Yes. Upload your logo in PNG format with a transparent background for best results. The logo is overlaid on your product images with your chosen opacity, position and size.
Amazon prohibits watermarks or logos on main product images. Additional product images may include watermarks. Watermark only your store images and keep clean versions for marketplace submissions.
The lower corners (bottom-right or bottom-left) are the industry standard for product watermarks. They are visible enough to deter theft without obscuring the main product.
40–60% opacity produces the most professional results. The watermark is clearly visible at this level without dominating the image.

Image theft is a significant and growing problem in e-commerce. Competitors and third-party sellers regularly steal product photography from established stores, using your investment in professional images without permission or attribution.
A visible watermark is the most cost-effective deterrent against image theft. It makes your images significantly less useful to thieves while simultaneously reinforcing your brand identity every time your product photo appears — on your store, in Google Shopping, on social media, or anywhere else.
The bottom corners are the industry standard for product watermarks. They're visible enough to deter theft but don't obstruct the main product. Avoid centre placement — it obscures the product and significantly hurts conversion rates.
A semi-transparent watermark is more professional than a fully opaque one. At 40–60% opacity, the watermark is clearly visible and deters theft without dominating the image. High opacity (80%+) looks aggressive and can reduce customer trust.
The watermark should be noticeable but not dominating. For a 1000px image, a logo of 150–250px width is typically ideal. imgflow sets size as a percentage so it scales correctly across all image sizes in your batch.
Use your logo watermark for professional product photography where brand recognition matters. Use text watermarks for catalogue images, supplier photos, and cases where you want to include your website URL or copyright notice.
