Are my images uploaded anywhere?

No. Every tool runs inside your browser using Web Workers and WebAssembly. Files never leave your device, and there is no server, account or tracking.

Can I use my own logo?

Yes. Choose “Logo” and pick a PNG; transparency is preserved. Set its width as a percentage of the photo.

Will the watermark be the same size on portrait and landscape photos?

Yes. Size and position are stored relative to each image, so the batch looks consistent.
