Before converting, make sure your HEIC file opens correctly and isn't corrupted. A damaged source file will produce a poor conversion result.

Batch Convert for Efficiency

If you have multiple HEIC files, use the batch upload feature to convert them all at once rather than processing them one by one.

Preserve Original Files

Always keep your original files until you've verified the converted output is correct. Don't delete originals until you're satisfied with the results.
