adobe Acrobat.
- Checking what fields a form contains before automating it.
- Flattening a filled form so it cannot be edited.
Frequently asked questions
Is the PDF Form Field Viewer free, or is there a paid tier?
Free, unlimited, and no email address required. You can use it a hundred times a day and nothing changes.
Is my data uploaded anywhere?
No. The PDF Form Field Viewer runs entirely in your browser using JavaScript. Nothing is transmitted, logged or stored, which you can verify yourself in the Network tab of your browser's developer tools.
What problem does the PDF Form Field Viewer solve?
The jobs it is built for: filling a form without Adobe Acrobat. Checking what fields a form contains before automating it. Flattening a filled form so it cannot be edited. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
How large a file can I use?
There is no limit set by us, because your file is never uploaded — the only ceiling is the memory your own browser will give the tab. Very large files simply take longer to process, and a phone will give up sooner than a desktop.
