What Private Marker is
Private Marker is a browser-based tool for watermarking batches of photos and downloading the results as a ZIP file. Users can position, resize, rotate, and change watermark opacity with a real-time preview. Logo tools include AI background removal, smart cropping, and filters such as black and white, inversion, and embossing. The maker says image processing happens locally in the browser and photos are not uploaded to its servers. The watermark tool supports JPG, PNG, and WEBP, and offers Standard (85%) and Maximum Quality (100%) export options while preserving original resolution. The free plan allows up to 50 watermarked photos per batch without an account, or 100 with a free account. Other browser-based tools remove photo metadata, compress images, and convert them to WebP. The metadata tool supports JPG, PNG, WEBP, HEIC, and HEIF, removing common EXIF, XMP, IPTC, GPS, date, and device information. Google sign-in can save a logo and preferred settings. Private Marker works in web and mobile browsers.
