How to watermark photos with your handle

  1. Drop your images or videos. Drag one or many into the studio: photos as PNG, JPEG, WebP, BMP, SVG or GIF, clips as MP4, WebM or MOV.
  2. Type your handle. Add one or several social media handles, pick a font and color, or stamp a logo instead.
  3. Place and download. Choose a corner or drag the watermark anywhere on the preview, then download every file, zipped when there are several.

The result: your handle sits quietly in the corner, at full resolution.

Watermark photos without uploading them anywhere

Handle Adder is a free online watermark tool that runs entirely in your browser. There is no upload, no processing queue and no account: every image and video is watermarked on your own device by the browser itself. Turn off your connection once the page is open and it keeps working. That makes it a fast, private way to batch watermark images and clips before you post them to Instagram, X, TikTok or anywhere else your work travels without you.

Frequently asked questions

How do I add my Instagram handle to my photos?

Drop your images above, type your handle (for example @yourname), pick a corner and download. You can also drag the watermark anywhere on the live preview, and every image keeps its own placement.

Are my images uploaded to a server?

No. Everything happens locally in your browser: your photos, videos, logo and fonts never leave your device. Once the page has loaded, it even keeps working with your connection switched off.

Can I watermark videos too?

Yes. Drop a video next to your images and the same watermark is stamped on every frame, with the sound kept. Your browser re-encodes the clip in real time, so a one-minute video takes about a minute: keep the tab in view while it works. Like everything else, it never leaves your device.

Can I batch watermark multiple photos at once?

Yes. Drop as many images as you like, style the watermark once, and download them all as a single zip. "Place all images like this one" copies one placement to the rest.

Does it work on phones and tablets?

Yes. The studio runs in any modern mobile browser, and you can drag the watermark into place with your finger on the live preview. Your images export at full resolution, with no extra branding stamped on your output.

Can I use my own logo or font?

Yes. Add a logo image (alone or stacked above your handle), choose one of six bundled fonts, or load any .ttf, .otf, .woff or .woff2 font of your own. Like your images, it stays on your device.

Which image and video formats are supported?

Images: PNG, JPEG, WebP, BMP, SVG and GIF (first frame). Output keeps the input format for PNG, JPEG and WebP; other formats export as PNG. Videos: anything your browser can play, such as MP4, WebM and MOV, exported as MP4 (or WebM where the browser cannot encode MP4).
