Why Convert HEIC to AVI?

HEIC (High Efficiency Image Container) is Apple's default photo format on iPhone and iPad. It uses HEVC compression for smaller file sizes than JPEG. Converting HEIC photos to AVI creates a video slideshow, which is useful for playing iPhone photo slideshows on Windows PCs and legacy media players that support AVI, sharing photo compilations as video files without requiring HEIC-compatible viewers, creating video presentations from iPhone photos for devices that don't support HEIC, and embedding photo sequences in legacy video editing workflows that require AVI input.

Why is MPEG-4 the default codec for AVI?

MPEG-4 is the default video codec for AVI output, with MP3 as the default audio codec. This combination provides broad compatibility with Windows Media Player and legacy media players. You can change to H.264 under Video Codec for better compression.

Why is the Trim option not available?

Trim is hidden for image-to-video conversions because there is no existing video timeline to trim. Control the video length by adjusting Image Duration and the number of HEIC photos you upload.

Can Windows open HEIC files directly?

Windows 10/11 can open HEIC files with the free "HEIF Image Extensions" from the Microsoft Store. However, many older Windows systems and applications don't support HEIC. Converting to AVI creates a universally playable video.

How do I create a slideshow from iPhone photos?

Upload your HEIC photos, select "Merge images" under Merge Strategy, set Image Duration to 3-5 seconds, and choose a Background Color. The tool combines all images into a single AVI video in upload order.

Should I use AVI or MP4 for my slideshow?

AVI is best for legacy Windows systems and older media players. For modern devices and web sharing, use HEIC to MP4 instead — MP4 with H.264 plays on every current device and browser.
