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.

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

  • A semi-transparent watermark (40–70% opacity) protects your work without overwhelming the image underneath.
  • For a logo watermark, a PNG with a transparent background blends in far better than a JPG with a white box around it.
  • Corner positions (bottom-right is the most common) keep the watermark visible without covering the main subject.
  • A watermark placed dead center is much harder to crop out than one in a corner, if deterring reuse matters more to you than a clean, unobtrusive look.
  • Nothing is uploaded — the watermark is drawn directly onto the image in your browser using the Canvas API.

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, watermark placement matters (center is harder to remove than a corner) and keeping your unwatermarked original private matters even more.

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?

This tool applies a watermark to one image at a time so you can position it precisely on each. For applying the exact same watermark across a whole batch automatically, that's on the roadmap alongside the other bulk tools.

Is my image uploaded to a server?

No. The entire watermarking process runs locally in your browser.
