Open a 360° photo from a 360 camera, a phone panorama or a 3D render and look around inside it. Drag or use the arrow keys to turn, scroll or pinch to zoom, tilt your phone with the gyroscope, switch to a little planet view, and get a ready-made embed snippet or a standalone viewer file to share.

Option 1: download a single HTML file with the viewer and your photo inside. It opens in any browser, offline, and can be uploaded to any web host.
Option 2: embed code for your website. Upload the 360 photo to your site, paste its address here and copy the snippet into your page. The image must be on the same site or served with CORS enabled.

How to use the 360 Panorama Viewer
Open a 360° photo by dropping it on the box, choosing it, or pasting it. A sample panorama is loaded so you can try the controls first.
Look around by dragging, using the arrow keys, or turning on the gyroscope on a phone. Zoom with the mouse wheel, a pinch, the + and - keys or the slider.
Switch the view to Little planet for a tiny-world effect, start auto-rotate, or go fullscreen.
Save a view with Download view (PNG) to share a normal photo of the angle you like.
Share the panorama: download a standalone HTML viewer, or copy the embed code for your website after uploading the photo there.
How a 360° photo is shown on a flat screen
An equirectangular panorama maps the whole sphere around the camera onto a rectangle: the horizontal position is the compass direction (longitude, 0-360°) and the vertical position is the angle above or below the horizon (latitude, +90° to −90°). That is why it is always 2:1 and why the top and bottom look heavily stretched. For every pixel on your screen the viewer computes the direction of the ray through that pixel, turns it by your current heading and tilt, converts it to longitude and latitude, and reads that point from the photo:
Normal view uses a rectilinear (gnomonic) projection, the same as a regular camera lens, so straight lines stay straight. The field of view is limited to about 110° before the edges stretch too much.
Little planet uses a stereographic projection centered on the point straight below the camera. It keeps shapes locally correct while showing up to the full sphere, which bends the horizon into a circle.

Tips: export 360 photos as JPG at high quality for sharing, keep the horizon level in your camera app or editor before exporting, and remove the tripod at the bottom (nadir) with a logo patch or a clone tool if you want a cleaner little planet.
Frequently asked questions
What kind of photo does a 360 panorama viewer need?
A full 360° photo is stored as an equirectangular image: a flat picture exactly twice as wide as it is tall (2:1), where the left and right edges meet and the top and bottom rows are the points straight up and straight down. 360 cameras such as Insta360, Ricoh Theta and GoPro Max, phone photo sphere modes and most 3D renderers export this format.
Why does my panorama look stretched or have gaps?
If the image is not 2:1 it does not cover the whole sphere. Phone panoramas often cover 360° horizontally but only part of the vertical view; when the photo contains GPano metadata the tool places it correctly and fills the rest, and very wide images are treated as a 360° strip. Ordinary wide photos that cover less than 360° will look stretched because they are not spherical images.
How do I use the gyroscope on my phone?
Open the page on a phone or tablet and tap Use gyroscope. On iPhone and iPad the browser asks for permission to use motion sensors; allow it. Then move the phone around you to look in that direction, as if through a window. Tap the button again to go back to touch control.
What is the little planet view?
Little planet is a stereographic projection looking straight down: the ground becomes a small round world and the sky wraps around it. It is a popular way to share 360 photos as a normal picture. Zoom out for a smaller planet and drag to spin it, then download the view as PNG.
How can I put a 360 photo on my website?
Upload the 360 photo to your website, paste its address into the embed section and copy the snippet into your page's HTML. The snippet contains a small WebGL viewer, so no plugin or external service is needed. The image must be on the same site or served with CORS enabled. Alternatively, download the standalone HTML file and upload it as its own page.
Is there a size limit?
The viewer shows the photo as a GPU texture. Most computers and phones handle 8192 × 4096 pixels (32 MP); if your device supports less, the photo is scaled down to fit and the info line says so. Larger originals still open, only with less detail when zoomed in.
Are my photos uploaded?
No. The photo is opened and displayed with WebGL directly in your browser. Nothing is sent to a server, so private 360 photos of homes or offices stay on your device.
Are all the tools on FreeToolCabin tested for quality and accuracy?
