JPG to HEIC Converter

1. Upload one or more JPG files (up to 50 MB total).
2. Click 'Convert to HEIC' — conversion finishes in under 3 seconds per image.
3. Download HEIC files individually, or grab all converted images as a ZIP.

HEIC files are typically 40-50% smaller than the equivalent JPG. Converting JPG to HEIC can reclaim gigabytes of storage on an iPhone or Mac — at the cost of reduced compatibility outside Apple's ecosystem.

If you have a large library of JPG photos taking up space, HEIC's HEVC-based compression can cut your storage footprint by 40-50% with no visible quality loss. This is especially useful for iPhone and Mac users who want to reclaim space, since macOS and iOS have native HEIC support. Note that HEIC is not natively supported on Windows, Android, older browsers, or legacy software — so JPG-to-HEIC is a storage optimization play, not a compatibility play. Use it when you know your destination (iPhone, iPad, Mac, iCloud) supports HEIC.

The converter decodes the JPG image and re-encodes it using the HEVC (H.265) codec inside an HEIF container. Typical output is 40-50% smaller than the source JPG at the same visual quality. EXIF metadata (camera, GPS, timestamp) is preserved. Transparency is not applicable to JPG input, so HEIC output from JPG never has an alpha channel.

• Reducing iPhone or iPad photo library size by 40-50%.
• Freeing storage on macOS without visible quality loss.
• Preparing photos for iCloud Photos (which uses HEIC by default).
• Shrinking a large JPG archive before uploading to iCloud or Dropbox.
• Preparing images for sharing via iMessage (native HEIC support).
• Reducing the size of JPG screenshots or scans stored on Apple devices.
• Optimizing a JPG-heavy photo library before backing up to Time Machine.

HEIC uses HEVC-based compression which is significantly more efficient than JPG's DCT. The output is visually indistinguishable from the source JPG at normal viewing conditions while being 40-50% smaller. Some minor quality loss is unavoidable because both formats are lossy, but at typical viewing distances the difference is not perceptible. For archival of critical photos, keep the original JPG — converting to HEIC is a one-way compression.

• HEIC is not natively supported on Windows 10 and earlier, Android, or older browsers.
• Some legacy software (Photoshop CS6, older GIMP) cannot open HEIC files.
• Repeated JPG → HEIC → JPG round-trips accumulate lossy artifacts.
• Very large JPGs (over 50 MB) are rejected.
• HEIC files can be problematic when shared via email or WhatsApp to non-Apple users.

• HEIC opens natively on iOS 11+, iPadOS, macOS High Sierra+, and macOS Big Sur+.
• Windows 10/11 can open HEIC with the free HEIF Image Extensions from the Microsoft Store.
• Native support in Photos, Preview, and modern Adobe apps (Photoshop CC, Lightroom CC).
• Not supported by most Android devices without third-party apps.
• Not supported by legacy browsers (Internet Explorer, older Chrome/Firefox).

• Use JPG → HEIC when your destination is iPhone, iPad, or Mac — HEIC is native there.
• Don't use HEIC if you plan to share with Android or Windows users without a converter.
• Keep the original JPG if the photo is irreplaceable — the conversion is one-way lossy.
• Batch-convert up to 50 MB at once for bulk storage optimization.
• HEIC files sync seamlessly with iCloud Photos — no conversion needed on Apple devices.

HEIC file won't open on Windows 7

HEIC requires Windows 10 with the HEIF Image Extensions installed, or Windows 11 natively. Windows 7 has no HEIC support. If you need Windows 7 compatibility, keep the original JPG.

HEIC file won't attach to Gmail or Outlook

Some older email clients strip HEIC attachments. Convert back to JPG, or use HEIC-to-JPG conversion for recipients on non-Apple platforms.

Converted HEIC is not much smaller than the JPG

HEIC's advantage comes from HEVC compression of raw image data. If the source JPG was already heavily compressed (low quality), HEIC cannot compress it much further. Original JPGs at 95-100% quality will compress the most.
