Frequently Asked Questions

What is HEIC format?
HEIC (High Efficiency Image Container) is a modern image format developed by MPEG. It offers significantly better compression than JPEG while maintaining similar quality. Apple uses HEIC as the default photo format on iPhones and iPads since iOS 11.
Why convert JPEG to HEIC?
HEIC files are typically 40-50% smaller than equivalent JPEG files. Converting to HEIC saves storage space on Apple devices and iCloud. It also supports features like transparency and image sequences that JPEG cannot.
Can all devices open HEIC files?
Apple devices (iOS 11+, macOS High Sierra+) natively support HEIC. Windows 10/11 can open HEIC with the HEIF extension from Microsoft Store. Some Android devices also support HEIC. For maximum compatibility, keep JPEG copies.
Is there quality loss when converting?
The conversion process re-encodes the image, which may introduce minimal quality changes. Using higher quality settings (80-95%) preserves visual quality while still achieving smaller file sizes than the original JPEG.
Are my files safe?
Yes. All conversion happens in your browser using JavaScript. Your images are never uploaded to any server. Data is cleared when you close the page.
