PDF Form Visualization API

Start building for free today – no credit card required.

Show an AI agent what a form looks like. Get every page of a PDF form as an image with a numbered box on each field to fill, together with a list that tells which field each number is. The agent sees the form the way a person does and fills the right field, even when the field names say nothing.

Also available as an MCP tool

Claude, ChatGPT, Cursor or your own agent can call visualize-pdf-form directly.

Benefits of our PDF Form Visualization API

A field named Text12 doesn't tell an agent what to enter, but the page does. The agent looks at the image, finds the box next to “Date of birth” and fills its field with our PDF Form Filling API. The numbers follow the reading order, neighbouring boxes get different colors so they stand apart, and fields that a form only shows on demand are marked separately. Read-only fields and buttons stay unmarked, so every number is a field the agent can fill.

Read our API documentation to learn how to visualize PDF form fields.

Multi-language Code Example

curl -X POST https://apdf.io/api/pdf/form/visualize \
  -H "Authorization: Bearer TOKEN" \
  -d file="FILE_URL" \
  -d pages="1"

No-Code AI Form Workflows

Integrate our PDF Form Visualization API with Zapier Webhooks to build AI form workflows without code. Hand the page images to an AI step that decides which answer goes into which field, then fill the form – for the forms that arrive in your inbox, cloud storage or CRM, from hundreds of apps supported by Zapier.

After the API call

Your code made the PDF.
Then it went dark.

Opened, read, re-read, dropped on page 4 — you never see any of it. Share the PDFs you generate through Apdf recipient links, and every signal becomes something you can act on: ping Slack, update the CRM, let an agent follow up. Same account, same API token, one more call.
