Choose a HEIC file
Drop a HEIC or HEIF photo into the converter, or open the built-in demo. Decoding is local.
Lossless output from iPhone photos
Convert HEIC to PNG online for lossless pixels and transparency support. This HEIC to PNG converter decodes the photo locally in your browser — no upload, no app.

Real converted output
These examples show the same 1200 × 800 source before and after conversion. Captions state the real file sizes produced locally with the settings described.



Three quick steps
The converter keeps the common path visible and previews the real result before you download. No upload, no queue, no account.
Drop a HEIC or HEIF photo into the converter, or open the built-in demo. Decoding is local.
PNG output is lossless, so no quality slider is used. The converter keeps the decoded pixels and any alpha channel.
Verify the preview and download a separate PNG file. The original HEIC remains unchanged.
Format comparison
Understanding the tradeoff prevents surprises. This table shows what the conversion changes and what stays the same.
| Feature | HEIC | After conversion to PNG |
|---|---|---|
| Compression | Lossy (HEVC) | Lossless |
| Transparency | Yes | Yes |
| Typical file size | Compact | Largest |
| Best for | iPhone and Apple photos | Graphics, logos, sharp text |
| Format | Compression | Transparency | Best starting use |
|---|---|---|---|
| JPG | Lossy with quality control | No | Photos, compatibility, small files |
| PNG | Lossless | Yes | Graphics, logos, sharp text, edits |
| WebP | Lossy or lossless | Yes | Compact modern web images |
Honest answer
PNG is lossless and supports transparency, which matters for graphics and repeated edits. You convert HEIC to PNG when pixel-exact output or an alpha channel is more important than a small file.
A photographic HEIC becomes a much larger PNG because PNG stores every pixel losslessly. For photos where size matters, HEIC to JPG or HEIC to WebP is usually a better choice.
Practical jobs
These are the common situations where the conversion actually saves time, bandwidth, or compatibility headaches.
A PNG master re-encodes without adding artifacts. Convert HEIC to PNG when you will edit or composite the image.
Editors and layout tools open PNG reliably. Convert HEIC to PNG for pixel-exact placement.
Screenshots and UI shots from an iPhone become clean PNG assets that keep sharp text.
PNG is stable and widely supported. Convert HEIC to PNG when you need a dependable lossless copy.
Know the limits
The HEIC-to-PNG converter works on the pixels you provide; it does not repair damaged sources, upscale small files, or add detail. Re-encoding to a lossy format removes information, and converting the same file repeatedly never makes it cleaner.
Browser encoders vary slightly, and very large images can strain memory on older phones. Keep your original, inspect text and edges in the preview, and never rely on a format conversion to hide or redact private content.

Researched questions
Direct answers about cost, privacy, file size, quality, transparency, mobile use, and when to keep the original format.
Yes. The converter is free with no account, subscription, watermark, or daily limit, and it runs entirely in your browser.
No additional quality is lost. PNG is lossless, so the decoded pixels from the HEIC are preserved exactly.
HEIC uses modern lossy compression while PNG stores every pixel losslessly. A larger PNG is expected and is the price of lossless output.
Yes, when the source HEIC contains an alpha channel. PNG supports transparency, so the decoded alpha is preserved.
Yes. Open this page in a browser on the Mac, choose the HEIC file, and download the PNG. Processing is local.
No. The converter uses a WebAssembly HEIF decoder in the browser. Nothing is installed.
The WebAssembly decoder loads once on the first use. After that, additional files convert quickly.
No. The HEIC is decoded and re-encoded inside this browser tab. There is no upload endpoint.
This converter handles one file at a time. Once the decoder is loaded, converting a small batch back to back is fast.
HEIC files up to 100 MB are accepted. Very large photos may use significant memory while decoding.
Use JPG or WebP for photos that need a smaller file. Use PNG when you need lossless pixels, transparency, or an edit master.
