Frequently Asked Questions
Will the watermark obscure the image content?
You can adjust opacity to make the watermark semi-transparent, protecting copyright without hurting viewing.
Does it support batch processing?
Currently it processes one image at a time. After processing, settings are kept, so uploading the next image automatically applies the same watermark.
Are my images uploaded to a server?
No. All watermark compositing happens locally in your browser. Images and text are never uploaded.
Which output formats are available?
PNG, JPG and WebP. PNG is lossless and preserves detail, while JPG is smaller in size.
