HonestPDF introduces a fully client-side Fill PDF tool in this update, supporting AcroForm field detection, custom text placement, signature insertion, and undo/redo history across 20 languages.

TL;DR

The new Fill PDF tool lets users complete PDF forms, add freeform text, and sign documents directly in the browser. It handles both structured AcroForm PDFs and unstructured flat documents, with a responsive UI built for desktop and mobile.

What's New

  • Fill PDF tool: Complete AcroForm fields or place custom text and signatures on any PDF
  • AcroForm and flat mode support: Detects and renders existing form fields; falls back to flat overlay mode for non-form PDFs
  • Draggable editor items: Text blocks and signatures can be repositioned freely on the page
  • Floating toolbar: Contextual controls appear near the selected item for fast editing
  • Undo/redo history: Full action history so edits are non-destructive until export
  • Responsive layout: 3-column editor panel on desktop, collapsible bottom sheet on mobile
  • Dark mode support: Editor respects the user's system or site-level theme preference
  • 20 language translations: All new UI strings are fully localized across every supported locale
  • Sitemap and navigation updated: Fill PDF is now linked from the header, footer, and related tools sections

How to Use

  1. Open HonestPDF and select the Fill PDF tool
  2. Upload your PDF. AcroForm fields are detected and rendered automatically
  3. Click any field to fill it, or use the toolbar to add a text block or signature anywhere on the page
  4. Drag items to reposition. Use undo/redo to correct mistakes
  5. Export the completed PDF when done. Nothing leaves your device

FAQ

Does this work with PDFs that have no fillable fields?

Yes. Flat mode lets you drop text and signatures on top of any PDF regardless of whether it was built with AcroForm fields.

Are files uploaded to a server during editing?

No. The entire tool runs client-side. Your PDF bytes never leave your browser.

Is the tool available in my language?

All 20 languages supported by HonestPDF are fully translated for this tool, including the editor UI, tooltips, and export controls.

Does undo/redo work across all edit types?

Yes. The undo/redo history tracks all actions including text input, item placement, repositioning, and signature insertion.
