About This Tool
JustConvert's PDF editor is being upgraded into a full document editor. It renders pages in the browser with PDF.js, keeps lightweight edits client-side, and uses MuPDF for existing text edits where a normal overlay is not enough.
Existing PDF text can be edited one line at a time. Some PDFs use subsetted fonts that do not contain every new character, so the editor may ask you to use a fallback font. Scanned PDFs need OCR before text editing is available.

Frequently Asked Questions
Can I edit existing text in a PDF? expand_more
Yes, for text-based PDFs the editor supports line-by-line text editing. It does not promise paragraph reflow, and PDFs with subsetted fonts may require a fallback font for new characters.
Can scanned PDFs be edited? expand_more
Scanned PDFs need OCR first because they contain page images rather than selectable text. The OCR workflow detects scanned files and enables text editing after recognition.
Are highlights and notes real PDF annotations? expand_more
The new editor is designed to save highlights, underlines, strikethrough, sticky notes, and links as standard PDF annotations where possible, so Acrobat and other PDF viewers can recognize them.
What is the difference between whiteout and permanent redaction? expand_more
Whiteout visually covers content. Permanent redaction removes the underlying text or image content so it cannot be recovered from selection or copy-paste.
Are my files private? expand_more
Editing runs in the browser wherever possible. Server-side fallbacks use temporary files only, and output files are automatically deleted after the download window.
