Watermark Adder

How to use this tool

1. Drop in the image you want to watermark.
2. Type your text — a name, handle, website, or copyright line.
3. Choose a position, or pick "Tiled" to cover the whole image, then adjust colour, opacity, size, and rotation. The preview is the real output, not an approximation.
4. Download the finished image.

Common mistakes to avoid

• Don't set opacity so low that the watermark is invisible — if it cannot be read, it is not attribution, and it will not deter anyone either.
• Don't place a corner watermark right at the edge if deterrence is the goal; it is the easiest thing in the world to crop off. Use the tiled option instead.
• Don't watermark your only copy. Keep the clean original — the output here is a new JPEG, and there is no way to remove the watermark afterwards.

Corner mark or tiled?

These are two different jobs. A corner mark is attribution: it says who made the image without getting in the way of looking at it, which is what you want for a portfolio piece or a photo you are happy to have shared as long as your name travels with it. It is also trivially removable — a crop takes seconds.

A tiled watermark is deterrence: repeated diagonally across the entire frame, it cannot be cropped out, and removing it means reconstructing the image underneath it. This is the right choice for proofs sent to clients before payment, or for images you are showing publicly but do not want reused. The trade-off is that it is genuinely intrusive — which is the point.

Why the watermark scales with the image

A watermark specified in fixed pixels breaks as soon as the image size changes: 24px text is bold and legible on a 600px thumbnail and a barely-visible speck on a 6000px photo. This tool sizes the text as a percentage of the image's shorter edge instead, so one setting produces a visually consistent result across every image you run through it — which matters if you are watermarking a batch and want them to look like a set.

Frequently asked questions

Does a watermark actually stop people using my image?

It stops casual reuse, which is most reuse. A determined person can crop or edit a watermark out, and AI inpainting has made that easier — so treat a watermark as a deterrent and an attribution mark rather than protection. A tiled, semi-transparent watermark across the whole image is much harder to remove cleanly than a small mark in one corner.

Where should I place the watermark?

A corner mark is unobtrusive and fine for attribution. If deterrence matters more than aesthetics, use the tiled option — it covers the whole frame, so removing it means reconstructing the image underneath rather than just cropping an edge.

Will the watermark stay proportional on very large or very small images?

Yes. The size setting is a percentage of the image's shorter edge, not a fixed pixel size, so the same setting looks the same on a 600px thumbnail and a 6000px photo.

What format is the output?

JPEG at 92% quality, which suits photographs. Note that a JPEG has no transparency, so if you started from a transparent PNG the transparent areas will become black.

Is my image uploaded to add the watermark?

No. The image is drawn to a canvas in your browser and exported from there. Nothing is sent to a server — which matters for client work and unpublished photography, exactly the material people most often want watermarked.

How GetByteRush compares

Most free tools for this online work the same way: you upload your file to their server, wait, then download the result — which means your file (and often your email, for a "free" account) sits on someone else's infrastructure. Here's the actual difference:
