Every day, thousands of images are copied without permission. Here are 5 practical methods to protect your work as a photographer or creator.

1

Add a visible watermark

The watermark is the first line of defence against image theft. A semi-transparent text or logo overlaid on your photo deters theft and identifies the author, even if the image is shared out of context.

Best practices:

  • Place the watermark in the centre or as a tiled pattern to prevent cropping
  • Use an opacity between 25% and 50% — visible without ruining the image
  • Include your name, website or © symbol

Register your photos legally

A watermark provides visual protection, but does not constitute legal proof. To prove that you are the author in the event of a dispute, register your photos with a timestamped deposit service.

The deposit generates a certificate with a SHA-256 hash, timestamp and verifiable QR code — admissible evidence in the event of a dispute.

Recommended

Copyright01 allows you to register your photos with a timestamped certificate, a SHA-256 hash and a verifiable QR code.

3

Preserve EXIF metadata

The EXIF data in your original files — date taken, camera, GPS coordinates — provide additional evidence of authorship.

Always keep your RAW or unmodified original files in a safe place. This metadata can make the difference in the event of a dispute.

4

Use reverse image search

Tools such as Google Images, TinEye or Copytrack allow you to search where your photos appear online.

Carry out regular checks — at least once a month — to detect unauthorised uses of your work.

5

Publish at reduced resolution

On social media and your portfolio, publish versions at lower resolution (1200-2000 px). This makes unauthorised commercial use difficult, while keeping sufficient quality for web display.

Always keep your high-resolution files locally — they will serve as proof of originality.

The double protection

The most effective strategy combines visual protection and legal protection.
