Why add a watermark to your images?
A watermark is a semi-transparent text or logo laid over an image to identify its owner and discourage unauthorized use. Photographers, illustrators, and small businesses use watermarks to protect work they share online, so that even if a picture is copied or reposted, the credit travels with it. A subtle watermark in the corner keeps your brand visible without ruining the composition, while a larger, lower-opacity mark across the center makes an image much harder to reuse without permission.
Watermarks are also a lightweight branding tool. Adding a consistent logo to product photos, social media graphics, or marketing images reinforces recognition every time the picture is viewed or shared. Because the mark is baked directly into the pixels, it stays attached to the file wherever it travels, unlike metadata that can be stripped in a click.
Pixohub lets you place either a custom line of text or your own uploaded logo onto any image. You control exactly where it sits, how big it is, and how transparent it appears, so you can strike the right balance between protection and a clean look. Everything renders live, so you can experiment freely before saving.
How Pixohub protects your privacy
Unlike most online watermarking services, Pixohub does all of its work inside your browser using the HTML Canvas API. Your original image and your logo are decoded and composited locally on your own device, and the finished file is generated in memory. Nothing is ever uploaded to a server, which means your photos stay completely private and the tool works even on a slow or intermittent connection.
This local-first approach has practical benefits beyond privacy. There are no upload waits, no file size caps imposed by a server, and no daily quota — you can watermark as many images as you like, back to back. And because Pixohub is genuinely free, we never stamp our own logo onto your output. The only watermark on the finished image is the one you added yourself.
Choose a low opacity, around 30 to 50 percent, if you want the watermark to be present but unobtrusive, or a higher opacity for stronger protection. Positioning the mark over important detail in the photo, rather than in an empty corner, makes it far more difficult for someone to crop or clone it out.
