❓ FREQUENTLY ASKED QUESTIONS :

Q: What type of images does this extension support? 
A: It supports equirectangular 360° images in JPG, PNG, and WebP formats. These are the standard output from 360° cameras like Insta360, Ricoh Theta, GoPro MAX, and drone panorama modes.

Q: Does this extension upload my photos to the internet? 
A: No. Your images are processed entirely on your own device. Nothing is uploaded, transmitted, or stored outside your browser.

Q: Can I use this extension offline? 
A: Yes. Once installed, the viewer works fully offline. No internet connection is required to open and explore your panoramas.

Q: What is equirectangular format? 
A: Equirectangular is the standard format for 360° photos. The image looks like a stretched, distorted rectangle when viewed flat — but when projected onto a sphere, it shows a complete panoramic view in every direction.

Q: Does it support 4K or 8K panoramas? 
A: Yes. There is no resolution limit enforced by the extension. High-resolution images up to 8K (8192×4096) are supported, depending on your device's GPU.

Q: What is Little Planet mode? A: Little Planet (also called Tiny Planet) is a creative effect that transforms your 360° panorama into a small spherical planet. It uses stereographic projection and animates smoothly when toggled on or off.

Q: Can I save a screenshot of my current view? 
A: Yes. Press the Snapshot button or use Shift+S to download the current view as a high-quality PNG file.

Q: What cameras are compatible with this viewer? 
A: Any camera that outputs equirectangular 360° images will work — including Insta360, Ricoh Theta, GoPro MAX, DJI Osmo, Samsung Gear 360, and photo-stitching software like PTGui, Hugin, and Adobe Lightroom.

Q: Does this work on Mac, Windows, and Linux? A: Yes. It runs in Google Chrome on any operating system — Windows, macOS, Linux, and ChromeOS.

Q: Is this extension free? 
A: Completely free, with no ads, no premium tier, and no limitations. If you find it useful, you are welcome to support the developer via Ko-fi or UPI.

Q: Why use this instead of an online 360° viewer? 
A: Online viewers require you to upload your photos to a third-party server. This extension keeps everything on your device, so your personal or professional photos are never exposed.
