Upload & Fill Any Flat or Scanned PDF with AI Have a flat PDF scan, government permit, vendor packet, or client intake form without clickable fields? JustFill AI automatically detects text boxes, checkboxes, date fields, and signature areas so you can type cleanly on top of the original layout without shifting fonts or pagination. 3. Batch Mail Merge PDFs from Excel or CSV Need to populate 50 or 500 copies of a PDF form from a spreadsheet? Open the Excel/CSV Batch Mail Merge workflow, upload your blank PDF template and .xlsx or .csv file, map columns to PDF fields once, and download all completed PDFs in a single ZIP archive. 4. Make Flat PDFs Fillable & Send Share / E-Sign Links Turn static PDF documents into interactive AcroForm PDFs with fillable text inputs and checkboxes, or generate a hosted Share & E-Sign link (justfill.app/f/...) so clients, employees, or borrowers can complete and sign the form on any phone or computer. 5. Fix "Please Wait..." Adobe LiveCycle / XFA PDFs Unlock restricted government, USCIS, and military XFA PDFs that display the "Please wait... If this message is not eventually replaced by the proper contents of the document" error in standard browser PDF viewers. 6. Free Browser PDF Utilities • PDF Word Search: Search inside PDFs or right-click highlighted text on any webpage to search for that phrase inside a PDF. • Combine PDFs: Merge multiple PDF files into one document in your browser. • Split PDF: Extract specific page ranges from any PDF. • Flatten PDF: Lock fillable form fields and annotations into a permanent, non-editable PDF page layer. RIGHT-CLICK CONTEXT MENU SHORTCUTS • "Open & Fill PDF in JustFill" — Right-click any page or PDF link to open JustFill. • "Batch-Fill PDF from Excel / CSV in JustFill" — Jump straight to spreadsheet-to-PDF mail merge. • "Search PDF for [selected text] in JustFill" — Highlight any term and launch PDF Word Search. PRIVACY-FIRST BY DESIGN This extension uses minimal permissions (contextMenus and local storage for your recent form shortcuts). It never reads your browsing history, never injects scripts into webpages, and never accesses page content in the background.
