Sign & edit

Fill it in, sign it, drop a picture on it, delete what should not be there. Your file never leaves this tab.

Signing a PDF normally means uploading it to a stranger, or buying software. This does it in your browser: the page is static, there is no endpoint to send a document to, and you can check the network tab. Turn off your wifi once the page has loaded and everything below still works.

About deleting text, because this one matters.

Drawing a black rectangle over text is not redaction, and it is how governments and law firms have leaked documents for twenty years. The text stays in the file underneath the box — you can select it, search it, or hand the file to a chatbot and ask what the box is hiding. Free tools that offer “black out” almost always do exactly this.

So the delete tool here does not draw anything. Click a word and this finds the actual instruction in the file that drew it, and removes that instruction. The characters stop existing. Nothing is covered, nothing is flattened, and every other word on the page is still real selectable text — you can delete one line out of a contract and the rest of it stays a normal PDF.

That only works when a word can be tied to one instruction. Some documents draw text in ways that cannot be, and rather than guess and cut the wrong sentence, the editor says so and points you at black out instead. That is the blunt fallback: the whole page is rendered to pixels with your boxes painted in and the original page thrown away, so the text really is gone, but the page stops being selectable text and the file gets bigger. Only the pages you black out are affected. If you black out a page, check the preview covers every character — what your box misses is still readable as pixels.

1. Open a PDF

Drop a PDF here, or click to choose Nothing is uploaded — it is opened inside this tab

2. Pick a tool, then click the page

Fill the form — type straight into its fields Add text — click where it goes Signature — click to stamp it Picture — click to place it Delete text — click a word (double-click to replace it) Black out — drag a box (last resort, flattens the page)

Anything you add can be dragged afterwards, resized by its corners, nudged with the arrow keys (hold Shift for ten points at a time), or removed with Delete. Snap to the lines already on the page

Text

Text:

Size: points

Match the size of the text you click next to

Filling in a form: tick that, click on the line, and it comes out the same size as the label beside it.

Signature

Draw it with a mouse or a finger, or type your name and pick a hand.

or type:

Width on the page: points (about 56 mm)

Picture

Choose a picture:

PNG and JPEG go in as they are. Anything else your browser can open — WebP, GIF, BMP — is converted to PNG first, which can make it bigger. Photos keep their full resolution, so a phone photo makes a phone-photo-sized PDF.

Width on the page: points (about 71 mm)

Or place it and drag any corner to size it by eye.

The honest notes

Nothing is uploaded. Static page, no endpoint, no account.
This is not a digital signature. It draws your signature onto the page, exactly like signing a printout and scanning it. It is what almost everyone means by “sign this PDF”, and it is what most people are asked for — but it carries no cryptographic proof of who signed. If you need a certifying signature that Acrobat will validate, you need a certificate, and this is not that.
Deleting is surgical; replacing is not re-flowing. Deleting removes the drawing instruction, so those characters leave the file. Replacing deletes the old and places new text at the same spot and size — which is what you want on a form or a name or a date. What it does not do is re-flow a paragraph: a PDF stores glyphs at positions, not sentences, so if your replacement is much longer than what it replaced it will run past where the old line ended instead of pushing the rest of the paragraph along. Nothing can honestly do that to an arbitrary PDF, and tools that claim to are usually rebuilding your layout and getting it wrong.
Pictures go in at full resolution. A PNG or a JPEG is embedded exactly as it is — nothing is re-compressed behind your back, so a photo straight off a phone makes a PDF the size of a photo straight off a phone. Anything else your browser can open (WebP, GIF, BMP) has to be repainted as a PNG first, which is lossless but throws away the original compression and usually makes it larger. The same picture placed twenty times is still stored once. HEIC from an iPhone will not open: browsers cannot decode it, and this page has nothing else to ask.
Black out flattens the page. Only the pages you black out, and only when the surgical delete cannot safely be used, because covering text does not remove it.
It downloads about 700 KB the first time you open a file — pdf.js to render pages, pdf-lib to write them, plus font metrics for whatever your document uses. All served from this domain, because the security policy here forbids third-party scripts and a page handling your contracts is the wrong place to make an exception.
Large scans use memory. Everything is in the tab, so a 200-page scan may struggle on a phone.

Rearranging pages, merging or splitting is the other PDF tool.
