To edit a PDF online for free, open the LyfPDF editor and drop in your file. Click any text to change it, use Add text or Image to place new content, switch to Annotate, Forms, Pages or Sign for other edits, then download the edited PDF. There is no login and the file stays on your device.

Edit text in a PDF

  1. Open the PDF editor and choose the PDF.
  2. Click the text you want to change — font, size and colour are matched automatically.
  3. Type the new words; Enter adds a line and Esc cancels.
  4. Click outside the box when you are done.
  5. Click Download PDF. The old text is removed and the new text is saved as real, searchable text.

Other edits you can make

  • Images: insert a logo or photo, or select an existing image to move, resize, crop, replace or delete it.
  • Annotate: highlight, underline, sticky notes, stamps, shapes and freehand pen.
  • Forms: fill fields, add text boxes and checkboxes, and flatten the result.
  • Pages: reorder, rotate, delete, insert, crop and resize pages.
  • Protect: redact, watermark, page numbers and header/footer.
  • Sign: draw, type or upload a signature with date and initials.

Editing scanned PDFs

Scans contain pictures of text. Use the OCR option on the page so the lines become editable, or extract the text with OCR and rebuild the document.

Free vs paid editors

A free browser editor handles everyday edits. Paid desktop suites add batch processing, certified redaction, preflight and document management — see free vs paid PDF editors.
