How to add a watermark to photos, one or 100 at a time
Published
Open Watermark photosOpen Watermark photos, drop in your photos, type your text (it starts as "© Your name") or switch to Logo, choose a position, size and opacity, and press Download all. Every photo gets the same watermark, scaled to that photo, and comes back in its own format.
Steps
- Open Watermark photos and drop in up to 100 JPG, PNG or WebP photos.
- Under Watermark, choose Text and type your line, or Logo and choose your logo file.
- For text, pick a Colour: White, Black, Yellow, Red or your own.
- Under Position, tap one of the nine spots, or Tile across the whole photo.
- Choose a Size (Small, Medium, Large), set Opacity between Faint and Solid, and pick an Angle: Straight or Diagonal.
- Flip through the photos in the batch to check the mark sits well on each one.
- Press Download for the photo on screen, or Download all for one zip.
Choosing where the watermark goes
The setting depends on why you are adding it:
| Goal | Position | Size | Opacity |
|---|---|---|---|
| Credit on photos you post | Bottom right | Small | 50-60% |
| Brand mark on product photos | Bottom right or left | Medium | 60-80% |
| Preview copies you send to a client | Tile, Diagonal | Medium | 25-40% |
| ID or document copies for one purpose | Tile, Diagonal | Large | 30-50% |
The tool starts at bottom right, Medium, 60% opacity, straight, which suits a credit line on most photos.
Size is relative to each photo
Small, Medium and Large set the watermark's width as a share of the photo's width: 15%, 25% and 40%. That is why one setting works across a mixed batch: a 4000 pixel photo and a 1080 pixel photo get a mark that looks the same size relative to the picture.
Corner or tiled
A mark in a corner is easy to read and stays out of the way, but it is also easy to crop off. Tile across the whole photo repeats the mark over the entire picture, which is much harder to remove and makes sense for previews of work you have not been paid for yet, or copies of documents. Pair it with Diagonal and a low opacity so the photo is still clear.
For a copy of an ID card or passport that you send somewhere, a tiled line naming who it is for and the date, such as "For XYZ bank, 12 Nov 2026 only", makes the copy less useful to anyone else who gets hold of it.
Getting a logo to look clean
- Use a PNG with a transparent background. A logo on a white box shows the box on every photo.
- A single-colour version of your logo (all white or all black) reads better on busy photos than a full-colour one.
- If the logo disappears on light photos, add a second batch with a darker version for those.
Quality and format
The photo keeps its full resolution. PNG files stay lossless and keep any transparency; JPG and WebP files are saved again at 92% quality, which looks the same at normal viewing size. If you need the files smaller afterwards, for a website or email, run them through Compress image or Resize image.
Questions
Can I watermark more than 100 photos?
Yes, in more than one batch. If you add more than 100, the first 100 are kept and the tool tells you to do the rest in another batch.
Are my photos uploaded to add the watermark?
No. The watermark is drawn in your browser, and your photos stay on your device.
Does the tool add its own watermark?
No. The only mark on the photos is the one you set.
Can this remove a watermark?
No. It only adds watermarks.
Do phone photos come out sideways?
No. Phone photos keep the right way up.
