About Our Image Averaging & Stacking Tool

Ever wanted to capture that "silky water" look or make a crowded tourist spot look empty without using expensive filters? Our free online long exposure simulator uses the power of mathematics to achieve these professional results. By averaging multiple photos online, we can simulate a single long exposure.

The core principle is simple: random noise and moving objects vary from frame to frame, while the static landscape stays constant. When you stack photos online, the random elements are averaged out, leaving you with a crystal-clear, noise-free image that looks like it was taken with a high-end ND filter.

Noise Reduction by Stacking: Eliminate high-ISO grain for cleaner night shots.
Ghost Removal Online: Make pedestrians and traffic disappear from your cityscapes.
Silky Motion: Soften waterfalls and waves for a dreamlike artistic effect.
Zero Upload Privacy: As a secure image stacking no upload tool, your photos never leave your device.
Completely Free: Professional-grade simulation without the high software costs.

Frequently Asked Questions

What is image averaging?

Image averaging is a technique where multiple photos are combined by calculating the average pixel value for every coordinate. It's the best way to reduce noise by stacking photos.

How many photos should I upload?

For significant online image noise reduction stacking, we recommend at least 10 to 20 photos. For ghost removal from photos online, more frames increase accuracy.

Do I need a tripod?

Yes, for the best professional photo stacking tool free results, your camera should stay in the same position for all shots.

Is this tool private?

Yes. This is a private long exposure simulator. Everything happens in your browser's RAM; nothing is uploaded or saved on our servers.

Can this replace a real ND filter?

Mostly, yes! Stacking and averaging is a digital equivalent. While a real ND filter is better for long light trails, image averaging tool online is superior for noise reduction.
