How PNG to HEIC conversion works
The Portable Network Graphics format uses lossless DEFLATE compression and supports a full alpha-transparency channel, preserving every pixel exactly as encoded. Converting to HEIC produces an image file that applies H.265 (HEVC) intra-frame compression, which usually yields smaller files than JPEG at similar quality, used natively by Apple devices. This conversion changes the file's encoding, compression method, and supported feature set. Colour profiles and orientation metadata are preserved in the output. This makes HEIC the practical choice when the destination system requires it or when the target format offers better compatibility or compression. 1converter runs this conversion on the server: your file is uploaded encrypted over HTTPS, converted using trusted open-source libraries, and the output is held for 24 hours before automatic deletion.
Sources and specifications
Quality levels for PNG → HEIC
| Level | File size | Speed |
|---|---|---|
| Low qualitySmallest file, basic quality | Very small | Very fast |
| Medium qualityRecommendedBalanced size and quality | Medium | Fast |
| High qualityLarger file, great quality | Large | Moderate |
| Maximum qualityLargest file, best possible quality | Very large | Slow |
Image Tip: For photos, Medium quality offers the best balance. For graphics with text or sharp edges, use High or Maximum quality to preserve clarity.
When to convert
What the HEIC file is good for and why people convert to it.
- Smaller HEIC files than PNG by using HEVC/HEIF compression
- Preserves alpha transparency when the PNG uses transparency
- Save app screenshots that were exported as PNG and want lighter storage
- Archive transparent logos in a space-efficient format for mobile apps
Where your file goes
- It travels to our server over an encrypted HTTPS connection and is converted there.
- The HEIC file comes back as a private link. It stops working after 24 hours on Free and 7 days on paid plans, and then the files are deleted.
- Want the file to stay on your device? Private Mode converts images right in the browser. Open Private Mode
