How it works
Edit a PDF online in five simple steps
No account, no upload queue, no watermark on the way out. Open the file and change it.
- 1
Open your PDF
Drag it onto the page or browse for it. Several at once merge into one working document, every page laid out full-width like paper on a desk.
- 2
Click what is already there
Every line of text and every image is live. Retype a sentence and it is set in the document's own typeface. Bold stays bold, serif stays serif.
- 3
Add what is missing
New text that can match the nearest font automatically, images, highlights, whiteout, stamps. And your signature, drawn once and dropped anywhere.
- 4
Arrange the pages
Drag pages into order, rotate, duplicate, delete, insert blanks, extract a few into their own file, or append another PDF at any point.
- 5
Download the result
One click writes a clean PDF in your browser. Edited pages are sealed so replaced text is gone for good; untouched pages keep their selectable text.

Most projects start as a post and end as a PDF.
Social Magnum runs the front half. Writing once and publishing to 20+ networks from one composer. This editor quietly handles the back half: the contract with one wrong line, the brief missing a signature, the deck that needs two pages pulled. Both are free to start.

The toolkit
Ten tools, one working document
Everything below happens to the same file in the same tab. No hopping between single-purpose sites, re-uploading the same confidential document to each one.
- 1
Edit existing text
Click any line and retype it in the document's own typeface. Family, weight, slant and colour are read from the page and matched.
- 2
Replace images and logos
Any picture on the page can be swapped for a new file or removed, including full-page backgrounds.
- 3
Add new text
Your choice of typeface, size, colour, alignment, line height and background. Or let it match the nearest existing text automatically.
- 4
Sign
Draw your signature once; it lands on the page with a transparent background, sized and placed wherever you drop it.
- 5
Whiteout
A paper-coloured patch for removing a line the quick way. Flattened on export, so the covered words are destroyed rather than hidden.
- 6
Highlight
A translucent marker stroke over anything worth attention, in the colour you pick.
- 7
Redact
The black bar that actually works: the page is rasterised on export, so the text underneath stops existing instead of hiding under a rectangle.
- 8
Stamps, watermarks and page numbers
DRAFT, APPROVED and friends, a watermark across every page, and automatic numbering with the position and format you choose.
- 9
Organise and merge
Reorder by drag, rotate, duplicate, insert blanks, extract selections, and append more PDFs, or images, as pages.
- 10
Compress, convert and metadata
Shrink an image-heavy file, export pages as JPG or PNG, pull the text out as .txt, and set the title and author stored in the file.
Built for everyday paperwork
The same editor, whatever the document is. It reads the file you give it and writes a clean one back.
Contracts & agreements
Fix a date, correct a clause, sign, and send it back. Without chasing anyone for the original file.
Small businesses
Quotes, letterheads and corrected paperwork handled in the browser, without an office-suite subscription.
Students & researchers
Merge readings into one file, extract the chapters that matter, highlight as you go.
HR & operations
Forms filled and assembled, and sensitive lines redacted in a way that survives copy-paste.

Files this private should never leave your machine
The parser, the renderer and the writer all run inside this tab. A contract, a bank statement or a medical letter is opened, edited and rebuilt without a byte reaching a server. Switch off your Wi-Fi mid-edit and nothing changes. That is not a privacy policy; it is the absence of servers.
FAQ about editing PDFs
Can I edit the text that is already in the PDF?
Yes. Every line of text on the page is clickable. Change the words, the size, the colour or the typeface, and existing images and logos can be replaced or removed the same way. The editor reads the real font of whatever you clicked and matches its family, weight and slant, so bold stays bold and italic stays italic. Clicking a line only to look at it changes nothing; a page is only rewritten once you actually alter something.
Is my PDF uploaded to a server?
No. The file is opened, edited and written entirely inside this page. The parser and the writer both run in your browser. Nothing is transmitted, which is why the editor keeps working with your network disconnected, and why you can safely put a contract or a bank statement through it.
Why does an edited page stop being selectable?
Because that is the only way to genuinely replace text in a PDF from a browser. Covering a name with a white rectangle leaves the original name in the file, one Ctrl+F away. Worse than useless if the document is private. Flattening the page destroys the old text for real; the words you typed are then drawn back on top in the document's own typeface. Pages you did not touch keep their full selectable text.
Does redaction really remove the text?
Yes, and this is worth understanding because most tools get it wrong. A black box drawn over words hides them visually while the characters stay in the file, where anyone can select, copy or search them. That is exactly how redacted documents leak. Any page you redact here is flattened on export, so the text underneath genuinely stops existing. The trade-off is that the page is no longer selectable, and the editor says so before you download.
How do I merge two PDFs?
Open the first one, then press “Add files” and choose the rest. Or drag several onto the page at once. Their pages are appended in order, you can drag any page anywhere, and images can be added as pages too. Download when the order looks right.
How do I split a PDF or pull out a few pages?
Tick the pages you want in the Pages panel and use “Extract”. You get a new PDF containing just those pages, while the document you are working on stays untouched. So you can pull several different sets out of one file in a row.
Can I open a password-protected PDF?
Yes. You will be asked for the password, and it is used in this tab only. What the tool deliberately cannot do is add a password to the output: the PDF writer used here has no encryption support, and pretending otherwise would hand you a file you believed was protected when it was not.
Can it read the text in a scanned document?
No. That needs OCR, and an OCR model is far too large to sensibly ship to a browser. If text extraction finds nothing, your PDF is a photograph of a document rather than a document; you can still whiteout, stamp, sign and annotate on top of it, but retyping its printed words needs an OCR tool first. The editor tells you plainly instead of returning an empty file.
