Where should I place the watermark?

A corner is unobtrusive but trivially cropped out. A larger, low-opacity mark across the centre is much harder to remove, which is why proofs and samples use it. Choose according to whether the image is a portfolio piece or a proof.

Does a watermark actually protect my copyright?

It deters casual reuse and keeps your name attached when an image is shared, but it is not a legal mechanism and it can be removed by someone determined. Copyright exists whether or not the image is marked.

Can I use a logo image instead of text?

This tool applies text watermarks. For a logo, add it with Add Text as a wordmark, or composite the logo in a full image editor.

Why use AinnoBox for this

Opacity and rotation control let a mark be present without dominating, which is the difference between a usable portfolio image and a ruined one.
Batch mode applies an identical mark across a whole shoot, so a gallery looks deliberate rather than hand-assembled.
The watermark is drawn at the image's own resolution, so it does not turn soft or pixelated on a large photo.
Client proofs and unpublished work are precisely the images you should not upload to a free host to have them marked.
Free, unlimited, no sign-up — and no second watermark from us on top of yours.
