Add a Watermark to Your Photo

Put your name or copyright line on an image before you publish it. The mark is drawn at full resolution in your browser, and your original file is untouched.

How it works

  1. 1

    Load a photo

    JPG, PNG or WebP, read directly in your browser.

  2. 2

    Set the mark

    Text, position, size, opacity and tiling, previewed live.

  3. 3

    Download

    The mark is drawn at full resolution and saved as a PNG.

What a visible watermark is actually for

A visible watermark is a deterrent and an attribution, not a lock. It makes casual reuse awkward, it travels with the image when someone saves and reposts it, and it tells anyone who sees the picture where it came from. Those are real benefits and they are the honest ones.

What it does not do is prevent theft. Anyone determined can crop a corner mark, clone it out, or find an unmarked copy elsewhere. Design your mark around deterrence and credit rather than around the belief that it makes an image safe to publish.

Choosing a placement that survives cropping

The trade-off in watermarking is always the same: the harder a mark is to remove, the more it intrudes on the picture.

  • A corner mark is the least intrusive and the easiest to crop away — fine for attribution, weak as a deterrent.
  • A centre mark is hard to remove and hard to ignore. Appropriate for proofs and previews, not for a portfolio piece.
  • A tiled mark covers the whole frame and survives any crop, at the cost of dominating the image. This is the standard choice for client proofs and stock previews.
  • Low opacity looks more professional and is easier to remove; higher opacity is the opposite. Around 40–50% is a reasonable middle.

How this differs from metadata removal

Everything else on this site edits the file's container and leaves the picture untouched. Watermarking is the opposite: it draws into the pixels, so the image genuinely changes and the output has to be re-encoded.

The tool saves as PNG, which is lossless, so the watermarked copy does not accumulate JPEG compression artefacts on top of your original's. The file will usually be larger than the JPEG you started from — that is the cost of not re-compressing.

A practical order of operations: clean the metadata first, watermark second, publish third. Watermarking re-encodes and can add its own metadata from the browser's encoder, so cleaning last is also defensible; the important thing is checking the final file rather than assuming.

Watermarking is not a substitute for the other steps

A watermarked photo still carries its EXIF, including GPS coordinates, unless you remove it. The mark on the picture and the metadata inside the file are entirely separate — protecting one does nothing for the other.

What this tool does

  • Drawn at the image's real resolution, not at preview size
  • Live preview of position, size, opacity and tiling
  • Nothing is uploaded, and your original file is not modified

What it does not do

  • The output is re-encoded as PNG — this is a pixel edit, unlike metadata removal
  • Text marks only in this version; image and logo marks are not supported yet
  • A visible mark deters casual reuse; it cannot prevent a determined copier

Frequently asked questions

Does watermarking upload my photo?

No. The image is decoded into a canvas in your browser, the mark is drawn there, and the download is produced locally.

Will the watermark reduce my image quality?

The mark is drawn into the pixels, so the picture does change where the text sits. The output is saved as lossless PNG, so no additional compression artefacts are introduced elsewhere.

What opacity should I use?

Around 40–50% for a balance of visibility and subtlety. Go higher for client proofs where deterrence matters more than appearance.

Can I add a logo instead of text?

Not yet — this version supports text marks only.

Does a watermark remove my photo's location data?

No. Those are separate: the watermark is in the picture, the GPS coordinates are in the file's metadata. Use the metadata remover for the second one.

Can I save the watermarked file as a JPEG?

Not in this version — the output is PNG, which avoids adding compression artefacts on top of your original.

Will the watermark look the same on a large print?

It scales with the image, since the size is set as a percentage of the shorter side rather than in fixed pixels.

Can I remove the watermark later?

Not from the exported file. Keep your original — the tool never modifies it.

Can I watermark several photos at once?

Not yet — one image at a time here. Batch processing exists for metadata removal, but watermarking still needs each image positioned individually.
