PNG to HEIC Converter

How to Convert PNG to HEIC Online

1. Upload Your PNG Files: Drag and drop or click "Add Files" to select PNGs from your computer. Batch upload is supported — drop in a folder of icons, screenshots, or design exports at once.
2. Pick a Quality Preset: Default is Very High (Recommended). Step down to High, Medium, Low, or Lowest for progressively smaller files, or switch to "Specific file size" and target an exact KB/MB cap or a percentage of the original.
3. Resize the Output (Optional): Keep the original resolution, scale by percentage, choose a preset (1080P, 1440P, 2160P, etc.), or set custom Width × Height in pixels. Width-only and Height-only options preserve aspect ratio automatically.
4. Convert and Download: Click Convert. Files process on our servers — download individually or as a ZIP. No sign-up, no watermark, no account needed.

Why Convert PNG to HEIC?

PNG is a lossless format built for crisp graphics, screenshots, and transparent logos — but the per-file size is huge. A 4K screenshot can easily run 8-15 MB as PNG. HEIC (High Efficiency Image Container) uses HEVC compression inside the ISOBMFF container, and at "Very High" quality it typically produces files ~50% smaller than the source PNG for photographic content and 30-60% smaller for graphics. Common reasons to convert PNG to HEIC:

• iPhone and iPad import — HEIC is Apple's default photo format since iOS 11 (2017). Bringing PNGs into Apple Photos as HEIC keeps the library format-consistent and uses less of your iCloud quota.
• iCloud storage savings — The free iCloud tier is 5 GB. Converting a few hundred PNG screenshots from 5 MB to 2 MB each can buy back gigabytes without deleting anything.
• Design hand-offs to Apple-only teams — Photoshop, Figma, and Sketch all export PNG by default. If the downstream workflow is iPad / Mac / iPhone, HEIC drops file size dramatically for the same visual fidelity.
• Keep alpha transparency — Unlike JPG, HEIC stores transparency as an auxiliary alpha plane inside the ISOBMFF container, so transparent PNG logos and UI assets convert without losing the cutout.
• Photo archives — If you're consolidating mixed PNG/JPG/HEIC libraries into a single Apple-native format for long-term storage, batch-converting the PNGs is the missing piece.
• App and tvOS assets — Apple's developer tooling accepts HEIC for app artwork. Converting designer PNGs upfront keeps the.ipa size leaner.

HEIC Compatibility Cheat Sheet

For broad web compatibility, convert HEIC to JPG or HEIC to PNG instead — HEIC is best kept inside the Apple ecosystem.

Frequently Asked Questions

Will the alpha transparency in my PNG survive the conversion?

Yes. HEIC stores transparency as a separate auxiliary alpha plane inside the same file, so PNGs with transparent backgrounds — logos, icons, cutout product shots — keep their cutout. Apple Photos, Preview, and Finder all render the transparency correctly. The one caveat is older HEIC viewers that ignore the alpha plane and show the underlying RGB; if your recipient runs an older viewer the alpha may render as opaque black or white.

Why would I ever convert lossless PNG to lossy HEIC?

Because PNG is dramatically larger than necessary for photographic content, and HEIC at Very High preset is visually indistinguishable from the source. The tradeoff is one-way (you can't recover the discarded data), so keep your PNG masters for editing and ship HEIC for distribution, archiving, or Apple Photos library import.

Can Windows and Android users open HEIC files I send them?

Windows 10 and 11 can open HEIC after installing the free HEIF Image Extensions from the Microsoft Store (HEVC Video Extensions is also needed for some uses). Android 10 and later display HEIC natively. Older Windows 7/8 and Android 9-and-earlier need third-party viewers. If you're not sure what your recipient has, convert to JPG instead — JPG is universal.

How do I import the converted HEIC into Apple Photos?

On Mac: drag the.heic files into the Photos app, or use File → Import. On iPhone/iPad: AirDrop them from a Mac, or save them via Files → Photos. Apple Photos stores HEIC natively without re-encoding, so the file you upload is the file that goes into iCloud Photo Library — no quality loss on import.

Does my PNG's resolution and bit depth carry over?

Resolution carries over exactly if you choose "Keep original" in the Image resolution section. Bit depth is converted to HEIC's standard 8-bit per channel by default; HEIC supports up to 16-bit but most viewers (including Apple Photos) display 8-bit. If your PNG is 16-bit (e.g., medical or scientific imagery), HEIC may not be the right target — keep PNG or use TIFF instead.

Will Apple Photos automatically convert HEIC back to JPG when I share?

Yes, if you share via AirDrop, Messages, or email and the receiving device doesn't support HEIC, Apple auto-converts to JPEG per Apple's documentation. iCloud Photos preserves the original HEIC. So your converted PNGs land in the library as HEIC but get shared in compatible formats when needed — best of both worlds.

Should I use "Quality preset" or "Specific file size"?

Use a quality preset when you want a one-click result and don't care about exact file size — Very High is the right default. Use Specific file size when you have a hard cap to hit (e.g., a 500 KB upload limit, a 2 MB messaging app cap). The tool auto-scales quality across batch uploads to land under your target.

Is HEIC lossless like PNG? Can I get a perfectly lossless conversion?

HEIC supports a lossless mode in the HEVC spec, but XConvert's PNG to HEIC path uses lossy compression — that's where the size savings come from. If you need lossless storage with transparency, stick with PNG or use PNG to WebP with lossless mode enabled. HEIC's strength is "visually lossless at a fraction of the size", not bit-perfect preservation.

What about animated PNG (APNG) files — do they convert?

XConvert flattens APNG to a single still HEIC frame (the first frame). HEIC does support image sequences technically, but the tooling and viewer support for animated HEIC is thin compared to GIF or WebP. For animated PNG output, convert PNG to GIF instead and keep the animation intact.
