Watermarks, background changes, blur and hidden messages
Visible watermarks, background replacement by colour, automatic background blur, whole-image blur, and a tool for hiding a short text message inside a PNG.
Watermark Tool
Place a text or logo watermark in a corner, the centre or tiled across a photo, with adjustable size, colour and opacity. Runs in your browser; no upload.
Protect with Watermark
Cover a photo with a repeating diagonal text or logo watermark that is hard to crop out. Useful for proofs and previews. Processed in your browser.
Image Steganography
Hide a short text message inside the pixels of a PNG and read it back later with the same tool. Explains how LSB steganography works and its limits.
Change Background
Remove a photo background automatically or by colour, then make it transparent, fill it with a colour or put a new picture behind the subject. Runs in your browser.
Blur Background
Keep the subject sharp and blur everything behind it, using an open-source segmentation model that runs in your browser. Adjustable blur strength. No upload.
Transparent Background Maker
Turn a solid white or coloured background transparent and save a PNG. Removes only background connected to the image edges, so the subject stays intact.
Background Color Changer
Replace a solid background with any colour you pick, for product photos, ID-style pictures and graphics. Colour-key based, processed in your browser.
Blur Image
Apply an even blur to a whole image, from a slight softening to an unrecognisable wash, for backgrounds, placeholders and privacy. Runs in your browser.
