Add Watermark to Image

About this tool

This free Add Watermark to Image tool stamps a text or logo watermark onto your photo so you can protect and brand it before sharing. Pick a corner or the center, set the opacity, size and rotation, or tile the mark across the whole image — and watch the live preview update instantly.

Everything runs in your browser — your image is never uploaded to a server.

Features

• Text or logo — type a caption (© your name) or upload your own logo/PNG
• Full control — position grid, size, opacity, rotation and font
• Tile mode — repeat the watermark across the whole picture so it can't be cropped out
• Live preview — see every change before you download
• PNG, JPG or WebP output, full image quality

Making a watermark that actually holds up

The default instinct is a small mark in a bottom corner, and it is the easiest one to defeat: a crop removes it and nothing about the picture looks wrong afterwards. Anything you genuinely mind losing is better served by a mark that overlaps the subject.

Tiling is the strongest option here. Repeated across the whole frame, the mark cannot be cropped away without cropping away the photo, and removing it means repairing every copy rather than one.

Opacity is the real trade-off. Faint enough to ignore is also faint enough to paint out; heavy enough to be unremovable is heavy enough to spoil the image. Somewhere around 40–60% over a busy area is usually the sensible compromise — visible, awkward to clone out, still leaves the photo worth looking at.

Rotation helps for the same reason. A diagonal mark crossing the middle of the subject is far harder to repair than horizontal text lying in an empty margin.

None of this is protection in a strict sense. A determined person with good software can remove any visible watermark. What a good one does is make casual reuse — the screenshot, the re-post, the lifted product shot — more trouble than it is worth.

Common uses

• Protect photos before posting them online
• Brand product shots, screenshots or artwork with a logo
• Mark images as a draft, sample or proof

How to use it

• Upload an image — click the upload area or drag and drop a JPG, PNG or WebP
• Choose Text or Logo — type your watermark text or upload a logo image
• Adjust it — set the position, size, opacity and rotation (or turn on tiling)
• Download — save your watermarked image

Good to know

• Works on Windows, macOS, Linux, ChromeOS, and on phones and tablets — it is a web page, and your photo stays on your device
• The image is written back at its full original resolution, not a downscaled preview
• Choosing JPG flattens transparency onto a white background, because JPG has no transparency. Pick PNG or WebP if your image has transparent areas you need to keep
• A logo with a transparent background works properly — upload a PNG and only the logo itself is drawn
• JPG and WebP are saved at high quality, so a watermarked photo looks like the original with a mark on it, not like a re-compressed copy
• The preview is the real thing at a smaller size — what you see is what downloads
