Questions
Is it really free?
Yes — completely free, no registration, and no watermark from us on your images. You only get your own logo.
Are my images uploaded to a server?
No. Every image is processed locally in your browser — nothing is uploaded anywhere, so your photos never leave your device.
Which formats are supported?
PNG, JPG and JPEG. For the logo, a PNG with a transparent background gives the cleanest result.
Can I watermark many images at once?
Yes — batch-process up to 50 images at once, then download them all in a single ZIP file.
