Quick answer
To watermark photos, drop them into the box, choose “Text” and type your mark (for example “© Your Studio”) or choose “Logo” and upload your logo, adjust the position, opacity and angle, then download each image or a ZIP. Images are processed in your browser and never uploaded; up to 30 images at a time.
What is an image watermark?
A watermark is a faint line of text or a logo printed on a photo to credit the author or shop, or to discourage people from reusing the image without permission. This tool applies the same watermark to every image in one go, so a whole set of product shots or event photos comes out consistently marked.
How to watermark images
- 1
Click “Choose files”, drag and drop, or paste (Ctrl + V) JPG, PNG or WebP images. The first image is used for the preview.
- 2
Choose “Text” and set the wording, font, size (as a percentage of image width), colour, bold and outline; or choose “Logo”, upload your logo and set its width.
- 3
Adjust “Opacity” and “Rotation”. Under “Layout”, pick “One position” and click one of the nine spots, or “Tile across” to repeat the mark over the whole image.
- 4
Pick an output format (Keep format, JPG, PNG, WebP), check the results, then download images one by one or all of them as a ZIP. If you change a setting after the results are ready, click “Apply new settings” to redo the batch.
Which watermark for which job
| Goal | Suggested settings | Why |
|---|---|---|
| Credit on your photography | Small text at 3–4%, bottom right, 50–70% opacity | Stays out of the subject's way but survives reposting |
| Product photos for an online shop | Logo at 15–25%, bottom or centre, 30–50% opacity | Brand is recognisable, and it is harder to crop when it sits near the product |
| Proofs sent before payment | “PROOF” text, tiled, −30° rotation, 20–30% opacity | Covers the whole frame, so it cannot be cropped or cleaned up quickly |
| ID scans attached to an application | “For X application only”, tiled, 25–35% opacity | Makes it harder to reuse the ID image for something else |
These are comfortable starting points; check the preview on your actual photos and tune for their colours.
Output formats
| Format | Good for | Note |
|---|---|---|
| Keep format | Getting the same type out as in | JPG stays JPG, PNG stays PNG |
| JPG | Photos, social media, messaging | Small files; no transparency |
| PNG | Graphics, text-heavy images, transparency | No quality loss but larger files |
| WebP | Images for websites | Smaller than JPG at similar quality; some older browsers can't export it |
Real-world examples
A clothing shop posting 20 product shots
Choose “Logo”, upload a transparent PNG logo, width 20%, bottom centre, 40% opacity. All 20 images get the logo in the same place and download as one ZIP.
A photographer sending proofs
Choose “Text”, type “PROOF · Studio An”, select “Tile across”, rotation −30°, opacity 25%. The client can judge the composition but can't use the image until they get the originals.
Sending an ID card photo to a bank
Type “For opening an account at Bank X only, 21 Oct 2026”, tiled, 30% opacity. If the image ever leaks, the wording makes its intended use obvious.
Common problems
- The text is hard to read on a busy background.
- Turn on “Outline” to give the letters a contrasting edge, raise the opacity, or switch to bold.
- A corner watermark is easy to crop out.
- Place it near the subject (centre) or use “Tile across”. No watermark is impossible to remove, but covering more of the image makes removal far more work.
- The logo has a white box around it.
- The logo is a JPG, which has no transparency. Use a transparent PNG or SVG version of the logo.
- The output is larger than the original.
- Images are re-encoded after the watermark is drawn. Choose JPG or WebP and lower “Quality” to around 80–85%.
- A portrait phone photo comes out sideways.
- The tool applies the EXIF orientation when it opens the image, so results should be upright. If not, rotate it first with the “Rotate & Flip Image” tool.
Sizes scale with the image width
Text size, logo width and edge margin are all percentages of each image's width. In a batch that mixes 1,000 px and 6,000 px images, the watermark takes up the same share of every image, and the preview matches what you download.
The output is a freshly encoded image, so it does not carry the original's EXIF data (camera, GPS location). If you only want to remove EXIF without drawing anything, use the “EXIF viewer and remover” tool.
Does a watermark protect copyright?
A watermark is not what gives you copyright: in most countries, including under the Berne Convention, copyright exists as soon as the work is created. A watermark tells viewers who made the image, makes unauthorised reuse more awkward, and is useful evidence if you need to file a complaint.
Glossary
- Watermark
- Text or a graphic overlaid faintly on an image to show its source, author or intended use.
- Opacity
- How solid the watermark is: 100% is fully opaque, lower values let the photo show through.
- Tile
- Repeating the watermark in staggered rows over the entire image instead of placing it once.
- Transparency
- Image areas with no colour (common in PNG, SVG and WebP), which let a logo sit on a photo without a white box.
Frequently asked questions
Are my images uploaded?
No. Images and logos are read and drawn in your browser, so it is safe for private photos and documents.
Can I watermark many images at once?
Yes, up to 30 images per batch, 25 MB each. All of them use the same settings and can be downloaded together as a ZIP.
Does it support accented text and symbols?
Yes. Text is drawn with your system fonts, so accents and symbols such as “©” and “®” display correctly.
Does a PNG logo keep its transparency?
Yes. Transparent areas of the logo stay transparent on the photo. SVG logos work too.
Can a watermark be removed afterwards?
Not from the output: it is drawn into the pixels. Keep your originals if you may need unmarked copies later.
Does it work on a phone?
Yes. Pick photos from your gallery, adjust the settings and download; very large images may be slower on older phones.
