Watermark Tool — FAQ
Can I watermark 50 images at the same time?⌄
Yes. Upload up to 50 images, configure your watermark once, and click Apply. Every image gets the same watermark applied in a single batch operation entirely within your browser.
Can I use my own logo as a watermark?⌄
Yes. Enable the "Logo watermark" option and upload any PNG image. We recommend a PNG with a transparent background so it blends naturally onto your photos. The logo is automatically scaled to 20% of the image width.
What positions can I place the watermark?⌄
You can place the watermark in any of 5 positions: top-left, top-right, bottom-left, bottom-right, or center. You can also rotate it at any angle from -45° to +45° — useful for a diagonal watermark pattern.
Does the watermark reduce image quality?⌄
Output images are saved as JPEG at 92% quality, which is visually lossless for photos. The watermark is drawn on top using the Canvas API with adjustable opacity — the original pixel data of your image is not otherwise altered.
Is this tool really free with no hidden limits?⌄
Yes. There is no file count limit per session, no size limit imposed by our tool (only your browser memory), no account required, and no watermark from us on the output images.
