Supported Document Types

Unlike most free PDF fillers that only handle interactive forms, JustFill works with every type of PDF document you'll encounter — from scanned paper to complex government filings.

Scanned Paper Documents

Paper forms you've scanned or photographed. JustFill renders the image and lets you draw fields on top. For best results, scan at 300 DPI with a flatbed scanner — phone camera scans work too, but higher resolution means sharper text and more accurate AI field detection.

Flat (Non-Interactive) PDFs

PDFs exported from Word, Excel, or design tools that look like forms but have no built-in fields. This is the most common type — you see blank lines and checkboxes, but clicking them does nothing. JustFill lets you draw fields directly over those blanks.

Interactive AcroForms

PDFs with embedded form fields (text inputs, checkboxes, dropdowns) built with Adobe Acrobat or similar tools. JustFill detects these native fields automatically, so you can start typing right away without drawing anything.

Government & Tax Forms

W-9, W-4, I-9, 1099, state tax returns, DMV applications, passport renewal forms — JustFill handles them all. Many government PDFs are flat or poorly structured, which breaks most free tools. JustFill's manual field drawing works regardless of how the PDF was created.

Insurance & Medical Forms

Health insurance claims, patient intake forms, HIPAA authorization, dental records requests, and disability paperwork. These forms often mix checkboxes, signature lines, and text fields across multiple pages. JustFill lets you work through each page at your own pace.

Legal & Business Documents

Contracts, NDAs, lease agreements, invoices, purchase orders, and vendor registration forms. Save your company details as a template and fill new contracts in seconds instead of retyping the same address and EIN every time.

Complete Guide: Filling a PDF Step by Step

A detailed walkthrough covering everything from preparing your document to downloading a perfectly filled PDF.

1

Preparing and Uploading Your PDF

Start by navigating to the JustFill editor and clicking "Upload PDF" or dragging your file directly onto the page. JustFill accepts PDF files of any size — there's no file size limit on the free tier.

If you're working with a scanned document:

  • Scan at 300 DPI or higher for the sharpest rendering. AI field detection is noticeably more accurate at 300 DPI compared to the typical 150 DPI default on most scanners.
  • Use a flatbed scanner over a phone camera when possible. Phone scans often have perspective distortion and uneven lighting that makes text harder to read.
  • Save as PDF, not JPEG. If your scanner gives you image files, combine them into a single PDF using your OS's built-in print-to-PDF feature before uploading.

If your PDF came from Word, Excel, or Google Docs:

  • These are "flat" PDFs — they look like forms but have no interactive fields. JustFill handles them perfectly. Just upload the file as-is.
  • Avoid password-protected PDFs. If the file requires a password to open, remove the protection first using your PDF viewer's security settings.
2

Adding Fields and Entering Your Data

Manual field drawing (free):

  • Click the "Add Field" button, then click and drag on the PDF to create a text field exactly where you need it. Position it over the blank line, checkbox, or area you want to fill.
  • Resize fields by dragging the corner handles. Make the field large enough to fit your text comfortably — the font size adjusts automatically to fit the field dimensions.
  • Multi-page forms: scroll down to navigate between pages. Fields are page-specific, so you can work through a 20-page document one page at a time without fields from page 1 interfering with page 5.

AI auto-detection (paid plans):

  • Click "Detect Fields" and the AI analyzes the entire document, identifying every fillable area — text lines, checkboxes, date fields, signature blocks, and more.
  • Review the detected fields and adjust any that need repositioning. The AI is accurate on well-structured forms but may need minor tweaks on unusual layouts.

Entering data:

  • Click on any field and start typing. Use Tab to move between fields quickly — this is especially useful on long forms with dozens of fields.
  • Voice dictation (paid): click the microphone icon and speak your data. Supports English, Polish, German, French, and Spanish. Useful when you're filling the same information across multiple forms and don't want to retype it.
3

Downloading and Sharing Your Filled PDF

When you're done filling, click "Download" in the top toolbar. Your filled PDF downloads immediately — no email gate, no waiting queue, no account verification step.

  • No watermarks, ever. The downloaded file is identical to your original PDF with your data rendered directly onto the pages. Recipients can't tell it was filled with JustFill.
  • Original quality preserved. The PDF resolution, fonts, colors, and layout remain exactly as they were. Your filled data appears as native PDF text, not as an image overlay.
  • Save as template: if you'll need to fill this same form type again (monthly reports, recurring invoices, quarterly filings), click "Save Template" to store the field layout. Next time, upload a blank form and load the template — all your fields appear instantly, ready for new data.

Pro tip: before downloading, scroll through every page to double-check your entries. It's easy to miss a field on page 3 of a long form. The field list panel on the left shows all fields across all pages — any empty fields are highlighted so you can spot gaps quickly.
