Rewrite a paragraph inside the document, sign it, redact what should never have been in there, reorder the pages and fill the form — all on your own machine, with nothing uploaded. Install it once and it keeps working offline.
Free · No account · No upload · Works offline
All of it running in a browser tab — or in an installed app window, with no connection.
Click a paragraph and type. The editor rebuilds the paragraph from the glyphs in the file, samples the ink and paper colours, matches the font family, weight and size, and re-typesets your replacement with real word wrapping — not a white box with new text dropped on top.
Select text on the page to highlight, underline or strike it through, drop sticky notes that travel as real PDF comments, and add text boxes, arrows, rectangles, ellipses and freehand ink with full colour and opacity control.
Draw a signature with a trackpad or finger, or type one in a handwriting face. Place it at any size on any page, and add APPROVED, DRAFT, CONFIDENTIAL or PAID stamps where they belong.
Drag over anything private. Pages with a redaction are re-rendered on save, so the words under the black box are gone from the file — not hidden behind a rectangle that anyone can select around.
Drag thumbnails to reorder, select several pages at once, rotate, duplicate, delete, insert blank pages, merge another PDF in or extract a selection into a new file. Deleted pages are genuinely dropped from the output.
Interactive form fields become real inputs — text, checkboxes, radio buttons, dropdowns — and their values are written back into the form on save, so it stays a form rather than a picture of one.
Full-text search with hit highlighting, the document's own outline in the sidebar, and a viewer that only renders the pages near you, so a few hundred pages stay responsive.
Install it from the browser and it gets its own window, a dock or taskbar icon, and opens PDF files directly. No account, no subscription, no multi-gigabyte installer — and it still works with the network off.
There is no upload endpoint. Parsing, rendering and writing all happen on your device, and your working document is kept in your own browser storage so a reload never costs you anything.
Three steps, no account, nothing to install unless you want to.
Drag the file onto the editor or click Open. It is read on your own device — there is no upload, and password-protected files are unlocked locally.
Edit a paragraph, highlight a sentence, drop a signature, fill a field, drag pages into a new order. Every change is undoable.
Choose to keep the file fully vector, remove the text you replaced, or flatten every page — then write it straight back to disk.
Most "online PDF editors" do one of two things: they upload your file to a server, or they let you draw on top of it and call that editing. This one does neither. The PDF is parsed in your browser, rendered on your own machine, and written back out by the same code — and when you edit a paragraph, it edits that paragraph.
A PDF has no paragraphs. It has glyphs at coordinates, in fonts that are often subset and renamed, on a page that may be rotated. To make a sentence editable, the editor groups those glyphs back into lines, and lines into paragraphs, using baselines, spacing and font size. Then it looks at the pixels: the most common colour under the paragraph is the paper, and the colour furthest from it is the ink — which is why this works on coloured backgrounds and inside tinted table cells, not just on white. The original face is mapped to the closest standard PDF font, your replacement is typeset with the exact metrics that will be used in the saved file, and word wrapping happens with those same metrics, so what you see is what lands on disk.
When you save, you choose how the file is written. Keeping everything vector gives the smallest, sharpest file, but the replaced words stay in the document underneath the patch, invisible yet recoverable. Removing replaced text re-renders only the pages you edited, so the old wording is physically gone while every other page stays untouched. Flattening does that to the whole document. Most editors never tell you this distinction exists; here it is a choice you make with both consequences spelled out.
| Task | BrowserCrunch | Notes |
|---|---|---|
| Edit existing paragraphs | Yes | Font, size, colour and background matched automatically |
| Add text, images, signatures | Yes | Vector text and embedded images at full quality |
| Highlight, underline, comments | Yes | Snaps to the real text selection on the page |
| Redact permanently | Yes | Affected pages are re-rendered so content cannot be recovered |
| Merge, split, reorder, rotate | Yes | Including extracting a selection into a new PDF |
| Fill AcroForm fields | Yes | Values written back into the form itself |
| Works offline, installs | Yes | Progressive Web App with PDF file handling |
| OCR of scanned paper | No | Text has to exist in the file to be edited |
| Certificate-based signatures | No | Signatures here are visible, not cryptographic |
| Prepress and PDF/A workflows | No | Colour separation and archival validation need a print suite |
Contracts, payslips, medical letters, tax returns and NDAs are exactly the documents people drop into free web tools without thinking about where the file goes. Because everything here is local, that question does not arise: there is no server to trust, no retention policy to read, and nothing to delete afterwards. It also means the editor works on a locked-down work laptop where you cannot install software, and on a plane where nothing installs at all.
Install it and you get a real application window with a dock or taskbar icon, PDF files that open straight into it, and full editing with no connection. There is no account, no watermark, no page limit and no trial that expires. The PDF engine is served from this site rather than a third-party CDN, so an installed copy keeps working even if the rest of the web is unreachable.
Anyone who needs to fix a typo in a contract they did not write, sign and return a form, black out a salary before forwarding a letter, merge scans into one file, mark up a draft for someone else, or pull three pages out of a fifty-page report — without a subscription and without handing the document to a stranger's server.
Yes. Click a paragraph with the Edit text tool and type. The editor reconstructs the paragraph from the glyphs in the file, samples the colour of the text and of the paper behind it, matches the font family, weight and size, then re-typesets your replacement in place with proper word wrapping.
No. There is no upload endpoint. The file is parsed and rendered on your own device, and the edited copy is written by your browser. Close the tab and nothing remains anywhere but your disk.
For the everyday work most people open Acrobat for — fixing a typo, filling and signing a contract, redacting a salary, merging and reordering pages, adding comments, exporting a page as an image — yes, and it costs nothing. It does not do OCR of scanned paper, PDF/A validation, prepress colour management or digital certificate signatures.
Yes. Pages containing a redaction are re-rendered before saving, so the words underneath the black box are physically gone from the file rather than merely covered. Copying, searching or parsing the saved PDF cannot bring them back.
Yes. It is a Progressive Web App: it installs from the browser into its own window with a dock or taskbar icon, opens .pdf files directly once installed, and keeps working with no internet connection. In Chrome or Edge use the install button on this page; in Safari on macOS choose File then Add to Dock.
Yes. A service worker caches the application after your first visit, so the editor keeps working with no connection — including the PDF engine, which is served from this site rather than a CDN.
Yes. Interactive AcroForm fields appear as real inputs on the page: text fields, checkboxes, radio buttons and dropdowns. The values are written back into the form on save, so the document stays a form rather than becoming a picture of one.
Yes. Draw your signature with a mouse, trackpad or finger, or type it in a handwriting face, then place and scale it anywhere in the document. This is a visible signature, not a cryptographic certificate signature.
The editor maps the original face to the closest standard PDF font — Helvetica, Times or Courier, with bold and italic — and keeps the size, colour and alignment. For text outside the Latin-1 range it embeds a Unicode font automatically. On a heavily branded document a substituted face can differ slightly, and you can change family, size and colour by hand.
Yes. Drag thumbnails to reorder, select several at once, rotate, duplicate, delete, insert blank pages, merge another PDF in, or extract a selection into a new file. Deleted pages are genuinely removed from the saved document.
Documents of several hundred pages work well because only the pages near the viewport are rendered. The practical limit is your device's memory; very large scanned files are the heaviest case.
Yes. The layout adapts to small screens and it installs to the home screen. Annotating, signing and filling forms work well with touch; long editing sessions are more comfortable on a larger screen.
The document and everything you have done to it are stored locally in your browser, so reopening the editor restores your session. That storage never leaves the device, and closing the document clears it.
