Is HEIC better quality than JPEG?

There is no universal answer. Quality depends on how each file was encoded. HEIC is designed for efficient modern photo storage, while JPEG is chosen more often for compatibility.

Is HEIC smaller than JPEG?

It can be, but there is no fixed ratio. Source images and encoding settings matter.

Should I convert all HEIC photos to JPEG?

No. Convert when you need JPEG compatibility and keep the HEIC originals if they matter to you.

Are JPG and JPEG different?

No. They are the same image format with different filename extensions.

HEIC vs JPEG: Quality, File Size, Compatibility

HEIC vs JPEG: the short answer

HEIC is a good original photo format when your devices and apps support it. JPEG is the safer choice for websites, older software, printing services, and sharing with unknown recipients.

JPG and JPEG are the same format

JPG and JPEG refer to the same image format. The difference is only the filename extension, so this HEIC vs JPEG comparison also applies when you see .jpg.

For the terminology, see HEIC vs HEIF.

HEIC vs JPEG at a glance

The biggest everyday difference is efficient storage versus broad compatibility.

Question	HEIC	JPG / JPEG
Typical use	Modern phone photos and efficient source storage.	Sharing, websites, printing, editing, and broad compatibility.
Compression	Commonly uses modern HEVC-based image compression.	Uses JPEG lossy compression.
Compatibility	Good on many newer devices but uneven in some apps and websites.	Very widely supported across old and new software.
Metadata	Can carry photo metadata and richer HEIF structures.	Can carry common metadata such as EXIF, depending on the file and the software that handles it.
Best practical choice	Keep the original when your apps support HEIC.	Create a JPEG copy when the destination needs maximum compatibility.

File size and image quality

HEIC often aims to store photos efficiently, but there is no single file-size ratio that applies to every HEIC and JPEG. The result depends on the source image and the quality settings used for each format.

If quality matters, compare the converted JPEG with the original before deleting anything.

Compatibility is where JPEG usually wins

JPEG works almost everywhere: browsers, office software, printers, upload forms, social tools, and older image editors. HEIC support is improving, but it is still more likely to cause a compatibility problem.

That is why many people keep HEIC as the original and create JPEG copies only when needed.
