Open the tool in your browser, drop the file in, type what you want stamped, tweak how it looks, and grab the finished file. Nothing sits on your hard drive. The whole thing runs right there on the page.

Yeah, the tool lets you type words and drop in a PNG or JPEG at the same time. Both show up together on every page. You get to pick the size and how see-through each one looks.

PNG, JPEG, and SVG all work fine. If you have a logo with no background, go with PNG. The tool stuffs the image straight into the PDF so it stays put.

There is a slider for that. Slide it down low, somewhere around 0.2 or 0.3, and the mark gets light enough to see through. The little preview window shows the change right away so you know what you are getting.

Yep. Just type a number into the rotation box. Most people go with 45 and it slants the text corner to corner. Looks clean and covers more of the page that way.

There is a little color dot you click on. A panel pops open and you grab whatever shade fits. Red catches attention for urgent stuff, gray stays quiet, black works for formal papers.

It stamps every page in the file. If you only need it on a few pages, split those out first, mark them up, and put the document back together after.

Two little number boxes control where it sits. One shifts it side to side, the other moves it up and down. The preview changes as you tap the numbers so you see where it lands.

It uses Helvetica, which gets baked right into the file. You cannot swap fonts, but you can change the size from tiny to huge. The text stays sharp no matter what device opens it later.

Most of the time files up to 100MB load fine. Really heavy ones with tons of pictures might take a moment longer. The work happens on your device so your internet speed does not matter much.

Nope. Everything underneath stays exactly the same. The text stays clear, pictures keep their quality. The mark just sits on top like a new layer. File size goes up a tiny bit but nothing crazy.

Yes, a preview box sits right there in the tool and updates every time you change something. You see exactly how the mark sits on a sample page before you commit to downloading anything.

Pretty much. It gets built into the pages when the file saves. Nobody can just click and delete it like a sticker. Hang onto a clean copy of the original if you think you might need it later.

Nope. No accounts, no credit cards, no email needed. You open the page, follow three steps, and download your file. That is the whole deal.

Works fine on a phone or tablet. The page adjusts to whatever screen you are holding. You upload, type your watermark text, tweak the look, and download, all from a mobile browser. No app needed.

Everything disappears. The tool does not save your file or settings anywhere. You would need to start fresh. So grab your download as soon as the watermark looks right.

Nah, it only adds them. Removing an old watermark needs a different kind of editor. This is why keeping a backup without any marks is a good habit before you stamp anything.

Just to load the page at first. After that the watermark work happens right on your device. Your file never leaves your computer. You could even go offline after the page opens and it still works.

Stuff like "Confidential," "Draft," "Attorney Review," or a case number works. The text box holds up to 70 characters. Just pick words that make the status obvious the second someone opens the file.

One at a time. But since there is no waiting around or signup screens, you can zip through several files pretty fast. Just repeat the three steps for each document.
