Feature-packed

PhotoStack can import multiple images from your local storage, then resize them, crop, add a watermark, remove EXIF data, and more. When you're done, the images can be exported to individual files or packaged in a ZIP file for easy sharing.

Powerful watermarking

PhotoStack can create and save custom watermarks to protect your images. You can set the image, positioning, opacity, size, and more. If you've ever used Adobe Lightroom, you'll feel right at home.

Watermarks are saved in your browser's storage for later use, and you can export them to a file for use on other browsers or devices.

Free as in freedom

PhotoStack doesn't lock you down to certain platforms or require a monthly subscription. It runs on everything with a modern web browser.

The PhotoStack source code is also available on GitHub under the GPLv3 license.

Privacy first

All image processing is done locally in your browser. Your images are never uploaded anywhere, and the only data collected by PhotoStack is basic analytics.

Offline support

PhotoStack can function entirely offline on most browsers. When you run PhotoStack for the first time, the app is saved to your device's storage, so typing in "photostack.app" will always work — even when you're away from Wi-Fi.

Wide compatibility

PhotoStack works on any modern browser or platform that supports modern web features, including Chrome, Firefox, Opera, Microsoft Edge, and others. For devices and browsers that aren't up-to-date, you can still use PhotoStack Classic.
