Question 1

What is ImageMark?

Accepted Answer

ImageMark is a free, open-source watermark tool for images. Add text or logo watermarks in your browser — no account, no uploads to our servers, no limits.

Question 2

How do I get started?

Accepted Answer

Open the watermark tool, drag in your images (or click to choose files), set your text or logo, adjust position and style, then download. You can process many images at once and download them as a ZIP.

Question 3

Is ImageMark really free?

Accepted Answer

Yes. ImageMark is free for everyone, forever. There are no subscriptions, credits, or paywalls. The project is open source — you can run it yourself or use imagemark.app.

Question 4

Is my data private and secure?

Accepted Answer

Yes. All watermarking runs in your browser. Your images are not sent to ImageMark servers for processing. We do not store your files.

Question 5

What image formats are supported?

Accepted Answer

JPEG, PNG, GIF, WebP, BMP, TIFF, and SVG. Processing happens locally in your browser.

Question 6

Can I watermark multiple images at once?

Accepted Answer

Yes. Upload as many images as you like, apply the same watermark settings to all of them, then download individually or as one ZIP file.

Question 7

How much can I customize my watermark?

Accepted Answer

Use text or a logo, pick from nine positions or set custom placement, and control size, opacity, rotation, font, and color.

Question 8

Will watermarking reduce image quality?

Accepted Answer

Watermarks are rendered at full resolution on a canvas. Your originals on disk are never modified — only the files you download are new exports.

Question 9

Do I need to create an account?

Accepted Answer

No account, email, or sign-in. Open the site and start watermarking.

Question 10

Is ImageMark open source?

Accepted Answer

Yes. The code is public on GitHub. You can contribute, report issues, or self-host the app for your team.
