Free Online Edit PDF: Edit a PDF online
Open a PDF, recognize existing text with embedded PDF metadata or OCR, edit the detected text and formatting in place, then download a new edited PDF. It is also useful for editing PDF when you want the same task handled in one straightforward browser workflow.
Recognize existing PDF text before editing
DOC321 reads embedded PDF text objects first because they carry the most accurate position, font metadata and font size. Scanned pages automatically fall back to high-resolution OCR.
Edit recognized text in place
Click any detected text region directly on the PDF page, change the wording, font family, font size, weight, italic styling or text color, and review the result against the original page.
Keep page geometry while creating an edited copy
Text regions remain anchored to their original page coordinates. DOC321 covers the replaced visual text and writes the edited version into a new PDF while leaving the source file unchanged.

FAQs About Edit PDF
Can I edit text already inside a PDF?
Yes. DOC321 detects existing text and turns recognized text regions into editable fields on top of the original page. Digital PDFs use their embedded text metadata; scanned PDFs use OCR.
Can DOC321 recognize the original font and size?
For digital PDFs, DOC321 uses the PDF text metadata and font transform for the highest available fidelity. For scanned pages, OCR can estimate text size, position and color, while font family and some styling remain visual estimates that you can correct before export.
Does the tool change my original PDF?
No. It creates a new edited PDF and leaves the selected source file unchanged.
