How to use Add Watermark to Image

  1. 01

    Select your photo

    Choose a JPG, PNG or WebP from your device — it opens directly in your browser and is never uploaded.

  2. 02

    Type your watermark text

    Enter up to 64 characters — your name, brand or website — and see it rendered on the photo instantly.

  3. 03

    Adjust position, opacity and size

    Place the text in one of five positions, set its opacity from 10–100% and its size from 2–20% of the image, previewing every change live.

  4. 04

    Download the watermarked image

    Save the result in its original format. The text is burned into the pixels, so keep an unmarked original if you'll need one later.

Why choose our Add Watermark to Image

Photo never leaves your device

The watermark is drawn onto your image entirely in your browser, so there's no upload and no server copy of your original photo.

Full control over the look

Fine-tune text, position, opacity and font size until the watermark strikes the right balance between visible and unobtrusive.

Live preview, instant export

Every adjustment renders immediately, and the final image is ready to download the moment you're happy with it — no processing queue.

Free for unlimited photos

Because watermarking runs locally, there's no per-image cost — protect as many photos as you like.

No account required

Start watermarking immediately; nothing to register, verify or log into.

Settings guide

Watermark text (up to 64 characters)
Short text works best: a © symbol plus your name, brand or website. Long sentences shrink or overflow at larger font sizes, so keep it within the 64-character limit and as concise as possible.
Position (top-left / top-right / center / bottom-left / bottom-right)
Corner positions give a discreet credit line; the center position offers the strongest protection because it cannot be cropped out without destroying the photo.
Opacity (10–100%)
30–50% keeps the watermark subtle so the photo stays the focus; 70–100% makes it clearly visible and much harder to paint out. Start around 40% and adjust in the preview.
Font size (2–20% of image size)
The size scales with the image, so the watermark looks consistent at any resolution. Around 5% suits a discreet credit; 10–20% is a strong deterrent for photos shared publicly.

About the formats

JPG

JPG (also written JPEG) is the most widely used lossy image format for photographs, standardized by the Joint Photographic Experts Group in 1992. Practically every camera, phone, and image application can create and open it.

Its strengths are small file sizes for photos and universal compatibility across devices, browsers, and software. The trade-offs: lossy compression introduces artifacts, there is no transparency support, and quality degrades a little more with every re-save. Use JPG for photographs; choose PNG for screenshots, logos, or anything that needs sharp edges or transparency.

PNG

PNG is a lossless raster image format created in the mid-1990s as a patent-free replacement for GIF. It is the standard choice for screenshots, logos, UI graphics, and any image that needs transparency.

PNG preserves every pixel exactly and supports a full 8-bit alpha channel, so text and sharp edges stay crisp. The downside is size: photographs saved as PNG are far larger than the same image as JPG or WebP. Support is universal in browsers and editors, making it a safe default for graphics — just avoid it for large photo collections.

WebP

WebP is a modern image format developed by Google that supports both lossy and lossless compression, along with transparency and animation. At comparable visual quality it usually produces noticeably smaller files than JPG or PNG.

Every current browser supports WebP, which makes it an excellent default for web delivery. Outside the browser the picture is mixed: older desktop software, some email clients, and legacy systems may fail to open it. If a recipient cannot view a WebP file, convert it to JPG for photos or to PNG when transparency must be preserved.

Troubleshooting

Watermark is too subtle
Raise the opacity toward 100% and increase the font size. Moving it to the center also makes it far harder to ignore or crop out.
Watermark covers the subject of the photo
Switch from the center to a corner position and reduce the font size. Lowering the opacity a little also lets the image show through the text.
Text looks cut off or overflows the image
Long text at a large font size can exceed the image width, especially on narrow images. Shorten the text (it is capped at 64 characters) or lower the font-size percentage.

FAQ

Can the watermark be removed later?
No. The text is burned into the image pixels, so it cannot be cleanly removed afterwards — that is exactly what makes it effective protection. Always keep an unwatermarked original for yourself.
Is my image uploaded anywhere?
No. The watermark is drawn onto your image entirely in your browser, never uploaded. The file stays on your device the whole time.
What can I customize?
The watermark text (up to 64 characters), its position (top-left, top-right, center, bottom-left or bottom-right), its opacity (10–100%) and its font size (2–20% of the image size).
Is there a file size limit?
There is no upload limit because processing is local. Very large images are limited only by your device's memory, and watermarking a single file is free.
Can I add a logo image instead of text?
Not yet — the tool currently supports a text watermark only, up to 64 characters. You can still create a strong mark using your name, a © symbol or your website, combined with the position, opacity and size controls.
Will watermarking reduce my image's quality?
There's no extra quality loss beyond a normal re-save: the watermark text is drawn onto the existing pixels, so the underlying photo detail is unchanged. A JPG re-encode is very slightly lossy as usual, while PNG and WebP stay lossless.
Is watermarking free, and is there a limit on how many photos I can mark?
It's free and unlimited. Because the watermark is drawn entirely in your browser, there's no upload, no account, and no cap on how many photos you can watermark.
