HEIC vs PNG: Which Format Is Better?

Short answer: HEIC is better for photos (dramatically smaller files with excellent quality), and PNG is better for screenshots, graphics, logos, and anything that needs transparency or universal compatibility. They serve different purposes, so "better" depends entirely on what you're doing with the image.

These two formats barely overlap in practice. HEIC is a modern photo format optimized for cameras. PNG is a lossless format built for precision and transparency. Choosing between them is less about quality and more about matching the format to the job.

Quick Comparison

What Is HEIC?

HEIC (High Efficiency Image Container) is Apple's default camera format since iOS 11. It uses HEVC (H.265) compression to store photos at roughly half the file size of older formats with no visible quality loss. A single HEIC file can also hold image sequences (Live Photos), depth maps, and non-destructive edit data.

The format is technically impressive but has a significant limitation: support outside the Apple ecosystem ranges from partial to nonexistent. Windows requires a codec extension. Most browsers besides Safari cannot display HEIC at all. For a deeper look at how the format works and where it came from, see our complete guide to HEIC.

What Is PNG?

PNG (Portable Network Graphics) launched in 1996 as a patent-free replacement for GIF. It uses lossless compression, meaning every pixel is preserved exactly as captured -- no quality loss on save, ever. PNG's signature feature is full alpha transparency, which is why it became the standard for logos, icons, UI elements, and any image that needs to sit on a non-white background.

PNG works everywhere. Every browser, every operating system, every image editor, every social platform. You will never encounter a device that refuses to open a PNG file. That universality is its greatest strength. For the full technical breakdown, read our guide to PNG.

File Size Comparison

This is where the two formats diverge sharply -- but which one "wins" depends on the image type.

Photos (12MP smartphone image):

• HEIC: ~2-3 MB (lossy HEVC compression, optimized for photographic content)
• PNG: ~15-25 MB (lossless, stores every pixel without compression shortcuts)

HEIC files are roughly 80-85% smaller than PNG for the same photograph. This gap is enormous. Storing 1,000 vacation photos as PNG would consume 15-25 GB; as HEIC, 2-3 GB.

Screenshots (1920x1080 desktop capture):

• HEIC: ~150-250 KB
• PNG: ~200-400 KB

The gap narrows with screenshots because PNG's lossless compression handles flat colors, sharp text, and uniform regions efficiently. HEIC still wins, but the difference is modest enough that PNG's universal compatibility tips the balance.

Graphics and logos (simple vector-style image):

• HEIC: ~50-100 KB
• PNG: ~30-80 KB

For simple graphics with few colors and hard edges, PNG can actually match or beat HEIC. Lossless compression excels when the image has large areas of identical color.

The takeaway: HEIC's size advantage is massive for photographs and shrinks as images become simpler and more graphic in nature.

When to Use HEIC

HEIC makes sense when the priority is storage efficiency for photographic content:

• iPhone photography. Your camera already shoots HEIC by default. Keep it that way -- you get twice the storage capacity with no visible quality difference versus JPEG.
• Apple-to-Apple sharing. Sending photos between iPhones, iPads, and Macs? HEIC transfers are smaller and faster with no conversion needed.
• Photo archives. If you're backing up thousands of photos to iCloud or a Mac, HEIC saves significant disk space while preserving 10-bit color depth.
• Live Photos and bursts. HEIC is the only format that bundles image sequences, audio, and depth data into a single file.

HEIC is a specialist -- outstanding at photographs within the Apple ecosystem, limited everywhere else.

When to Use PNG

PNG is the right choice when precision, transparency, or compatibility matters more than file size:

• Web graphics and UI elements. Logos, icons, illustrations, and buttons with transparency need PNG. It is the web standard for non-photographic images.
• Screenshots. PNG preserves text sharpness and UI detail perfectly. No compression artifacts, no blurring around sharp edges.
• Cross-platform sharing. Sending an image to someone and not sure what device they use? PNG opens everywhere, no questions asked.
• Images requiring transparency. Product photos on white backgrounds, overlays, watermarks -- PNG's alpha channel handles partial transparency that JPEG cannot.
• Archival quality. When you need a pixel-perfect copy with zero degradation over repeated saves, PNG's lossless compression guarantees it.
• Print-ready graphics. Designers use PNG for deliverables that need exact color reproduction and crisp edges.

How to Convert Between HEIC and PNG

Need to turn iPhone photos into universally compatible PNGs? Or convert screenshots for use in an Apple-only workflow? Pixotter handles both directions right in your browser -- no upload to a server, no software to install.

To convert HEIC to PNG:

1. Open Pixotter's HEIC to PNG converter.
2. Drop your HEIC files onto the page.
3. Download your PNG files.

The conversion runs entirely client-side via WebAssembly. Your photos never leave your device -- they are processed in your browser's memory and discarded when you close the tab.

One thing to consider: converting a 2 MB HEIC photo to PNG will produce a 15-25 MB file because PNG stores the full uncompressed pixel data. If you need smaller files that still work everywhere, converting HEIC to JPG is often the more practical choice for photographs. For graphics and screenshots where you need transparency, PNG is the correct target.

FAQ

Is HEIC better quality than PNG?

Not inherently. PNG is lossless -- it preserves every pixel exactly. HEIC in its default lossy mode discards some data (imperceptibly for photos, but it is technically lossy). HEIC does support lossless compression, but its real advantage over PNG is file size for photographic content, not absolute quality.

Can I use HEIC images on a website?

Practically, no. Only Safari supports HEIC. Chrome, Firefox, Edge, and other browsers cannot display HEIC files. Use PNG for graphics with transparency, WebP for photographs, or JPEG as a universal fallback.

Why are my iPhone photos in HEIC instead of PNG?

iPhones shoot in HEIC because it produces photos roughly 50% smaller than JPEG (and 80% smaller than PNG) with no visible quality loss. PNG would be impractical for camera output -- a single 12MP photo would be 15-25 MB. You can switch to JPEG in Settings > Camera > Formats > Most Compatible, but there is no option to shoot directly in PNG.

Does HEIC support transparency like PNG?

Yes, HEIC supports alpha transparency. However, this capability is rarely used in practice because HEIC files are primarily camera output (photos do not need transparency). PNG remains the standard for transparent images on the web and in design workflows.

Should I convert all my PNGs to HEIC to save space?

Only if they are photographic images and you exclusively use Apple devices. For screenshots, graphics, logos, and anything you share outside the Apple ecosystem, keep PNG. The compatibility loss is not worth the file size savings for non-photographic content.

Which format is better for sending images over email?

PNG. Email clients universally support PNG, and recipients can open the file on any device. HEIC attachments may appear as unrecognizable files to anyone not on macOS or iOS. If file size is a concern for photo attachments, convert to JPEG instead -- it offers good compression with universal support.

Can Photoshop open both HEIC and PNG files?

Photoshop (version 22.0 and later) supports both formats. Older versions and some specialized image tools cannot open HEIC. PNG has been supported by virtually every image editor since the late 1990s. If you work across multiple tools, PNG is the safer choice for interchange.
