Supported formats in detail
Input, common image formats
| HEIC | The standard format of the iPhone since 2017. Saves space but many programs cannot open it. |
|---|---|
| HEIF | The same technique as HEIC with a different extension. Newer Android devices use it as well. |
| AVIF | A modern format for the web, very small. Older programs cannot read it. |
| JPG, JPEG | The most widely used image format. Opened by practically every device and service. |
| PNG | Lossless and with transparency. Suitable for screenshots, logos and graphics with text. |
| WEBP | A format from Google, common on websites. Rejected by some older programs. |
| TIFF, TIF | A format from printing and archiving, also used by scanners. The files are large. |
| GIF | The oldest of these formats, limited to 256 colours. Animations are taken from the first frame. |
| BMP | An uncompressed format from the Windows world. Very large files with no advantage in quality. |

Frequently asked questions
Do I have to install the program?
No. It is a single file that runs without installation. It changes no system settings and requires no elevated privileges.
Are my images uploaded?
No. Processing happens entirely on your device. A connection is established only if you start the update check yourself, and only the program version is requested.
Why does Windows warn me on first start?
Windows treats new programs as unknown until the publisher has built up a reputation. The file is digitally signed; under More information you can see AIXI Digital GmbH as the publisher and continue.
What applies after the free period ends?
The program points this out and stops converting until you register. All files already created remain fully usable. There is no obligation to register.
