Common use cases

Scanned forms and legacy PDFs

Turn a scanned form or legacy PDF into a fillable version without redesigning it or rebuilding fields in another tool.

Partially completed documents

Send a partially completed PDF and let recipients finish the remaining fields directly on the file. No webform required.

Externally sourced forms

Take a form from a government agency, vendor, or partner and make it fillable in any PDF viewer.

Key benefits

Fill PDFs in any software

Anvil embeds standard PDF form fields into the output. Open the file in Preview, Edge, or Acrobat and type directly, no proprietary software needed.

Add info directly to the PDF

Skip the webform for one-off signers or internal review. Fill fields on the PDF itself, then save, print, or route the completed file wherever it needs to go.

Works with any type of document

Scanned pages, exports from other tools, half-completed forms, government-issued documents: Document AI detects fields regardless of how the source PDF was created.
