Frequently Asked Questions
Can I watermark multiple images at once?
Yes! Our bulk engine applies your chosen settings to every image in your queue and packages them into a ZIP file.
Will the watermark be permanent?
Yes. The watermark is physically burned into the pixel data of the exported image, making it difficult to remove without advanced AI tools.
Is there a limit on file size?
Since everything is processed locally, large high-res images depend on your device memory. We recommend batches under 100MB for best performance.
