Frequently asked questions
What is an equirectangular panorama? expand_more
It is a 360° image in a 2:1 format, twice as wide as it is tall. It is used for virtual tours, 3D renders and spherical photos. If the camera was slightly tilted, the horizon may appear slanted.
How do I correct my panorama's horizon? expand_more
Add your panorama to the tool. It analyzes the image and suggests a leveled version, then you can compare before and after and download the result.
Are my images sent to a server? expand_more
Yes. Unlike fully local tools, this one uses server processing to level the horizon. Your images are temporarily hosted on servers in France, then automatically deleted within 24 hours.
Which formats are supported? expand_more
You can import JPG or WebP panoramas. The image must use a 2:1 format to be processed correctly.
Does processing change image quality? expand_more
The image is recalculated to correct the horizon. You can choose a lighter setting for the web or a setting closer to the original when quality is the priority.
Can I process multiple panoramas at once? expand_more
Yes. Add several files, start processing, then download results one by one or get the complete batch.
How long does processing take? expand_more
Processing usually takes a few seconds per image. Very large panoramas may take a little longer.
Why are some panoramas leveled incorrectly? expand_more
The tool looks for cues in the image to estimate what should be straight. If the panorama contains many tilted, curved or ambiguous elements, it may be wrong. Always check the result before using it.
Can I keep the file information? expand_more
Yes. Metadata is automatically preserved on every export, including the date, GPS location and device model.
Do I need an account? expand_more
No for occasional use. Pro access is only for regular use or larger volumes.
Does the tool work offline? expand_more
No. This tool needs an internet connection because leveling is performed on a server.
Is 360° panorama leveling free?expand_more
Yes, 360° panorama leveling is free and requires no sign-up. To process large volumes or use it regularly, switch to Pro.
