HEIC vs JPEG vs PNG vs WebP — Full Format Comparison

Pick the wrong image format and you’ll either bloat your storage, lose quality, or end up with a file nobody can open. HEIC, JPEG, PNG, and WebP each shine in different situations. Here’s a clear, side-by-side comparison so you always know which one to reach for.

The quick answer

• HEIC — best for storing photos on your iPhone (smallest size, great quality), worst for compatibility.
• JPEG (JPG) — best for sharing photos anywhere; works on everything, but less efficient than modern formats.
• PNG — best for graphics, screenshots, logos, and anything needing transparency or perfect detail; large files.
• WebP — best for websites; small files with transparency support, but not ideal for sharing with people.

Side-by-side comparison

File size: HEIC and WebP win

If you care about saving space, HEIC and WebP are the clear leaders. Both use modern compression and can be 25–50% smaller than a JPEG at the same visual quality. Apple’s own figures put HEIC at roughly half the size of an equivalent JPEG.

PNG sits at the opposite end. Because it’s lossless — it throws away no data — PNG files are the largest of the group, often several times bigger than a JPEG of the same photo. That’s the price of perfect quality.

Quality: it depends on what you’re saving

For photographs, lossy formats (HEIC, JPEG, WebP) look excellent and are the right choice — the eye can’t see the discarded data. HEIC and WebP edge out JPEG because they retain more detail per kilobyte.

For graphics with sharp edges — text, logos, screenshots, line art — lossless PNG is the winner. JPEG introduces fuzzy “artifacts” around hard edges, while PNG keeps them crisp. If your iPhone photo needs to become a flawless, editable master copy, converting HEIC to PNG preserves every pixel.

Transparency: everyone but JPEG

Need a transparent background — for a logo or a product image? PNG, WebP, and HEIC all support an alpha channel. JPEG does not, and will fill any transparent area with a solid color. This is the single most common reason designers avoid JPEG. (We go deeper in does HEIC support transparency.)

Compatibility: JPEG is king

Here’s where the modern formats stumble. HEIC only displays natively in Apple’s ecosystem and Safari. WebP is now supported in all modern browsers but is awkward to share with people — email it to someone and they may not be able to open it easily. PNG and especially JPEG work absolutely everywhere: every phone, every PC, every printer, every app.

This is why the practical workflow for iPhone users is so consistent: shoot in HEIC to save space, then convert to JPG the moment you need to share, upload, or print.

So which should you use?

• Storing iPhone photos? Keep them as HEIC.
• Sharing a photo with anyone? Convert it to JPG with the HEIC to JPG converter.
• Need transparency or perfect detail? Use PNG.
• Optimizing images for your own website? Use WebP.

There’s no single “best” format — there’s a best format for each job. Match the format to the task and you’ll get the smallest file, the right quality, and a photo that opens wherever it needs to. When you’re ready to convert, our HEIC to JPG converter handles it in your browser with nothing uploaded. New to all this? Start with what is a HEIC file.
