常見問題
Are my photos uploaded to a server?
No. The watermark is rendered entirely in your browser, so your photos never leave your device.
Can I add the same watermark to multiple photos at once?
Yes. Upload multiple photos, configure the watermark once, then click "Download all" to process every photo with the same settings.
Will the watermarked photo lose quality?
Photos keep their original resolution. JPG and WebP use a high-quality encoder; choose PNG for fully lossless output.
