Photos you worked hard to capture or design get freely stolen without attribution. On social media and e-commerce platforms, images spread fast — without watermarks, you easily lose control over your own work.
Suried Tools Watermark tool supports custom text watermarks with adjustable opacity, angle, font, and color — full-tile or single placement — all processed locally in your browser with no uploads.
01 Uploading Your Image
Open the Suried Tools Watermark page and drag your image into the upload area, or click to select a file. JPG, PNG, WebP, and other common formats are supported with no file size limit.
After uploading, the image immediately appears in the canvas area where you can preview all watermark effect changes in real time. Throughout the process, your image is never sent to any server.
02 Setting Text Watermark Content
In the watermark settings panel, enter your desired watermark text — brand name, website URL, or copyright notice. Chinese, English, and other languages are all supported.
You can choose the watermark font, size, and color. A clean, easily recognizable font is recommended, with a color that contrasts with the image content without being too distracting.
Keep watermark text short and punchy — brand names or URLs work best. Overly long text detracts from image aesthetics.
03 Adjusting Opacity and Angle
Opacity controls how visible the watermark is. Lower values make it subtler — preserving image aesthetics while remaining identifiable; higher values make it more prominent for stronger theft protection. 20%–40% opacity is recommended.
Angle settings rotate the watermark text diagonally (typically -45° or -30°), covering more area and making it harder to crop or remove.
The tool supports full-tile mode and single watermark mode. Full-tile mode evenly repeats the watermark across the entire image, ideal for scenarios requiring strong protection.
04 Previewing and Downloading the Result
All setting adjustments are reflected in the preview canvas in real time. Once satisfied, click the download button to save the watermarked image. The output format matches the original, maintaining optimal quality.
The downloaded image has the watermark permanently merged into pixels — it cannot be removed by simple operations. Keep a backup of the original for future use when a non-watermarked version is needed.
Zoom into the preview before downloading to ensure the watermark is clearly visible at different scales.
FAQ
Does image quality decrease after adding a watermark?
The tool does not recompress the image when adding watermarks, so output quality is essentially the same as the original. For JPG format, minimal quality loss is inherent to the lossy format but is virtually imperceptible to the human eye.
Can I use an image (logo) instead of text as a watermark?
The tool currently focuses on text watermarks — you can approximate a logo effect by choosing appropriate fonts and styling. Image watermark support is planned for future versions.
Is batch watermarking supported?
Yes. You can upload multiple images at once and apply the same watermark settings in one batch. After processing, preview each individually or download them all as a package.
How should I choose the watermark color?
Choose a contrasting color based on the image's dominant tones. Light images work well with dark gray or black watermarks; dark images work well with white or light gray. Lower opacity reduces the color's visual impact.
Is my image data safe? Will it be uploaded?
Completely safe. All image processing happens locally in your browser. Image data is never sent to any server. All data is automatically cleared when you close the page.
