What Is Image Watermarking?

A watermark is a text or logo overlay stamped onto an image — usually semi- transparent — to mark ownership or discourage unauthorized reuse. It's common for photographers sharing previews, businesses branding product photos, and anyone posting images publicly who wants their name attached to the work. The overlay is drawn directly onto the image's pixels using the Canvas API, at whatever opacity, size, and position you choose, so the result is a single flattened image file ready to share or publish.

How to Use This Tool

1Add your photosOne or many at once, including iPhone HEIC photos.
2Type your name or upload a logoPick a font, bold or italic and a colour. A soft shadow or outline keeps it readable on both light and dark photos. Your logo is remembered for next time.
3Place itDrag on the photo or tap a corner. Choose "Repeat across photo" for a diagonal pattern that is hard to crop out.
4DownloadSave one photo, or every photo in a single ZIP, at full size and quality.

When Watermarking Is Worth Doing

Sharing photo previews or proofs publicly before a client has paid for full-resolution, unwatermarked files.
Posting original photography, artwork, or designs on social media where reposting without credit is common.
Branding product or portfolio images consistently with a small logo so shared images are recognizably yours wherever they end up.
Marking draft or internal documents as not-final before wider circulation.

Good to Know

For sharing on social media, 50–70% opacity in a corner looks professional. For client proofs, use "Repeat across photo" at 25–40% opacity so it can't be cropped away.
The watermark size is based on the shorter side of each photo, so portrait and landscape photos in the same batch get the same-looking mark.
White text with a soft shadow works on almost any photo. Turn on the background for very busy photos.
For a logo, a PNG with a transparent background looks far better than a JPG with a white box.
Your style settings and logo are saved in this browser, so next time you only need to add photos and download. Nothing is uploaded.

Frequently Asked Questions

Can I use my own logo as a watermark?

Yes — switch to "Logo / Image Watermark" mode and upload any image file. A PNG with a transparent background gives the cleanest result.

Does the watermark permanently protect my image from copying?

A watermark discourages casual reuse and marks the image as yours, but a determined person can still crop or edit it out — it's a deterrent, not an unbreakable protection. For images where reuse would be a serious problem, use "Repeat across photo", which covers the whole image and is much harder to remove than a corner mark, and keep your unwatermarked originals private.

Can I remove the watermark later?

No — the watermark is drawn directly into the downloaded image's pixels, so keep your original, un-watermarked file if you might need it later.

What opacity should I actually use?

Somewhere around 40–60% is the common sweet spot — visible enough to read clearly, transparent enough not to obscure the photo underneath. Go higher only if deterring reuse matters more than the watermark looking subtle.

Can I watermark several photos with the same text or logo in one go?

Yes. Add as many photos as you like and the same watermark is applied to all of them, sized to each photo. Check any photo in the preview, then download them all as one ZIP.

Is my image uploaded to a server?

No. Watermarking happens entirely in your browser, so your photos never leave your device.
