Why mark your work as DRAFT or PROOF?
When you share a file with a client or team, it is easy for them to assume it is final. A large DRAFT or PROOF mark removes that ambiguity. It protects you from a situation where a client publishes an unfinished design or uses a low-res photo without paying.
If you need to protect your final work from theft instead, try the copyright tool or the tiled watermark maker. For DRAFT and PROOF, use a centered mark with lower opacity.
Features of this draft watermark tool
Prevent accidental publishing
When you share early versions of a design or photo, a DRAFT mark makes it obvious that the work is not final. It prevents clients from using an unfinished file.
Clear communication
A big PROOF stamp instantly tells reviewers that this is a preview. It avoids confusion about whether the image is ready for print, web, or publishing.
Custom stamp styling
Use red for urgency or black for formal documents. Rotate the text slightly and lower the opacity to make it look like a real rubber stamp.
Private, runs in your browser
Your unreleased designs and client proofs are sensitive. They are not uploaded to our servers. The watermark is applied locally using HTML5 Canvas.
Tips for the perfect DRAFT stamp
- 1
Make the text large
A DRAFT watermark should be impossible to miss. Set the size to 10% to 20% of the image width so it covers a significant part of the center.
- 2
Use Red or Dark Grey
Red is the universal color for warnings and drafts. If the image has a lot of red, use a dark grey or black with slightly higher opacity.
- 3
Lower the opacity to 30% - 40%
You want the client to see the image clearly, but you do not want them to use the image without paying or approving it first. 30% opacity is usually perfect.
- 4
Place it in the center
Unlike a copyright mark that goes in the corner, a DRAFT stamp should go right in the middle of the image. This prevents anyone from cropping it out easily.
- 5
Rotate it slightly
A diagonal tilt (like -15 degrees) makes the text look like a stamped seal rather than just typed text. You can adjust rotation in the tool settings.
Who uses DRAFT watermarks
Photographers
Send low-resolution proofs to clients with a big PROOF stamp. Once they pay, send the clean, high-resolution files.
Graphic Designers
Share logo concepts, brochure drafts, or UI mockups with DRAFT on them so clients do not publish the unfinished version.
Copywriters and Marketers
If you are sharing visual ad concepts with the team, mark them as DRAFT to ensure no one runs the ads prematurely.
Architects and Engineers
Stamp CONFIDENTIAL or DRAFT on blueprints and 3D renders before sharing them with contractors or clients.
Legal and HR Teams
Mark internal documents or scanned forms with CONFIDENTIAL before circulating them to a wider group.
Students and Researchers
Add DRAFT to your thesis diagrams or research charts before submitting them for peer review.

Draft Watermark FAQ
Why add a DRAFT watermark?
When you share early versions of a design or photo, a DRAFT mark makes it obvious that the work is not final. It prevents clients from accidentally publishing an unfinished file or using it without paying.
How do I make it look like a real stamp?
Use the word DRAFT or PROOF, make the text size large (e.g., 15% of image width), set the color to red or black, and reduce opacity to 30%. Rotate it a few degrees for a classic stamp look.
Can I add the same stamp to many photos?
Yes, upload up to 20 photos and they will all get the same DRAFT mark. This is perfect for sending a whole gallery of client proofs.
Does it upload my images?
No. The stamp is drawn in your browser using HTML5 Canvas. Nothing is uploaded to a server, so your sensitive or unreleased work stays 100% private on your device.
Can I use a red stamp?
Yes. You can pick any color using the color picker. Red is the most common choice for DRAFT and CONFIDENTIAL stamps because it stands out and signals caution.
Can a client remove the DRAFT watermark?
A centered, semi-transparent watermark is very difficult to remove without ruining the image. While no watermark is 100% tamper-proof, this effectively prevents casual theft or accidental use.
Will the watermark hide my design?
If you use 30% opacity, the client can still see the design clearly, but they cannot use it in a final product. It is a balance between visibility and protection.
Is it free to use?
Yes. No sign-up, no watermark added by us, and no hidden fees. It is completely free for personal and commercial use.
Privacy note
The watermarking happens on your device. Your photos are read by your browser, drawn on a canvas and saved back to your device. They are not sent to ToolDeck servers. See our Privacy Policy for details.
