Batch Watermark Photos

How to watermark many photos at once

Open your photos

Choose or drop all the photos you want to mark. The first one opens in the preview.

Set up the watermark

Type your @handle or choose a logo, then pick the position, size, opacity and margin.

Save them all

Press Save. One photo downloads on its own; several come as a ZIP with every photo marked the same way.

How the watermark is placed

Size and margin are measured against each photo's shorter side, not its pixel count. A 25% watermark is a quarter as wide as the photo's short edge whether it's a tall portrait, a wide landscape or a square, so a mixed set looks consistent.

Phone photos are often stored sideways with a note saying which way is up. Each photo is turned upright before it's marked, so the watermark lands in the corner you see on your phone. Photos keep their full resolution and are saved as high-quality JPG; PNGs stay PNG so transparent areas survive. The saved copies carry no camera details or location.

A corner watermark is easy to crop out. If you're sharing work that gets reposted without credit, Tiled repeats the mark diagonally across the whole picture: lower the opacity to keep the photo enjoyable.

Frequently asked questions

Are my photos uploaded?

No. Every photo is marked in your browser and saved straight to your device. Nothing is sent anywhere.

How many photos can I watermark at once?

There's no set limit. Photos are processed one at a time to keep memory low; on a phone, a few dozen at a time works well.

Where should a watermark go on Instagram?

Keep it away from the very edges: Instagram's grid crops posts to 3:4 (as of October 2026), and Stories and Reels put buttons over the bottom and right. A margin of 4–6% keeps it clear of most crops.

Can I watermark HEIC photos?

If your browser can open them. Safari on iPhone and Mac can; on other browsers, export the photos as JPG first. The watermarked copies are saved as JPG.

Does a watermark stop people stealing my photos?

It makes reposts carry your name, and a tiled mark is hard to remove. A determined person can still crop or edit a corner mark away, so use tiled for work you sell.
