Add Watermark to Image Online Free — Text or Logo | AiSmartKit

Once a picture is online, it can be saved and reposted in seconds, often without any credit. A watermark is the simplest way to keep your name attached to your work. Photographers use it to protect their portfolios, online sellers use it to stop others lifting their product shots, and creators use it so every repost still points back to them. This tool lets you add a clean, professional watermark in a minute, with no software to install.

Everything is done inside your browser. Your photos and your logo are never uploaded to a server, and the finished images carry only your own mark.

Text Watermarks

Type anything you like: your name, a copyright line such as "© 2026 Your Studio", your website address or your social media handle. Choose from five font styles, pick a colour or use your exact brand colour, and keep the soft shadow on so the text stays readable over both light and dark parts of the picture. The watermark keeps the same proportions on every image, whether it is a small phone snap or a large camera file.

Logo Watermarks

If you have a logo, switch the type to Logo and upload it. A PNG with a transparent background blends in best, because only the logo itself appears on your photo instead of a white box. Lower the opacity for a subtle, classy mark, or leave it strong for maximum brand visibility. Your logo stays on your device and is never saved anywhere.

Logo and Text Together

Choose Logo + Text to combine both into a single watermark, just like a brand signature. Put your name or web address beside the logo for a neat, wide mark, or under it for a compact stamp that fits nicely in a corner. Kept together, the logo and text share one size and move as a single mark. If you would rather spread them out — say your logo in the top corner and your website along the bottom — choose Separate Places, then drag each one exactly where you want it and give each its own size.

Corner, Custom Spot or Tiled

The Position grid snaps your watermark to any corner, edge or the centre, and the Edge Margin slider controls how far it sits from the border. For an exact spot, simply drag the watermark on the preview. When protection matters most, choose Tile Across Image: your mark repeats over the whole picture, which makes it very hard to crop out or paint over. Tiled watermarks at a low opacity are popular for proof photos, stock previews and digital product mock-ups.

Watermark a Whole Batch

Add up to ten images, set Apply To to All Images, and design your watermark once. It is placed in the same relative spot on every photo, even when they have different sizes and shapes. You can still select any single image and adjust it on its own. Download All as ZIP saves the full set in one go.

Tips for a Good Watermark

• Keep it readable but not distracting: 50–70% opacity works for most corner watermarks.
• For previews you want to protect, use a tiled mark at 25–40% opacity and a slight angle.
• Place corner watermarks over a busy part of the picture so they are harder to remove.
• Use the same text, font and colour on all your images so people start to recognise your brand.

Before watermarking, you might want to crop your photo or resize it for social media. Afterwards, compress the file so it loads quickly on your website, or blur any private details you would rather not share.
