HEIC vs JPG vs PNG: Which Image Format Should You Use?

If you’ve ever wondered why the same photo can be a HEIC, a JPG, or a PNG — and which one you actually want — here’s a plain-language guide. Each format has a job it’s good at, and picking the right one saves you headaches with file size, quality, and compatibility.

The short answer

• JPG — best for photographs and sharing. Small files, opens everywhere.
• PNG — best for graphics, screenshots, transparency, and lossless quality.
• HEIC — Apple’s space-saving format for iPhone photos. Great on Apple devices, awkward everywhere else.

If you just want something that works everywhere, JPG is the safe default. Read on for when each one wins.

JPG (JPEG)

JPG is the most widely supported image format in the world. It’s been around since the early 1990s and opens on essentially every device and app ever made.

Best for: photographs, sharing online, emailing, anywhere file size matters. Trade-off: JPG uses “lossy” compression, meaning it discards some data to shrink the file. For photos this is invisible; for sharp text or graphics it can look slightly fuzzy.

PNG

PNG is “lossless” — it preserves every pixel exactly. It also supports transparency, which JPG can’t do.

Best for: screenshots, logos, graphics with text, images with transparent backgrounds, anything where crisp edges matter. Trade-off: files are larger than JPG, especially for photographs.

HEIC

HEIC is Apple’s default photo format since 2017. It packs JPG-level quality into roughly half the file size — excellent for storage on your phone.

Best for: saving space on Apple devices. Trade-off: limited support outside Apple. Many Windows programs, websites, and older apps can’t open it, so you’ll often need to convert it before sharing.

Quick decision guide

• Sharing a photo with anyone, anywhere? → JPG
• Screenshot, logo, or need transparency? → PNG
• Stuck with a HEIC from an iPhone? → convert to JPG (or PNG for max quality)
• Website saved an image as WebP? → that’s a separate Google format; convert it to JPG or PNG too

Frequently asked questions

Is PNG better quality than JPG? PNG is lossless so it’s technically higher fidelity, but for photographs the difference is usually invisible — and PNG files are much larger. Use PNG for graphics, JPG for photos.

Why does my iPhone use HEIC instead of JPG? To save storage space. You can switch to JPG in Settings → Camera → Formats → Most Compatible.

Which format is smallest? HEIC is smallest, then JPG, then PNG — but smallest isn’t always best if compatibility matters.
