The scorecard that matters

HEIC wins on engineering. JPG wins on reach. Neither fact is controversial — the question is which one serves the file in front of you.

Compatibility: who opens what

Platform / app	HEIC	JPG
iPhone / iPad / macOS	✅ Native everywhere	✅ Native
Safari	✅ Renders it	✅
Chrome / Edge / Firefox	❌ No decode	✅
Windows 10/11	⚠️ Needs free “HEIF Image Extensions” codec; HEVC video plugin for some files	✅
Android 10+	✅ Most devices	✅
Android < 10	❌ Rare	✅
Google Photos / iCloud web	✅ Server-side support	✅
Upload forms / CMS / forums	⚠️ Frequently rejected	✅ Universally accepted
Messaging & email	⚠️ iOS auto-converts; other apps vary	✅

File size and quality

At equivalent visual quality HEIC runs roughly 40–55% smaller — a 4 MB JPEG is a ~2 MB HEIC. It also stores things JPEG can’t: 10-bit color, transparency, image sequences (bursts, Live Photos) and depth maps. JPEG’s counter-argument isn’t technical: it’s that a JPEG opens literally everywhere, instantly, with zero codecs to install and zero questions asked.

So when should you convert?

Convert to JPG when the file is leaving your hands — sharing with Windows/Android users, uploading to forms, printing services, embedding in documents, or archiving for the long term. JPG at 90% quality is visually identical for photos and universally readable.

Keep HEIC when the file stays inside the Apple ecosystem — your own library, AirDrop between Apple devices, iCloud. You keep the smaller size, HDR and Live Photo extras.

Convert to PNG when you need a lossless, metadata-free copy — editing source material, screenshots, or anything you’ll re-save repeatedly (PNG has no generation loss).

Convert to WebP when the destination is a website — modern browsers all decode it, and files run smaller than JPG at the same quality.

The boring, correct default

Shoot in HEIC, convert on export. Your iPhone already does this automatically for shares and transfers (the Automatic setting in Photos → Transfer to Mac or PC); for the cases it doesn’t cover — drag-and-drop, web uploads, direct file copies — the converter does the same job locally. And if the double-handling annoys you, switching the camera to Most Compatible makes the phone shoot JPG natively — just know you’re paying ~2× storage for the convenience.

Frequently asked questions

Is HEIC higher quality than JPG?

Per byte, yes — HEVC preserves more detail and gradient smoothness at the same size, and supports 10-bit color. Per photo it doesn't matter much: a HEIC converted to 90% JPG is visually identical on any screen. The real difference is compatibility, not image quality.

Does converting HEIC to JPG remove metadata?

On this site, yes — conversion runs through a canvas, so EXIF, GPS and thumbnails are stripped by construction. Other converters may copy metadata over; check before assuming.

Will HEIC ever replace JPG?

Unlikely to fully replace it — JPEG's 30-year head start means every device and protocol on earth reads it. HEIF derivatives keep growing inside ecosystems (iPhone photos, some Samsung cameras, AVIF on the web), but JPG remains the lingua franca for sharing.

What about AVIF?

AVIF is HEIF's open, royalty-free cousin — same container family, AV1 codec instead of HEVC. Browsers actually support it (Chrome, Firefox, Safari 16+), so for web publishing it's the more future-proof 'modern format'. HEIC remains the iPhone-camera format.
