How PNG to HEIF 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 HEIF produces a document file that stores data in the HEIF format. This embeds the raster image inside a document container, fixing its dimensions on the page. Metadata such as creation date is preserved where the target format supports it; features the target format cannot represent are dropped. This makes HEIF the practical choice when the destination system requires it or when the original format is not supported by the target application. 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.

Frequently Asked Questions

Everything you need to know about converting PNG to HEIF

Not always—PNG is lossless, while HEIF is typically compressed lossy. If the tool supports near-lossless/high quality, you can minimize differences, but the bytes may not be identical.
HEIF can store an alpha channel, so transparency may be preserved. If the source PNG uses full transparency or partial alpha, verify the output because some viewers handle HEIF alpha differently.
PNG uses lossless DEFLATE and is often large for photographic content. HEIF uses modern image compression (often including inter-frame/advanced intra methods), which can greatly reduce size for similar perceived quality.
HEIF is supported on many modern platforms, but not every editor or browser handles it the same way as PNG. For maximum compatibility, you may need to test on your target devices or export again when required.
