How to edit a PDF
In short
Open the PDF in the PDF Editor, click any line of text and retype it; the editor matches the original font, size and position. Use Add for new text, images or whiteout, then Review & download writes the changes into the file. If clicking the text does nothing, the PDF is a scan and the OCR PDF tool has to read it first.
PDFs were designed to look identical everywhere, which is exactly what makes them awkward to change: the format stores where each character sits on the page, not paragraphs you can retype. Editing one well means working with that, not against it.
Open PDF EditorEdit text, images and signatures in placeStep by step
Open the document
Drag your PDF onto the PDF Editor. It opens with the existing text already selectable. Nothing is uploaded until you save, so you can look before you commit.
Click the line you want to change
Click directly on any line of text and retype it. The editor matches the original font, size and position, so a small correction stays invisible rather than announcing itself.
Add anything that isn't there yet
Pick a mode at the top and its tools appear in the row below: Add places text, images, shapes and whiteout anywhere on the page, Annotate highlights, and Sign adds your signature. Whiteout covers something you want gone without leaving a gap in the layout.
Check the pages, then save
Delete pages or insert blank ones from Pages at the top. Review & download writes everything into the PDF itself and shows you the finished file before you download it.
If clicking the text does nothing
Your PDF is probably a scan. A photograph of a page rather than a document with real text. There is nothing to click because there is no text layer. The OCR PDF tool handles that case: it recognises the words and rebuilds them as editable text while the original page stays underneath.
Why edited text sometimes looks slightly different
A PDF only embeds the characters it actually uses. If the original used a font that is not embedded in full, a replacement character has to come from somewhere else, and the shapes can differ subtly. Keeping edits short and checking the preview is the practical answer.
Common questions
Can I edit a PDF for free?
Yes. Every tool works without paying, including the full editor. Files can be up to 200 pages and 50 MB.
Do the changes really save into the file?
Yes. Edits are written into the PDF itself with fonts embedded, so the file you download opens correctly in Acrobat, Preview, Chrome and anywhere else, not just in this editor.
Do I need an account?
No. The editor works without signing in. A free account raises your allowance.
