Guide
What actually happens when you edit a PDF here
Edit PDF actually runs two different engines depending on what you're touching. Switch to Edit mode and the app pulls real text runs out of the page — the same text-showing operators that give PDF.js a selectable text layer — and lets you click one and retype it. That request goes to an iText7-backed endpoint that covers the original run with a size-matched rectangle and redraws your replacement in the nearest available font, so the fix looks native instead of stapled on.
Stay in Annotate mode and you get a different toolkit built for marking up a page rather than rewriting it: freehand drawing and a wider highlighter stroke, four shape types (line, rectangle, circle, arrow), click-to-place sticky notes and rubber-stamp text, a signature pad that exports your drawn signature as a placeable image, and text-range markup — highlight, underline, strikethrough, squiggly — that reads your actual selection instead of a hand-drawn box. A drag-to-cover redact tool is in the same set, though it paints over content rather than stripping it from the file.
Both modes work page by page against thumbnails rendered straight from the PDF.js canvas, so you can jump to page 30 of a long contract without the tool reflowing anything around it. Whichever mode you finish in, the export step serializes only what changed — edited text runs, or the batch of annotation objects — and sends that back to be written into the specific pages you touched.
Retype text without rebuilding the layout
Click a sentence in Edit mode and PDF.js hands back the exact text run under your cursor. Retype it and the change routes to an iText7 pass that masks the original glyph run with a size-matched rectangle and redraws the replacement in the closest font, weight, and size — the rest of the page's content stream is untouched.
One annotation canvas, not five separate tools
Freehand drawing, a highlighter with its own stroke width, click-to-place sticky notes and stamps, four shape types, and image drops all live on the same page overlay, so you don't bounce between a markup tool and a shape tool to finish one page.
Markup that follows your text selection
Highlight, underline, strikethrough, and squiggly aren't drawn boxes you eyeball into place — you select the actual words on the page and the tool reads the selection's bounding rect from the text layer, so the mark lands exactly on the characters you picked.
Signatures placed as movable, resizable objects
Draw a signature on the canvas pad and it exports as a PNG that becomes a normal image annotation — drag it, resize it, or delete it before you commit, instead of it being burned in the moment you draw it.
Common uses
Where people use this
Fix a wrong date, name, or dollar figure on a born-digital invoice or letter before resending it, without recreating the whole document.
Redline a contract draft with highlight, strikethrough, and sticky notes before it goes to outside counsel for review.
Drop a drawn signature and the day's date onto a one-off form or waiver that doesn't justify setting up a full e-signature workflow.
Mark up scanned meeting handouts or diagrams with arrows, shapes, and stamps since Annotate mode works on image-only pages too.
Insert a missing clause number or initial box as a text annotation on a page you can't regenerate from the original source file.

FAQ
Frequently asked questions
?When I retype a sentence, is it really editing the PDF or just pasting a box over it?
Functionally it's a cover-and-redraw: the server finds the original text run's coordinates, paints a white rectangle sized to match its width and height plus a few points of padding, then writes your new text in a font resolved to the closest match for the requested family, size, and bold/italic state. Visually it reads as edited text because the rectangle is pixel-matched to the run it replaces — but the original glyphs are covered, not deleted from the content stream.
?Does the redact tool actually strip the covered text from the file?
No — redact in Annotate mode drags out a solid black rectangle on the canvas, and on export that rectangle is flattened into the page like any other annotation. It reliably hides content visually, but it doesn't guarantee the underlying text run is removed from the PDF's object structure. If you need certainty that sensitive text is gone from the file itself (not just covered on screen), don't rely on this tool for that call.
?Why can't I click on text to edit a scanned PDF?
Edit mode extracts editable blocks from the PDF's real text-showing operators — the same data PDF.js uses to build a selectable text layer. A scanned page is one big image XObject with no text runs behind it, so there's nothing for the extractor to find. Annotate mode still works on scans since it only adds new content on top; it just can't offer existing text to retype.
?Will the retyped text match the original font exactly?
It approximates rather than guarantees a byte-identical match. The server maps your chosen font name plus bold/italic flags to the closest available font program, since most PDFs embed subsetted fonts that can’t be reproduced from a name alone. On documents where exact typeface fidelity matters — branded templates, filed legal forms — check the exported page before sending it out.
?What happens to my drawn signature after I place it?
The signature pad exports your stroke as a PNG, which becomes an image annotation you can still drag or resize on the canvas. Nothing is committed to the actual PDF bytes until you save — at that point every annotation on the page, including the signature image, gets serialized and sent to the server in one batch to be drawn into the page.
?If I only edit page 6 of a 40-page contract, does anything change on the other 39 pages?
No. Both the text-edit pass and the annotation-flatten pass operate on individual pages identified by page number and PDF-space coordinates — a page you never touch is copied through with its content stream exactly as it was in the upload.
