Frequently asked questions
Are my photos uploaded anywhere?
No. Every photo is watermarked inside your browser with the Canvas API. Nothing is sent to a server — you can disconnect from the internet after the page loads and keep working.
What is the best watermark to stop photo theft?
A visible mark deters casual theft: sellers commonly use a small logo in a corner at 30–50% opacity, or a diagonal repeating text across the image for stronger protection. Keep it off the product itself so it does not hurt sales.
Which formats are supported?
You can upload PNG, JPEG, WebP, GIF and BMP images. Output is JPEG (smaller files, best for listings) or PNG (lossless).
Is there a batch limit?
The free version processes up to 20 images per batch and downloads them individually or as one ZIP. Batch Watermark Pro ($29 one-time) removes the limit and adds presets, custom fonts and batch renaming.
