How this tool works
Check the text or logo placement against light and dark areas before exporting at full resolution. The preview is reduced for responsiveness. A watermark can identify a sharing copy, but does not prevent copying or establish legal ownership.
Choose supported files, review settings, process on your device, and inspect the output before downloading. Conversion may increase file size or change color representation. Re-encoding generally drops original metadata.
Transparency is supported in PNG and WebP. Inspect the preview and compare details before sharing.
