Free PDF Editor Online

A PDF editor is a tool that changes a PDF after it was created, such as adding text, highlights, shapes, or a signature and filling form fields. This one runs entirely in your browser, so you can edit a PDF online without uploading it or creating an account.

PDF editor workspace

Step 1

Open a PDF to edit

Private browser editing

Your PDF is opened, edited, and saved on this device. It is never uploaded to Code Card, and no account is needed.

  • Add text, highlights, rectangles, and a drawn or typed signature.
  • Fill existing AcroForm text fields and checkboxes.
  • Move, resize, undo, redo, then download a new PDF.
  • Existing paragraph text is not rewritten, and scanned pages are not OCRed.

How to edit a PDF

  1. 1

    Upload a PDF

    Drop a PDF into the editor or choose a file. It opens in your browser and is never uploaded.

  2. 2

    Add your edits

    Choose Text, Highlight, Shape, or Sign, then tap the page to place items. Drag, resize, or nudge them into position.

  3. 3

    Fill form fields (optional)

    Type into the detected AcroForm text fields and tick checkboxes. Values are saved into the PDF form.

  4. 4

    Download the edited PDF

    Select Download edited PDF to save a new copy with every original page and your changes.

What this editor can and cannot do

  • Adds overlays: text, highlights, outline or filled rectangles, and signatures are drawn onto the page at the exact spot you place them.
  • Fills forms: supported AcroForm text fields and checkboxes are saved into the PDF and stay editable in other PDF apps.
  • Keeps your pages: every original page, its size, and its rotation are preserved.
  • Does not rewrite text: existing paragraphs cannot be edited, scanned documents are not OCRed, and a filled rectangle hides content visually but is not a secure redaction.
