Frequently Asked Questions
No. We built this tool prioritizing user privacy. The watermarking process utilizes native browser technologies, meaning your image never leaves your computer.
The best way to prevent cropping is to use the Tile Watermark feature. This will repeat your logo or text in a diagonal grid across the entire photo, making it impossible to crop out without destroying the image.
You can export your final image as a high-quality JPG, PNG, or WebP file.

Frequently Asked Questions
How do I add a transparent text watermark to my photo?
Upload your image to the Watermark tool, type your copyright text, and adjust the opacity slider to make it transparent so it doesn't obscure the main photo.
Is it safe to upload my proprietary photography to this tool?
Yes, it is completely secure. The watermarking process happens locally in your web browser. Your high-value images are never uploaded to an external server.
Can I upload a company logo to use as a watermark?
Yes, alongside text, you can upload a PNG logo file and overlay it onto your main image, adjusting its size, transparency, and position.
How do I repeat a watermark across the entire image (tiling)?
Use the 'Tile' or 'Repeat' setting in the tool. This will duplicate your text or logo in a diagonal pattern across the whole photo, making it impossible to crop out.
Is it possible for someone to remove the watermark later?
Once you download the watermarked JPG/PNG, the text is 'flattened' into the image pixels. While AI tools can attempt to remove it, a heavily tiled watermark is extremely difficult to erase cleanly.
Can I rotate the watermark text diagonally?
Yes, you can use the rotation slider to angle your text (e.g., 45 degrees), which is standard practice for protecting real estate or stock photos.
Does adding a watermark increase the file size?
Minimaly. However, the tool allows you to compress the final output image so it remains optimized for web sharing even after the watermark is applied.
Can I watermark multiple images at once?
Yes, our tool supports batch processing. You can configure your text or logo once and apply it uniformly to dozens of photos simultaneously.
