Watermark Your Photos — Free, Private, In Your Browser

Guide: adding a clear watermark to your own photos

Every setting the tool offers

In the Text tab you type a single line of up to 120 characters. The box starts with the sample text "© Image EditPro", so replace it with your own name or brand. Font size runs from 12 to 200 pixels, and there is a colour picker (white by default), a choice of sans-serif, serif or monospace, and switches for bold (on), italic and a soft dark shadow (on). The fonts come from your device, so the exact look can vary slightly between computers and phones.

In the Logo tab you choose a PNG, JPG or WEBP logo and set its width from 5 to 50 percent of the photo's width, with 20 percent as the start. Both modes share a nine-position grid (bottom-right by default), a margin from the edges of 2 percent of the image width, and an opacity slider from 0 to 100, starting at 50. The preview is scaled to 800 pixels, but the final image is drawn at full resolution and saved in your original format, with JPG and WEBP at quality 0.92. Nothing is uploaded.

The tool places one watermark per image. It does not tile a repeated pattern across the photo, and it processes one photo at a time.

Sizing the watermark for different photos

Font size is measured in pixels of the full image. The same 48-pixel text that looks right on a 1080-pixel Instagram image is tiny on a 4000-pixel phone photo, so judge the size in the preview rather than by the number. Logo size is a percentage of the image width, which keeps it consistent across photos of different sizes; if you watermark many photos with different dimensions, the Logo tab gives more even results.

Keeping it readable on any background

White text with the shadow switched on stands out on most photos. On bright skies, white walls or white product backgrounds, choose a dark colour instead. Opacity between about 30 and 60 usually keeps the mark visible without hiding the picture. For logos, use a PNG with a transparent background; a JPG logo brings its own white or coloured box with it.

Who uses watermarks, and how

• Instagram and WhatsApp sellers marking product photos with the shop name. Check marketplace rules first: many marketplaces do not allow watermarks on main listing images.
• Photographers sending proofs to clients, often with a centred mark at low opacity.
• Teachers and coaching centres marking notes and question images shared in groups.
• Anyone sending a copy of an Aadhaar, PAN or other ID to a bank or landlord: writing the purpose and date across it, such as "For KYC at XYZ Bank only", makes the copy harder to misuse.

What a watermark does and does not protect

A watermark shows where an image came from and discourages casual reuse. A small mark in a corner is easy to crop off; a centred mark is harder to remove but more distracting. It is not legal protection on its own. Use this tool only on images you own or have permission to mark.

Before you download

• Replace the sample text and check the spelling.
• Look at the preview at the size people will actually see the image.
• Keep an unmarked original, since the watermark is part of the pixels and cannot be removed later.
• Compress the result for web or chat with Compress to Size if needed.
