A watermark can identify the owner or source of an image. It can include a logo, brand name or other visible mark.
A useful watermark should be noticeable without making the main image difficult to view.
Choose the position
Corners are common locations, but the best position depends on the composition and how easily the image may be cropped.
Adjust opacity
A slightly transparent watermark can remain visible while distracting less from the image.
Use an appropriate size
The mark should scale with the image rather than being excessively large or too small to read.
Use a clean logo file
A high-quality transparent logo generally produces a cleaner result.
Decide what the watermark is meant to do
A watermark can identify a photographer, show a company name or make casual reuse of an image more difficult. The purpose should influence how prominent it is.
A portfolio photograph may need a subtle brand mark, while a preview image may require a more visible watermark.
Choose position carefully
Corner placement keeps the main subject clear but can sometimes be removed easily by cropping. A mark closer to the subject may be harder to remove but can also distract from the image.
Balance protection with the quality of the viewing experience.
Use opacity and contrast together
A watermark that is too transparent can disappear over some parts of an image, while a fully opaque mark may dominate the design.
Test it over both bright and dark areas and adjust opacity or color so it remains visible without becoming the main subject.
Use a suitable logo source
If the watermark is a logo, use a clean high-resolution version, ideally with transparency when appropriate.
Avoid taking a very small logo and enlarging it dramatically because blurred or pixelated branding can make the finished image look less professional.
Test before applying to many images
Before processing a large collection, try the watermark on several images with different backgrounds. Confirm that its size, position and visibility work consistently.
Keep unwatermarked originals so you can later create another version with different branding if necessary.
Keep watermark placement consistent
When publishing a group of images, use a consistent watermark size and position whenever the compositions allow it. Consistency makes the branding look intentional rather than randomly added.
If one image has a very bright or dark background, adjust contrast or position slightly so the watermark remains readable, but avoid changing its appearance so much that every image looks unrelated.
Export a clean copy for publishing
After adding the watermark, review the final image at normal viewing size and make sure the mark remains readable without covering important details.
Keep the unwatermarked source separately. The watermarked image should usually be treated as a publishing copy rather than the only version of the original image.

Choose settings based on where the file will actually be used rather than simply aiming for the smallest size or the highest possible dimensions. Keep your original file, review the processed result and choose a format that suits your final destination.
