When to use this

Use this before you share a photo you want credited: a proof for a client, a listing, or a picture that should carry your name. The pixels stay the same size. The words sit on top.

A corner mark stays out of the middle of the picture. Repeat tiles the same words across the photo, which is harder to crop away. White reads on dark photos. Black reads on light ones. A shadow sits behind the letters so they still show when the photo is mixed.

Strength is how solid the letters are. A lower number sits back. A higher number is easier to read. Size follows the short edge of the photo, so a small picture and a large one get a similar mark.

This stamps the whole batch with the same words. It does not draw a logo, and it does not place the words on one object only. If you need to paint or set type by hand, that is a different job. If you only need a frame, use a border.

JPG cannot store a clear background. If the source has empty pixels, a JPG fills them with white when you save. Keep PNG when you still need those pixels clear. WebP can keep them too.

How to do it

  1. Drop one image or a batch. Files stay on this device.
  2. Type the words. Pick a corner, the centre, or repeat. Set the size, the strength, and white or black.
  3. When you download, pick JPG, PNG, or WebP, and set the quality if you are not saving PNG.
  4. Apply, then download each file or a zip of the batch.

Tips

  • A name in the bottom right is enough for a proof. Repeat is better when you do not want the mark cropped off.
  • White with a lower strength sits quietly on a dark photo. Black does the same on a light one.
  • JPG fills clear pixels with white. Use PNG if you still need transparency.
  • Quality around 0.92 is a good balance for JPG and WebP.

FAQ

Do my photos leave this device?
No. The mark is drawn in this browser. We never receive the files.
Will this change the size of the photo?
No. Width and height stay the same. The words sit on the picture.
Does the site add its own watermark?
No. The only words on the photo are the ones you type.
Can I stamp several images at once?
Yes. They share the same words and settings. Pick the file type when you download, then save a zip.
Can I place the words on one object only?
No. A corner or the centre uses one spot. Repeat covers the picture. Crop first if you only want part of the photo.
Why does my PNG look like a white box as a JPG?
JPG has no transparency. Empty pixels become white. Save PNG if you need them clear.
