SimplePDF - PDF Editor

Edit and fill PDF documents directly in the browser. Add text, signatures, checkboxes, images, and more.

From a URL

For public PDF URLs, use GET with the URL as a query parameter:

GET https://agents.simplepdf.com?url=https://example.com/form.pdf

For signed or sensitive URLs (e.g. presigned S3 links), use POST with a JSON body to keep the URL out of logs and browser history:

curl -X POST https://agents.simplepdf.com \
  -H "Content-Type: application/json" \
  -d '{"url": "https://s3.amazonaws.com/bucket/doc.pdf?X-Amz-Signature=..."}'

Both return JSON with the editor URL and embed snippets.

From a file

Upload a PDF file to the API. For security and privacy, the file is stored temporarily (24 hours) then automatically deleted. The user has 24 hours to open the link. Once opened, the PDF is loaded into the browser and processed entirely client-side, so the tab can stay open indefinitely.

Shell

curl -X POST https://agents.simplepdf.com -F [email protected]

TypeScript

const form = new FormData();
form.append("file", new Blob([pdfBytes], { type: "application/pdf" }), "document.pdf");

const response = await fetch("https://agents.simplepdf.com", { method: "POST", body: form });
const { url } = await response.json();

Python

import requests

with open("document.pdf", "rb") as f:
    response = requests.post("https://agents.simplepdf.com", files={"file": f})

url = response.json()["url"]

Presenting the result to the user

Always present the url field as a clickable link. This is the primary way users will open the editor.

If you have access to a browser automation tool (e.g. agent-browser, Playwright, chrome-devtools MCP server), offer to open the url directly so the user can edit the PDF without leaving the conversation.

The iframe and react fields are for developers embedding the editor in a web application. Only present these when the user is building a web app.
