What is a photo watermark tool?

A watermark is a visible mark, usually your name, website or logo, placed on top of an image. It tells viewers who made the photo, discourages people from passing it off as their own and keeps your brand attached when images are shared.

This tool applies the same watermark to a whole batch of photos with one click. You design it once on a live preview, using text, a logo or both, then every image is processed at full resolution. The mark scales with each photo's width, so it looks the same on a portrait phone shot as on a wide landscape.

How to add a watermark to photos in 5 steps

  1. Add photos

    Drop up to 50 JPG, PNG or WebP images. Tap a thumbnail to preview it.

  2. Write your text

    Enter your name or URL, then choose font, colour, size, opacity and rotation.

  3. Add a logo (optional)

    Tick Logo watermark, pick a PNG or SVG and set its size and opacity.

  4. Place it

    Choose one of nine positions or Tile to repeat the mark across the whole image.

  5. Export

    Click Watermark images, then save single files or download all as a ZIP.

Saved as lossless PNG with transparency.

Logo: PNG, SVG, JPG, WebP, GIFlogo input

Transparent PNG or SVG looks best.

Up to 50 images per batch. Photos larger than 16.7 megapixels are scaled down to the browser canvas limit. GIF, BMP and AVIF photos are accepted and saved as PNG.

How does it work?

Each photo is decoded by your browser and drawn to a canvas at full size. The watermark is then painted on top using Canvas text and image drawing, and the result is encoded back to its original format. The ZIP is built locally too.

📏

Relative sizing

Text size and logo width are a percentage of each photo's width, so batches look consistent.

🔁

Tiling

A repeating diagonal pattern with adjustable spacing covers the whole image.

🌓

Soft shadow

An optional shadow keeps white text readable on light areas.

🔒

Private

Photos never leave your device, and re-encoding strips EXIF metadata such as GPS.

Watermark best practices

A good watermark protects your work without ruining it. The balance depends on why you are watermarking.

For portfolios and social media

  • Keep it small and quiet: your name or handle at 3–5% of the width, 40–60% opacity.
  • Place it in a corner but away from the very edge, so a simple crop doesn't remove it. The edge-margin slider helps.
  • Use a clean sans-serif or your own logo, and the same position on every image for a consistent look.

For client proofs and stock previews

  • Use Tile mode with a rotation of around −30°, so the mark crosses the subject and is hard to clone out.
  • Lower opacity to 20–35% so clients can still judge the photo.
  • Deliver the clean full-resolution files only after payment.

No visible watermark is impossible to remove, but a well-placed one makes misuse much more effort than it is worth.

Text or logo: which watermark should you use?

Text watermarks are quick and flexible. A copyright line such as "© Jane Doe 2025" or your website address tells people exactly where the photo came from. Short text works best; long sentences compete with the photo.

Logo watermarks look more polished and are easier to recognise at a glance. Use a PNG or SVG with a transparent background; a logo on a white box covers part of the image. If yours only exists on white, clear it first with the transparent background tool.

You can also combine them, for example a logo bottom-right and a faint tiled URL behind it.

Colour and contrast

White text with a soft shadow reads on most photos. For bright snowy or beach scenes, try dark grey text at moderate opacity instead.

Preparing watermarked images for the web

Watermarking is usually the last step before publishing, so it pays to finish the other edits first.

  • Crop and resize first. Apply your crop or social-media size before watermarking, otherwise a later crop may cut the mark off. The image resizer handles batches.
  • Compress afterwards. Large camera JPGs stay large. Run the watermarked set through the image compressor for faster pages.
  • Keep originals. The tool never changes your source files, so store the unmarked versions safely for clients and prints.
  • Mind the metadata. Watermarked files are saved without EXIF, which removes camera details and location. If you need copyright metadata, add it afterwards in your photo software.

Each file keeps its original name with "-watermarked" added, so the batch sorts neatly beside your originals.

Frequently asked questions

Drop up to 50 photos into the tool, design your text or logo watermark on the live preview, and click Watermark images. Every photo is processed with the same settings. Then download the files individually or all together as a single ZIP archive.
Yes. Tick Logo watermark and choose a PNG, SVG, JPG, WebP or GIF file. Set its size as a percentage of the photo width, its opacity and its position. A transparent PNG or SVG logo gives the cleanest result on photos.
For everyday sharing, a lower corner with a small margin from the edge works well and stays out of the way. To make removal harder, place the watermark over part of the subject or use a tiled pattern across the whole image.
Most photographers use 40–60% for a corner signature, which is visible without being distracting. For proofs and previews that must be hard to reuse, a tiled watermark at 20–35% opacity covers the whole image while still letting viewers judge composition and colour.
Photos are processed at their original resolution. PNG output is lossless, while JPG and WebP are re-encoded at 92% quality, which is visually very close to the original. Only images above 16.7 megapixels are scaled down to fit browser limits.
No. All watermarking happens inside your browser on your own device using the Canvas API. Photos are never uploaded or stored, which makes the tool suitable for client work, unreleased products and private family pictures. It keeps working even if your connection drops after the page loads.
Yes. Choose Tile in the position grid to repeat the text or logo across the entire photo. Use the rotation slider for a diagonal pattern and the spacing slider to control how dense the repetition is. Lower opacity keeps the photo visible.
It scales relative to each photo's width. Text size and logo size are set as a percentage, so a 5% watermark looks proportionally identical on a small phone photo and a large camera image within the same batch, whatever their orientation.
Determined editors can remove small corner marks with retouching tools. Placing the watermark over important detail, using tiling and keeping full-resolution originals private makes removal much harder. A watermark deters casual copying and keeps your name attached, rather than guaranteeing complete protection.
You can watermark JPG, PNG and WebP photos, and each keeps its format on export. GIF, BMP and AVIF images are also accepted where your browser can open them and are saved as PNG. Logos can be PNG, SVG, JPG, WebP or GIF.
