Is watermarking done locally?

Yes. All processing happens in your browser. Images never leave your device.

Can I batch watermark multiple images?

Yes. Enable Batch and select multiple files; the same settings apply to each image.

How do I keep layout stable with ads?

We wrap each ad in fixed‑size containers, so CLS stays near zero on load.

Can I strip metadata?

Exporting via canvas drops most EXIF; use the strip toggle for extra removal.

Watermark Studio — FAQ

Is everything local/private?

Yes. All processing runs in your browser; your images never leave your device.

What’s the best placement?

Bottom‑right or tiled at low opacity (25–45%) balances protection and aesthetics.

How do I avoid ruining the subject?

Use Outline + slight Shadow, then move the mark away from faces or key details. Try Tile for share‑safe previews.

Can I export transparent backgrounds?

Yes — choose PNG. JPG/WebP will flatten colors as usual.

J1nx: Hey you 👀—I’m J1nx. Ready to stir up a little trouble, or do you want to keep it PG today?
(Don’t worry, I’m good at both…)
