Questions

Are my photos uploaded to a server?
No. The tool decodes, watermarks and zips your images inside the browser tab. The only network requests are for the page itself and, if you buy Pro, the license check.
What is free and what needs Pro?
Free covers up to 10 photos per batch with text or logo watermarks, corner placement, JPEG/PNG/WebP output and quality control. Pro removes the batch limit and adds tiled watermarks, resizing, filename patterns and priority support. It is a one-time $39, not a subscription.
Which file types are supported?
JPEG, PNG, WebP, GIF (first frame), BMP and AVIF on modern browsers. iPhone HEIC files need to be converted to JPEG first, or exported through Safari on iOS 17+.
Will the watermark cover the product?
Pick a corner, keep the size around 4–8% of the image's short side and lower the opacity. The preview shows the exact result before you export.
Do you keep my license key?
The key is stored in this browser's local storage so Pro stays active. It is sent to our server only to activate and validate it with Creem, our payment provider.
Can I use the watermarked photos commercially?
Yes. You own the photos and the watermark; the tool only produces the files. You are responsible for having the rights to any logo you upload.
