Frequently Asked Questions

Why should I watermark my images?

Watermarking helps protect your intellectual property, prevents unauthorized use of your photos, and provides clear branding for your content when shared on social media.

Can I customize the watermark text?

Yes! You can enter any text you like, and adjust its opacity to ensure it's visible without distracting from the main image content.

Is it possible to remove a watermark later?

Once a watermark is 'baked' into the image pixels and downloaded, it cannot be easily removed without professional editing software. Always keep a backup of your original un-watermarked photo.

What image formats are supported for watermarking?

We support adding watermarks to JPEG, PNG, and WebP images.
