If you’ve ever tried to upload iPhone photos to a website and hit a weird file type like .HEIC, you’re not alone. HEIC is common on modern iPhones, but plenty of sites, apps, and older devices still prefer JPG. So which one should you use in 2026?

The honest answer depends on your goal. If you want smaller files with excellent quality, HEIC is hard to beat. If you want maximum compatibility, JPG still wins. This guide breaks down the differences in plain English so you can choose the right format for sharing, storing, editing, and uploading.

If you need to convert quickly, use iConvertOnline HEIC to JPG to turn HEIC files into standard JPGs in seconds, ready for almost any platform.

What is HEIC?

HEIC (High Efficiency Image Container) is the default photo format on iPhone for many users. It’s designed to keep file sizes smaller while preserving strong image detail. HEIC can also store extra information like edits and metadata, which is part of why it works so smoothly inside Apple’s ecosystem.

What is JPG?

JPG (or JPEG) is one of the most widely supported image formats in the world. It works on almost every device, browser, app, website, and upload form. If your goal is “make sure this opens everywhere”, JPG is the safe choice.

The trade-off is efficiency. JPG is often larger than an equivalent HEIC photo at similar perceived quality, and it uses lossy compression, which can reduce quality over multiple edits and re-saves.

HEIC vs JPG in 2026: the real differences

Both formats can look great, but they behave differently depending on how you use them.

1) File size

HEIC is usually smaller. If you take a lot of photos and want to save storage space or back up faster, HEIC often gives you similar quality at a lower file size.

JPG is usually larger at the same visual quality, especially for modern phone photos with lots of detail and sharp edges.

2) Compatibility

JPG wins on compatibility. It’s accepted across nearly all websites, apps, client portals, marketplace listings, and online forms.

HEIC support is improving, but it’s still inconsistent across some platforms and older software. If something says “invalid file type”, it’s often because you uploaded HEIC.

3) Quality and compression

At similar file sizes, HEIC often preserves detail better than JPG. JPG can show compression artefacts sooner, especially around edges, gradients, and fine textures.

That said, a high-quality JPG export can still look excellent for everyday sharing and online uploads.

Inside Apple’s world, HEIC is convenient because edits and metadata are handled smoothly. Outside Apple, JPG remains the simplest option for editing across tools and sending to other people without file-type issues.

5) Transparency and design use

Neither HEIC nor JPG is ideal for transparency. If you need a transparent background (logos, overlays, cut-outs), convert to PNG instead. You can do that with HEIC to PNG or JPG to PNG.

When you should use HEIC

You’re mainly in the Apple ecosystem: iPhone, iPad, Mac, AirDrop, iCloud sharing.
You want smaller file sizes: Better storage efficiency and faster backups.
You take lots of photos: HEIC reduces overall storage usage over time.
You’re not uploading to strict platforms: When the receiving side supports HEIC properly.

When you should use JPG

You need maximum compatibility: Websites, client uploads, portals, marketplace listings, online forms.
You’re sending photos to mixed devices: JPG avoids the “can’t open this file” problem.
You’re posting online: CMS uploads, social platforms, profile images, product listings.
You want fewer workflow issues: JPG is the default “safe format” almost everywhere.

FAQs

At similar file sizes, HEIC often preserves detail better than JPG. JPG can still look excellent, but it may show compression artefacts sooner, especially after repeated edits and re-saves.

Many upload forms only accept common formats like JPG and PNG. If HEIC is not on their accepted list, the upload will fail.

If you’re sending to someone who may not be using Apple devices, or you’re uploading to a portal, converting to JPG is the safest option.

Any conversion to a lossy format can reduce quality slightly, but for most everyday photos the difference is minimal. The main benefit is that JPG works almost everywhere.
