Edit a PDF without uploading it anywhere.
Drop a PDF and mark it up: notes and highlights, text anywhere, your signature and initials, pages added, deleted, reordered or merged, and your company title and logo across the top. Every one of those happens inside this browser tab — the file is never sent to us or to anyone else.

Everything you can do to it
Write on it
Type anywhere on the page — a date, a name, a missing dimension, a whole paragraph. Pick the size, the colour and left, centre or right.
Notes and highlights
Yellow highlighter over a line you disagree with, a sticky note beside it. A note can be a solid sticky, a tinted one you can read through, or no background at all — just the words on the page. Notes are also written in as real PDF comments, so they show up in the comment list in Acrobat or Preview.
Sign and initial
Draw it with a mouse, trackpad or finger; type it and pick a handwriting; or upload a photo of your signature and the white paper is keyed out. Saved on your own device for next time.
Your letterhead
Company name, a line under it, a contact line and your logo — placed across the top of the first page or every page. Stored on this device, so the next document takes one click.
Add and delete pages
Delete a page, duplicate one, rotate a sideways scan, drag pages into a new order, or slip a blank sheet in between two pages — anywhere in the document, not just at the end.
Merge and split
Drop a second PDF on the page to join them end to end. Split the other way too: one file per page, a cut after page 6, or your own ranges like 1-3, 4, 5-8 — several files come down as a single .zip.
Stamps and watermarks
APPROVED, REVIEWED, DRAFT, FOR CONSTRUCTION — with today’s date under it if you want. Or a diagonal watermark down every page.
White-out and redact
Cover a price, a name or an address with a white or black box. Save with “flatten” on and the text underneath is genuinely gone, not just hidden.
Mark up a drawing
Pen, straight lines, arrows, boxes, circles, checkmarks and crosses — for a floor plan, an elevation or a delivery note.
Find it, then act on every match
Search the whole document for a word, jump between the matches, and then highlight, strike through or black out every single one in a click. That is how a name or a price disappears from a twenty-page contract without hunting for it.
Export as images, or shrink it
Save the pages as JPG or PNG — one file, or a .zip of the lot. Or re-render a heavy scan at a lower resolution to make it small enough to email; the new size is measured and shown before anything downloads.
Fill the form, number the pages
Type straight into a PDF’s own fillable fields and lock the answers in. Stamp a running number on every page — plain pagination, or a Bates prefix for a legal set. Add bookmarks so a long drawing set opens where it should.
Compare two versions
Load the revised quote next to this one and every changed area is boxed on the page. Save the signature, stamp and letterhead you just placed as a set, and drop the whole lot on the next document in one click.
How to use it
- Drop the file on this page. Or press the button and choose it. Nothing is uploaded — the PDF is opened by code running in your own browser.
- Pick a tool and click the page. The toolbar runs along the top. Click once to place a note or a checkmark, drag to draw a highlight, a box or a line. Everything can be moved, resized and restyled afterwards.
- Sign it, stamp it, brand it. Sign opens the signature pad. Stamp drops an APPROVED or DRAFT block. Letterhead puts your logo and company name across the top.
- Sort the pages. The strip on the left is every page: tick them, drag them into order, rotate them, delete them, or click the + in any gap to slip a blank sheet, an image or another PDF in between two pages.
- Download. Download PDF writes the new file straight to your downloads folder. Turn on “flatten” if you covered something and want it truly removed.
Who it is for, and the honest limits
A homeowner signing a kitchen quote without owning Acrobat. A contractor red-lining an elevation before the shop cuts it. A dealer stamping APPROVED on a change order and mailing it back. Anyone who has been asked to “sign and return” and does not want to print, sign, photograph and email a crooked photo of a page — or to upload a contract with prices and an address to a website they have never heard of.
What it does not do. It does not rewrite the text that is already in the PDF — a PDF is a printed page, not a document you can retype, and any tool that claims otherwise is guessing at your fonts. Cover it and type over it instead. It cannot open a password-protected file; remove the password in the program that made it first. Interactive form fields are kept exactly as they look, but they stop being fillable once the file has been through here.

Questions
Is my PDF uploaded anywhere?
No. The file is opened, drawn and saved entirely inside your browser tab. It is never sent to our servers and we never see it. Once this page has loaded you can disconnect from the internet and the editor keeps working.
Is it really free?
Yes. No account, no sign-in, no trial, no watermark on the file you download, and no cap on pages or on how many documents you edit.
Can I sign a PDF here?
Yes, three ways: draw the signature with your mouse, trackpad or finger; type your name and choose a handwriting; or upload a photo or scan of a signature you have already made on paper — the white background is removed automatically. Signatures and initials are saved on your own device so the next document takes one click. This is a visible signature on the page, not a cryptographic digital signature.
Can I edit the text that is already in the PDF?
Not directly, and no honest browser tool can. A PDF stores glyphs at fixed positions with fonts that are often subset and unnamed, so “editing” it means guessing. What works reliably is covering the old text with a white box and typing the new text on top — the white-out and text tools do exactly that, and the result prints identically.
Can I merge two PDFs, or delete a page?
Yes. Drag a second PDF onto the page area and it is added to the end; the page strip on the left lets you delete, duplicate, rotate and drag pages into any order, insert blank sheets, or tick a few pages and save only those as a new file.
How do I find and black out a word everywhere it appears?
Press Find, type the word, and the matches light up across the whole document. Then one button blacks out every one of them. Tick "flatten to images" when you download and the text under the boxes is genuinely removed, not merely covered.
Can I turn a PDF into JPG or PNG images?
Yes. More → Export images saves the pages as JPG or PNG at screen, good or print resolution. One page comes down as a single image; several arrive as a .zip.
How do I make a PDF smaller?
More → Reduce size re-renders every page as an image at a resolution you choose. It shrinks a photographed or scanned document a great deal; it will make a plain text document larger, so the tool measures the result and shows you both sizes before anything is downloaded.
Can I fill in a PDF form?
If the PDF has real fillable fields, More → Form lists them and you type your answers in. Locking them in is the default, so they print and display everywhere. If the file has no fields, use the Text tool to type on it instead.
How do I split a PDF into separate files?
Press Split. You can cut every page into its own file, cut the document in two after a page you choose, give your own ranges such as 1-3, 4, 5-8, or export just the pages you have ticked in the page strip. If that makes more than one file they come down together as a single .zip.
Does the white-out box really remove what is underneath?
Only if you flatten. By default the box is drawn over the text, which still exists in the file and can be copied out. Tick “flatten to images” when you download and every page is re-rendered as a picture: the text layer is gone, the redaction is real. The file gets larger and the text is no longer selectable, which is the point.
What about password-protected PDFs?
They cannot be edited here. Open the file in whatever program made it, save a copy without the password, and use that. This is deliberate: writing to an encrypted file without the key produces a corrupt document.
Will the fillable form fields still work?
The fields are preserved exactly as they look, including whatever is already typed in them, but they are no longer interactive after the file has been edited here. Fill the form first, then bring it here to sign and stamp.
Which browsers does it work in?
Any current version of Chrome, Edge, Safari or Firefox, on a computer, a tablet or a phone. On a tablet you can sign with a finger or a stylus. There is nothing to install.
How big a file can it handle?
It is limited by your device’s memory rather than by us. Ordinary quotes, contracts and drawings — even a few hundred pages — are fine. A very large scan of hundreds of photographed pages will get slow, because every page is being rendered on your own machine.
