HEIC (High Efficiency Image Container) is Apple's implementation of the HEIF (High Efficiency Image File Format) standard, developed by MPEG. It uses H.265 (HEVC) compression — the same algorithm used in 4K video — to encode still images. The result is a file that is approximately 50% smaller than an equivalent JPEG at the same visual quality. Apple switched to HEIC in iOS 11 to let the iPhone store more photos in the same storage space.

Frequently Asked Questions
Everything you need to know about this conversion tool.
Apple introduced HEIC in iOS 11 as the default camera format. It uses up to 50% less space than JPG for the same quality, saving storage on your device.
Windows 10/11 can open HEIC files only after installing the free HEVC Video Extensions from the Microsoft Store. Converting to JPG is far easier for broad compatibility.
Yes. HEIC is Apple's specific flavour of HEIF. We accept both .heic and .heif file extensions interchangeably.
Converting to JPG at quality 90+ is visually lossless. Converting to PNG is always lossless. The original HEIC file is not modified.
Yes. EXIF orientation data is read and applied before conversion so your photos appear correctly rotated in the output file.
Connect via USB and use Windows Explorer or Finder, use AirDrop to Mac, or download from iCloud.com. You can also configure iPhone to transfer as JPG automatically in Settings > Photos > Transfer to Mac or PC.

Who Uses This Tool
Real-world use cases from professionals across different industries.
Windows User
Open iPhone Photos on Windows
Airdrop or cable-transfer your iPhone photos and instantly convert HEIC to JPG so they open in Windows Photos without codec issues.
Email Sender
Share Photos via Email
HEIC attachments may not display in non-Apple email clients. Convert to JPG first to guarantee recipients on Gmail, Outlook, or Android see your photo.
Content Creator
Upload to CMS Without Issues
WordPress, Squarespace, and most CMSes reject HEIC uploads. Convert to JPG or WebP before uploading for seamless media library ingestion.
Freelance Photographer
Deliver Client-Ready Files
When shooting with iPhone 7+, deliver universally compatible JPG or PNG files to clients who may not have Apple software.
Designer
Import Into Editing Software
Convert HEIC to PNG or TIFF before importing into Photoshop CC 2017 or earlier, GIMP, Affinity Photo (pre-2.0), or Canva.
Social Media Manager
Post iPhone Photos Anywhere
Twitter, Pinterest, and older social platforms still do not accept HEIC. Convert to JPG for one-click uploads with no format errors.

HEIC Explained: Why Your iPhone Uses It and How to Convert
Since iOS 11 and iPhone 7, Apple uses HEIC as the default camera format. While it saves significant storage space, it creates compatibility headaches when sharing photos with non-Apple users. Here is a complete guide.
What Is HEIC and Why Did Apple Choose It?
Why HEIC Causes Compatibility Problems
Despite being a widely-adopted standard on paper, HEIC requires licensed HEVC decoding hardware or software. Windows 10 and 11 can open HEIC files only after installing the paid (or free via OEM) HEVC Video Extensions codec from the Microsoft Store. Linux has limited native support. Many web apps, CMS platforms, email clients, and older design tools simply do not support HEIC at all, causing blank thumbnails or upload failures.
HEIC vs JPG: Quality and Size Trade-offs
HEIC typically produces files 40–50% smaller than JPEG at equivalent perceived quality. A 12 MP iPhone photo might be 2 MB as HEIC but 4 MB as JPEG. HEIC also natively supports HDR, wide colour (Display P3), 16-bit depth, and burst sequences in a single file. When converting to JPEG at quality 90+, the visual difference is imperceptible to most viewers.
How to Stop Your iPhone Saving as HEIC
Go to Settings → Camera → Formats and select Most Compatible. Your iPhone will then capture photos as JPEG instead of HEIC. Note this uses more storage. Alternatively, go to Settings → Photos → Transfer to Mac or PC and select Automatic — the phone will convert to JPEG when transferring via USB, while keeping HEIC originals on-device.
Preserving Metadata When Converting HEIC
HEIC files store rich EXIF metadata: GPS coordinates, camera model, lens info, shutter speed, ISO, focal length, capture timestamp, and orientation. Our converter preserves all of this in the JPG or PNG output using libheif's built-in metadata extraction. If you are building a photo management workflow, retaining EXIF is critical for correct date sorting and location mapping.
