Questions about image watermarks
How do I add an image watermark to a photo?＋
Upload your photo as the background, then upload your watermark image as the overlay. Resize it, place it on the photo, adjust opacity, and export the result as a PNG.
Can I use my logo as a watermark image?＋
Yes. Upload your logo image as the watermark. Transparent PNG logos work especially well for clean watermark placement.
Does this tool add text watermarks?＋
No. This page is for image watermarks, such as logos, signatures, or transparent PNG graphics. To use a text-style watermark, create it as an image first and upload that image.
Can I watermark many photos at once?＋
No. PicOverlay edits one image at a time in your browser and does not include batch watermarking.
Can I tile a watermark across the whole photo?＋
The overlay tool can repeat an overlay image as a tile pattern. For simple corner or center watermark placement, use the normal image overlay controls.
Are my photos uploaded while watermarking?＋
No. The editing runs locally in your browser, so your photo and watermark image stay on your device.
