Image Watermark

Add a text or logo watermark to one image or many.

Free tools that run in your browser. Nothing you type, open or create is uploaded to NerdBible or anyone else.

The same watermark is placed on every image at the same relative size and position, so it looks alike on large and small photos. Saving is done at full resolution. A watermark discourages casual copying, but it can be cropped or edited out; a repeated, semi transparent one across the whole image is the hardest to remove.

How to use it

  1. Choose or drop one or more images.
  2. Type your watermark text, or switch to Logo image and choose a logo file.
  3. Set the size, opacity and rotation, then pick a corner or the centre, or tick Repeat across the image.
  4. Check the preview, then download each image or all of them in one ZIP file.

Questions

Are my photos uploaded?

No. The watermark is drawn by your browser on your device, and the files are saved straight from there.

Is the photo quality reduced?

Images are saved at their full size. JPG and WebP are saved at high quality (92), which is visually the same for photos; choose PNG if you need no compression at all.

Is the location and camera data kept?

No. The new copy is redrawn from the pixels, so EXIF data such as GPS position is not carried over.

What logo file works best?

A PNG or SVG with a transparent background, so only the logo itself shows. A JPG logo will show its rectangular background.

About this tool

About the image watermark tool

A watermark puts your name, website or logo on a picture so it stays credited when it is shared, copied or reposted. This tool adds one to a single image or to a whole set in one go, which saves repeating the same steps in a photo editor.

How to use it

  • Add your images. Several can be processed together with the same settings.
  • Choose a text watermark, such as your name or a copyright line, or a logo image. A PNG logo with a transparent background looks cleanest.
  • Set the position, size and opacity, and check the preview.
  • Download each marked image, or all of them together.

Tips for a watermark that works

A small, faint mark in a corner credits the photo without spoiling it, but it is also the easiest to crop off. For proofs you send to a client before payment, a larger mark across the middle is harder to remove. Size the watermark relative to the image rather than in fixed pixels so it looks the same on large and small pictures, and keep a clean original of every photo somewhere safe.

No watermark is impossible to remove, so treat it as a deterrent and a credit line rather than protection.

Images are marked on your device and are never uploaded.
