Question 1

What is the difference between HEIF and HEIC?

Accepted Answer

HEIF is the format specification. HEIC is Apple's implementation. They're functionally identical — both use HEVC compression.

Question 2

Does flipping affect HEIF quality?

Accepted Answer

Flipping itself is lossless. Re-saving applies HEIF compression. Use "Image Quality (%)" at 85% or higher for best results.

Question 3

Can I compress while flipping?

Accepted Answer

Yes. Under "Image Compression," choose any method. HEIF is already efficient, so moderate compression maintains good quality.

Question 4

Can I also resize while flipping?

Accepted Answer

Yes. Under "Image resolution," set by percentage or keep original.

Question 5

Should I flip as HEIF or convert to JPEG?

Accepted Answer

Keep HEIF for Apple devices and modern platforms. For universal compatibility, HEIF to JPEG works everywhere.
