Does the tool strip metadata?

Yes. Re-encoding through the browser canvas produces a clean file without EXIF, including GPS. If you need metadata preserved, keep an unwatermarked master.

Can I match my existing signature?

Upload your signature as a transparent PNG and use logo mode. The aspect ratio is preserved automatically.

Is there a file size limit?

Your device's memory sets the limit. Start with a small batch on phones, and split large or high-resolution galleries into smaller sets. Export dimensions are capped at 12,000 pixels on the longest side.

Watermark client proofs without uploading them

Proof galleries get screenshotted, and portfolio images get reposted without credit. Watermarking a whole shoot takes one drag-and-drop here. Because the tool runs locally, you can mark unreleased client work without sending it to a third-party server.
