Frequently asked questions
No. The entire watermarking process runs in your browser using the HTML5 Canvas API. Your images never leave your device.
There's no hard limit — you can select as many files as you like. Very large batches (100+) may take a few seconds depending on your device's CPU speed.
Tile mode repeats the watermark across the entire image in a diagonal grid pattern, making it difficult to crop or remove. Ideal for protecting content before sharing online.
Only if you choose JPG or WEBP output with quality below 100%. PNG output is lossless. The default quality is 90%, which is virtually indistinguishable from the original.
