FAQ
Häufig gestellte Fragen
Will my image be uploaded?
No. The browser reads, composes, and exports your image locally with the File API and Canvas.
Can I add my own logo?
Yes. Switch to Logo, then choose a PNG, SVG, JPG, or WebP image. Transparent PNG or SVG files work best.
Why does my JPG have a white background?
JPG does not support transparency, so transparent pixels are exported with a white background. Choose PNG or WebP when transparency matters.
Can I watermark multiple images?
This page is designed for quick single-image editing. A batch workflow can be added as a separate tool because multiple large images use more browser memory.
