About Image Watermark

What this page solves

Image Watermark solves the privacy and friction problem of typical online tools — it never uploads, never asks for a signup, and runs in your browser.

Image Watermark is a free in-browser image tool that lets you add text or image watermarks to photos without uploading your photos to any server. It is built for designers, content creators, marketers, and everyday users who need quick, private image edits — whether you are preparing assets for a website, resizing photos for social media, or compressing files before sending them by email. All processing uses your browser's Canvas and Web APIs, so your images stay on your device the entire time. Image Watermark loads as a small bundle and is interactive within a second on mid-range phones, so it is practical to use it from a phone while away from a desk. Nothing you load into Image Watermark is uploaded: the file or text is read with the browser's own FileReader and processed in page memory, so the work finishes even if your connection drops mid-task. Because the processing is local, Image Watermark is usable on locked-down corporate laptops and school networks where uploading work files to a third-party service is a policy violation. There are no watermarks, no quality compromises from third-party servers, and no waiting in upload queues. Image Watermark is part of our Image Tools suite — a unified set of tools for every step of an image workflow. If you also need a complementary utility, try our Image Resizer. It is free, has no signup, and works with the formats you actually use: JPG, PNG, WebP, GIF, SVG, and BMP.

Frequently asked questions

Can someone remove my watermark?

Yes, with effort. Content-aware fill in image editors removes small marks convincingly, and there are automated tools for it. A watermark makes casual copying inconvenient and asserts ownership visibly. It is not protection, and treating it as such leads to disappointment.

Where should I position it?

Across the centre or tiled is hardest to remove but most intrusive. A corner is unobtrusive but trivially cropped. For portfolio work where the image must still look good, a corner mark at low opacity is the usual compromise.

Does watermarking reduce image quality?

The image is re-encoded, which costs a small amount of quality at high quality settings. Nothing you would notice, but do work from your original rather than repeatedly watermarking an already-processed file.

Can I use a logo instead of text?

This tool handles text. For a logo, use Add Text to Image with a transparent PNG, or composite it in an image editor.

How to use Image Watermark?

1) Open the tool. 2) Enter or upload your input. 3) Get your result instantly. Everything happens locally — nothing is uploaded.

When should I use Image Watermark?

Use Image Watermark whenever you need a fast, private, browser-based way to add text or image watermarks to photos.

Is Image Watermark safe?

Yes. Image Watermark runs 100% in your browser. Inputs are never uploaded, stored, or logged — safe for confidential content.

Will quality be affected by Image Watermark?

Quality is preserved unless you explicitly choose a lossy format or low quality setting.

What formats does Image Watermark support?

Image Watermark supports JPG, PNG, WebP, GIF, BMP and SVG (where applicable)

Is Image Watermark free?

Yes — Image Watermark is completely free, with no registration, no watermarks, and no usage limits.

Are my images uploaded to any server?

No. Image Watermark processes images entirely in your browser using the Canvas API. Your photos never leave your device.

What image formats does Image Watermark support?

Image Watermark works with all common web formats including JPG, PNG, WebP, GIF, SVG, and BMP, depending on the operation.

Will I lose quality?

Image Watermark uses the browser's native image pipeline. Where compression is involved, you can usually control the quality level — otherwise the output is lossless.

Is there a file-size limit for images?

Image Watermark works on anything that fits in browser memory — comfortably up to 50 MB on a modern laptop, 20 MB on a phone. For larger panoramic or multi-gigapixel files, downscale first with a desktop editor.
