Frequently Asked Questions
What is HEIF format?
HEIF (High Efficiency Image Format) is a modern image format that provides better compression than JPEG while maintaining higher quality. It's the default format used by Apple devices for photos.
How do I convert images with Heifiy?
Simply drag and drop your images (JPEG, PNG, etc.) onto the Heifiy app window. The app will automatically convert them to HEIF format and save them to your chosen location.
What image formats does Heifiy support?
Heifiy supports most common image formats including JPEG, PNG, TIFF, BMP, and GIF as input formats, converting them all to HEIF.
Can I batch convert multiple images?
Yes! You can drag multiple images or entire folders into Heifiy, and it will convert all supported images in one go.
Is my data secure?
Absolutely! Heifiy processes all images locally on your Mac. Your images are never uploaded to external servers or transmitted anywhere. Complete privacy and security guaranteed.
Which macOS versions are supported?
Heifiy requires macOS 15.0 (Sequoia) or later. The app uses the latest Apple technologies and frameworks for optimal performance.
Can I adjust conversion quality?
Heifiy is designed to provide optimal quality automatically. The app uses Apple's built-in HEIF encoder to ensure the best balance between file size and image quality.
Where are converted images saved?
By default, converted images are saved in the same location as the original files. You can choose a different output directory in the app's preferences.
Troubleshooting
App won't open or crashes
Ensure you're running macOS 15.0 or later. Try restarting your Mac and reopening the app. If issues persist, try reinstalling Heifiy.
Images won't convert
Check that your images are in a supported format (JPEG, PNG, TIFF, BMP, GIF). Ensure you have write permissions to the output directory.
Conversion is slow
Large images or batch conversions may take some time. The app processes images using your Mac's built-in tools for best quality, which may be slower than other methods but ensures optimal results.
