Private Image Watermark Tool for Text and Logos
Upload any JPG, PNG, or WEBP image and apply text or logo watermark with live export. This version is fully client-side for speed and privacy.
An image watermark tool adds visible text or logo marks to photos, screenshots, mockups, and review drafts.
This tool runs locally in your browser, so your source image does not need to be uploaded before export.
Choose readable watermark text
Use short brand names, draft labels, project names, dates, handles, or review status notes.
Match opacity to the goal
Use subtle opacity for ownership marks and stronger opacity for drafts, samples, or confidential review images.

What you can do next:
- Use this free local tool for quick copyright marks and social media proofing.
- Pair it with Image Cropper or Image Compressor when preparing assets for publishing.
Client previews and drafts
Add draft, sample, or brand text before sending mockups, product shots, screenshots, or creative previews.
Social and marketplace assets
Place a subtle logo or handle on images that may be reposted, forwarded, or separated from the original page.
Internal reviews
Mark screenshots with project names, status labels, or team identifiers before they move through docs and chat threads.
Example, Assumption, and Limitation
A 30% opacity corner logo works well for preview images. The tool assumes you want a visible mark; it is not a guarantee that an image cannot be copied or cropped.
Watermark screenshots
Add project names, draft labels, or confidential review notes before sharing screenshots in docs or chat.
Protect mockups
Place a visible brand mark on mockups, creative previews, and product concepts sent for review.
Brand social images
Add a subtle logo or handle to images that may be reposted, downloaded, or separated from the source page.
Mark product photos
Apply text or logo marks to marketplace images, internal catalogs, and sample product shots.
Is this a private image watermark tool with no upload?
Yes. The image is loaded, watermarked, and exported in your browser. It does not need to be uploaded to a server.
Does the image watermark tool upload my image?
No. The source image is processed in your browser, so the original file and exported result stay on your device.
Can I watermark screenshots and mockups?
Yes. You can watermark screenshots, mockups, product photos, social images, and review drafts as JPG, PNG, or WEBP files.
Should I use a text watermark or logo watermark?
Use text for quick draft labels, names, dates, or review status. Use a logo when you want a reusable brand mark across product images or campaign assets.
What opacity should I choose?
For subtle ownership marks, start around 20% to 35%. For review drafts or sample images, use a stronger opacity so the label remains visible after compression.
Can watermarking fully prevent image reuse?
No. A watermark is a visual deterrent and context marker, not a technical protection system. It is best paired with sensible sharing and licensing practices.
