Fill a PDF Form in Seconds — Right in Your Browser

No upload, no account, no waiting. Open your PDF, fill in the fields, download. Done — and your data never touches a server.

→ Try it free — no sign-up

Most online PDF tools require you to upload your file to a remote server before you can do anything with it. For a tax return, a signed contract, or a medical form, that means handing sensitive data to a third party you know nothing about. iSharePDF works differently: the entire process runs locally in your browser, using the Web APIs built into Chrome and Firefox. Your PDF never leaves your device — not even for a millisecond. You get 5 free tasks per day with no account required, and unlimited access for 4.99 €/month or 39 €/year if you need more.

Why filling your PDF form locally actually matters

How to fill a PDF form with iSharePDF — 5 steps

  1. Open the tool: Go to /app/tools/forms or click the iSharePDF Chrome extension icon in your toolbar.
  2. Load your PDF: Drag and drop your file into the interface, or click "Choose file". The document renders instantly — no upload progress bar, because nothing is sent anywhere.
  3. Click a field and type: Interactive form fields (text boxes, checkboxes, dropdowns, radio buttons) are detected automatically. Click any field and fill it in directly. For flat PDFs with no native fields, use the free-text overlay tool to place text anywhere on the page.
  4. Review your entries: Navigate through pages using the built-in viewer. Edit any field at any time before exporting — changes are non-destructive until you download.
  5. Download the filled PDF: Click "Save PDF". The filled file is generated locally and downloaded straight to your device. No watermark on the free plan for standard form fills.
