Stamp every slide with DRAFT, CONFIDENTIAL, or whatever text you need. Takes about 10 seconds.
or click to browse (.pptx, max 50 MB)
Drag your .pptx onto the box, or click to pick one from your computer.
CONFIDENTIAL, DRAFT, your name, your client's name. Whatever fits.
Font size, opacity, and where it goes. Diagonal is the default and it's usually right.
Hit Add Watermark. Your new file is ready in a few seconds.
Yep. The watermark goes in as a regular shape on each slide. Open the file in PowerPoint, click the watermark, hit delete. Repeat on each slide, or use the Selection Pane to nuke them faster. Smart move though: keep a copy of the original clean file somewhere, just in case.
No. The watermark sits on its own layer on top. Your text, images, charts, animations, speaker notes, all of it stays exactly how you left it.
Not yet. Right now it's gray text because gray plays nicely with almost any slide background. You can tweak opacity to make it subtle or in-your-face. Custom fonts and colors are on the list.
This one's text only. If you want a logo stamped on every slide, the fastest way is to drop it onto your Slide Master in PowerPoint (View > Slide Master), then it shows up on every slide automatically.
Pretty much. Anything from PowerPoint 2007 onwards works fine. Old .ppt files don't, so open those in PowerPoint first and save them as .pptx. Keynote exports and Google Slides downloads in .pptx format also work.
It's how see-through the watermark is. 10-20% is ghost-like, barely there. 70-90% is loud and blocky. 30% (the default) is the sweet spot for most decks, visible without fighting your content for attention.
Diagonal is the classic "don't steal this" look. Sits at 45 degrees across the whole slide, hard to crop out. Center is good when you want one clean word visible without covering the corners. Bottom right is the subtle option, like a signature. If you're not sure, go diagonal.
Yes. No account, no card, no "free trial" countdown. Your file gets uploaded, processed, and deleted from our server shortly after. The only watermark on your output is the one you typed in.
A visible stamp makes people think twice before ripping your slides.
Type anything. Pick a size from 24 to 72. Done.
From a whisper at 10% to a shout at 90%. 30% is the sweet spot.
Center, diagonal across the slide, or tucked in the bottom right.
