Most real PDF edits are small and surgical: fixing a typo, changing a date, updating a price, swapping a name on a template. There are two ways to do them here, both backed by the same detection engine that reads font, size, weight and colour straight from the document and matches it.
For changes larger than a few words, Add Text places fresh text boxes anywhere on the page, and PDF to Word exports a fully reflowable document you can restructure at paragraph scale and re-export. Pick the tool that matches the size of the change.
White-Out covers an area in a colour matched to the surrounding page, which is the reliable way to remove something visually before writing over it. It is a presentation tool — for material that must be genuinely unrecoverable, Redact PDF rebuilds the page without the underlying content.
Draw gives you freehand ink with an adjustable stroke width, for circling a clause, ticking a box, or annotating a drawing. An eraser removes strokes without disturbing the page beneath.
Shapes places rectangles, lines and arrows — the vocabulary of document mark-up, for pointing at the thing you are asking about.
Image drops a logo, a stamp or a photographed signature onto the page at any size and position. Photographs of ink on paper get the same treatment as in Sign PDF: the paper is detected and removed so the ink sits naturally on the document instead of arriving inside a grey box.
Colour applies to every tool, and text sizes run from 8 to 72 points with a custom field for anything in between.
Scanned documents are pictures of text, so click-to-edit needs a real text layer underneath. Scanned pages are detected automatically and a clear banner appears at the top with two one-click routes:
Clicking on a scanned page without running OCR surfaces the same two options as a hint, so you always know which workflow suits the document in front of you.
This is the part that determines whether an edited PDF is still a good document, and it is worth being explicit about.
Edits are written into the file as vector content — real text objects and real drawing operations — not as a flattened picture of the page. So the document you get back is still a document. The text you did not touch stays selectable and searchable with its original fonts. Images keep their exact resolution. Vector artwork stays sharp at any zoom. The file size stays sensible.
The naive approach is to render each edited page to an image and rebuild the PDF from those. It is far easier to implement, and it silently destroys the text layer, breaks search and copy, makes the file unreadable to screen readers, and inflates the size several times over. An edited page here carries no such penalty: save a 40-page contract after fixing one date and you get a 40-page contract with one date fixed.
Edit PDF is the general-purpose option, and several jobs have a more direct route.
Filling in a form with real fields — Fill PDF Form reads the form's own widgets and handles tab order, checkboxes and dropdowns properly.
Adding a signature — Sign PDF gives you a signature library, initials, date stamps and apply-to-all-pages.
Removing sensitive information — Redact PDF deletes the underlying content rather than covering it.
Adding or removing whole pages — Insert Pages and Delete Pages.
Rewriting whole sections — PDF to Word, edit in a word processor, and convert back.
Marking every page — Watermark PDF for a consistent stamp, Add Page Numbers for a sequence.
Yes, two ways. Run OCR first to add a real text layer and click-to-edit then works exactly as it does on a native PDF. Or use the manual route: White-Out covers the original content and Add Text writes new content over it. Scans are detected automatically and both options are surfaced at the top of the page.
Yes. The font name, size, weight, italic flag and colour are read from the PDF itself and applied to your replacement, so an edited word sits in the paragraph without announcing itself. This is what makes single-word corrections practical — the usual giveaway is replacement text in a slightly different face.
The edits become ordinary page content, so the document opens as a normal PDF everywhere. Anyone examining the file's properties can see it was modified and when, which is true of any editor — Edit Metadata lets you review and set those properties before sending.
When a PDF embeds only a subset of a typeface — just the characters the original document used — a replacement containing new characters falls back to the closest available match. It is usually imperceptible in body text. For a heading where it shows, Add Text lets you place the wording exactly as you want it.
Yes. Edits are saved as vector text and drawing operations rather than as a flattened image, so the existing text layer survives intact and your new text is real text too — searchable, selectable and readable by screen readers.
Unlock it first with Protect PDF, make your changes, then re-apply the password with the same tool. Encryption prevents the page content being read, which is what it is for.
It is the most complex tool on the site — live page rendering, font and colour detection per word, in-place text replacement, and a full annotation layer, all in the browser. Every Pro tool includes three free runs per device, so you can edit your own document and see the result before deciding.
No. Rendering, editing and saving all happen inside this browser tab, and the edited file goes straight to your downloads. The contracts and letters people edit stay on their own machine — go offline before you start and it still works.
Privacy: Every edit — the inline text replacements, the whiteout boxes, the shapes you draw — is written locally by pdf-lib. Your document is yours start to finish; no server ever sees the file or the changes.
