Convert HEIC to JPG on Mac
Every iPhone photo since iOS 11 is saved as HEIC, a format that most Windows PCs, websites, and apps still can't open. Converting to JPG gives you universal compatibility without visible quality loss. Whether you're uploading vacation photos to a website, emailing images to a client, or printing from a non-Apple device, JPG is the format that just works everywhere.

When to convert HEIC to JPG
Sharing iPhone photos with Windows users
Your family or colleagues on Windows can't open the HEIC files you send. Convert to JPG so everyone can view your photos without installing special software.
Uploading to websites and social media
Many platforms (including WordPress, Shopify, and some social media sites) still don't accept HEIC uploads. JPG is accepted everywhere.
Printing photos at a lab or kiosk
Most photo printing services require JPG format. Convert your iPhone photos before sending them to a print lab or using a retail photo kiosk.
Migrating from Apple Photos to another platform
Moving to Google Photos, Amazon Photos, or a NAS? Batch convert your HEIC library to JPG to ensure compatibility with any photo management system.

Frequently Asked Questions

How do I convert HEIC to JPG on Mac?
Open Picmal, drag your HEIC files or folders into the window, select JPG as the output format, adjust quality if needed, and click Convert. All processing happens locally on your Mac.
Does converting HEIC to JPG lose quality?
At 90-100% quality, the difference is virtually invisible to the human eye. A typical 12MP iPhone photo converts from ~2.5MB HEIC to ~3.5MB JPG at 95% quality with no visible artifacts. You can preview the quality before converting.
Can I batch convert hundreds of HEIC photos at once?
Yes. Picmal handles batch conversion natively. Drag entire folders with thousands of HEIC files and convert them all to JPG in one go. A batch of 500 iPhone photos typically converts in under 2 minutes on an M1 Mac.
Why can't I open HEIC files on Windows or in some apps?
HEIC is Apple's proprietary image format based on the HEVC codec. While macOS and iOS support it natively, Windows requires a paid codec extension, and many web platforms, email clients, and image editors still don't support HEIC. JPG is universally supported.
Does Picmal preserve photo metadata during conversion?
Yes. Picmal preserves all EXIF metadata including date taken, GPS coordinates, camera model, and exposure settings when converting HEIC to JPG. Your organized photo library stays intact.
Is Picmal free to convert HEIC to JPG?
Picmal is free for 7 days, then a one-time purchase of $29: no subscription, no hidden fees. 14-day money-back guarantee after you buy.
How does Picmal compare to using Preview or Automator?
Preview converts one file at a time and doesn't preserve all metadata. Automator workflows are fragile and slow for large batches. Picmal converts hundreds of files with full metadata preservation, quality control, and drag-and-drop simplicity.
Can I convert HEIC to JPG without uploading my photos online?
Yes. Picmal processes everything locally on your Mac. Unlike web-based converters, your photos never leave your device. No upload limits, no file size restrictions, no privacy concerns.
