How to edit a PDF in your browser
Open your PDF
Drag a PDF onto the page, click to browse, or paste from clipboard. The file is parsed locally via PDF.js — nothing is uploaded.
Pick a tool
Add text, draw with the pen, highlight, redact (whiteout), place shapes (rectangle, ellipse, arrow, line), drop an image or paste a signature. The contextual bar adapts to the tool you picked.
Place, drag, resize
Click on the page to drop the element, then drag, resize from any corner, change colour, font size, stroke width — all changes are non-destructive until you save.
Reorder pages & save
Drag thumbnails in the sidebar to reorder, rotate or delete pages, then click Apply & download. Annotations are baked into the page content so they show up in every PDF reader.
About this online PDF editor
This PDF editor online turns your browser into a full-featured editor — add text, draw, redact, sign, insert images and shapes — without uploading the file anywhere. It uses Mozilla's PDF.js to render the document and pdf-lib to write back the edits, so the entire editing pipeline runs in JavaScript on your device.
Add text & edit text
The Add text tool drops an editable text box anywhere on a page. Pick the font family (Helvetica, Times, Courier), font size, colour, bold and italic from the top bar before or after placing — the toolbar appears the moment you select the tool, not only after dropping the text.
Draw, highlight & whiteout
The pen tool records a free-hand stroke with adjustable colour and width. Highlight drops a semi-transparent yellow over a region — non-destructive and perfect for review markup. Whiteout draws an opaque rectangle that hides whatever is underneath; combine with the Text tool to type new content over the whited-out area for a true find-and-replace experience.
Shapes, lines & arrows
Place a rectangle, ellipse, line or arrow. Each shape has fill colour, stroke colour and stroke width controls. Drag handles to resize; hold the corner handle to move; pick a colour from the swatch picker to recolour without redrawing.
Insert images & signatures
Drop a PNG or JPG anywhere — perfect for logos, watermarks or scanned signatures. The Signature tool lets you draw a signature with your finger on mobile (touch-events supported), or upload an image — and place it at any size, anywhere on the page.
Mobile editing
Every drag, resize and draw gesture uses pointer events with setPointerCapture so touch interactions are smooth on iPhone, iPad and Android. The contextual toolbar is sticky at the top below the site header and scrolls horizontally on narrow screens so every control stays reachable on a 375 px-wide phone.
Privacy & what's not editable
Nothing leaves your device — the file never touches a server. The tool edits the page content stream (drawing new objects on top of existing pages) rather than reflowing the original document model — so very fine-grained edits like changing a single word inside an existing paragraph would need to rebuild the original layout from scratch (an Acrobat Pro-grade feature no free in-browser tool ships). For text edits, the easiest path is to whiteout the old text and place new text on top.
