What Is the Watermark Image?
How Is the Watermark Image Calculated?
The image is drawn onto a canvas at its full resolution, then your watermark text is drawn on top at the position you selected — a corner, an edge midpoint, or dead center — optionally rotated 45 degrees, at the opacity you set. The preview updates live as you adjust any control, and the downloaded file matches exactly what's shown.
Watermark Image Example
Entering "DRAFT" at 30% opacity with Position set to Center and rotation on stamps a large, translucent diagonal "DRAFT" across the middle of the photo; switching to Bottom Right with rotation off instead places a small, upright "DRAFT" label in the corner.
How to Use the Watermark Image
Step 1
Click the upload area or drag and drop an image onto it.
Step 2
Enter the watermark text — press Enter for a second line if you want a multi-line stamp.
Step 3
Choose a position and whether it should rotate diagonally.
Step 4
Adjust font size, opacity, and color while watching the live preview.
Step 5
Click Download to save the watermarked image.
Benefits
- Marks a photo as draft, sample, or copyrighted without installing any software.
- Processes everything locally in your browser — images are never uploaded anywhere.
- Live preview shows exactly how the watermark will look before you download.
Common Watermark Image Scenarios
Scenario 1
Marking preview photos with SAMPLE before sending proofs to a client.
Scenario 2
Stamping a copyright notice or website name across shared images.
Scenario 3
Labeling a screenshot as CONFIDENTIAL before sharing it internally.
Understanding Your Result
The downloaded image is the same resolution and content as the original, with your watermark text drawn at the position, rotation, and opacity shown in the live preview.
Tips
- Lower opacity (20-35%) keeps the watermark visible without hiding the photo underneath.
- Center + diagonal reads as a classic full-image stamp; a corner position with rotation off reads more like a small label.
- The default font size scales with the image, but feel free to adjust it — the live preview updates instantly.
Common Mistakes
- Setting opacity too high, which can hide the photo underneath.
- Using very long watermark text in a corner position, which can run off the edge of the image.
- Forgetting to check the live preview before downloading.
Frequently Asked Questions
Are my images uploaded to a server?
No, all processing happens locally in your browser using the Canvas API — your images never leave your device.
Can I add more than one line of watermark text?
Yes — press Enter in the watermark text box to start a new line. All lines are stacked and centered/aligned together.
Can I use an image or logo as a watermark instead of text?
Not in this version — only text watermarks are currently supported.
Can I remove a watermark this tool added?
Not with this tool — once downloaded, the watermark is part of the image's pixels. Keep your original file if you might need an unwatermarked copy later.
What opacity is best for a watermark that doesn't distract from the photo?
A lower opacity (often in the 20-40% range) is common for photography watermarks, keeping the mark visible for attribution without overpowering the image itself.
Can I preview how the watermark looks before downloading?
Yes — this tool includes a live preview so you can adjust text, position, rotation, and opacity before finalizing your download.
Should I watermark the center or corner of an image?
Corner or edge placement is common since it's less intrusive to the main subject, while center placement makes the watermark harder to crop out — the right choice depends on how strongly you want to protect against unauthorized use.
Does watermarking reduce the image's quality?
The watermark itself is an added overlay rather than a quality-reducing process, though the final export step (especially if converting to a lossy format like JPEG) can involve standard compression.
Can I save a watermark preset to reuse on multiple images?
Check whether the tool remembers your last-used settings — most browser-based tools require re-entering your watermark preferences for each new image unless a preset-saving feature is specifically offered.
Important Information
Images are read and watermarked locally in your browser and are never uploaded to a server.
