PNG to HEIC converter
Convert PNG files to HEIC with TLS uploads and automatic deletion. Apple's default photo format — efficient but poorly supported outside the Apple ecosystem.
PNG → HEIC is queued for rollout
Image, spreadsheet, document and media conversions are live today. This pair needs our office engine, which is next on the roadmap.

Why convert PNG to HEIC?
HEIC uses lossy compression, so expect a noticeably smaller file than the lossless PNG original, at some cost to quality. The main reason to convert PNG to HEIC is compatibility: HEIC opens in every browser, image viewer and design tool without a plugin, while PNG doesn't always. If you're sharing a file with someone else, sending it to a tool that expects a specific format, or archiving it for the long term, HEIC is usually the safer target.
Format comparison

| MIME type | image/png | image/heic |
| Compression | lossless compression | lossy compression |
| Category | image | image |
Common reasons to convert PNG to HEIC
- Uploading to a website builder, ad network or CMS that only accepts HEIC
- Shrinking page load time with a more compressible file than the PNG original
- Cutting file size for storage or bandwidth, where some quality loss is an acceptable trade-off
Your file, handled carefully
Uploads use TLS in transit and AES-256 SSE-S3 at rest in production (when the production S3 credential gate is enabled), are processed in an isolated job, and deleted on the schedule you choose — as fast as immediately. We don't index, search, or share files between accounts. Read the full security model →
Frequently asked questions
Is converting PNG to HEIC free?
Yes — the Free plan includes 50 conversions every month, including PNG to HEIC. Paid plans raise that limit.
Will I lose quality converting PNG to HEIC?
HEIC is apple's default photo format — efficient but poorly supported outside the apple ecosystem. We use the highest-quality encoder settings by default so visual or data loss is minimized.
Do you keep a copy of my file?
Files are deleted automatically based on your plan's retention options. Free accounts can keep results for 1h or 24h; Pro and above add options such as delete-immediately and 7 days.
What is PNG?
Lossless raster format with alpha transparency, ideal for graphics and screenshots.
Will my converted file have a watermark?
On the Free plan, HEIC output includes a small "Converted with Convyx" mark. Pro ($9/mo) removes it, along with the 25 MB file size cap.
What happens if a conversion fails?
You get a clear error message and the job is marked failed in your history — we never silently drop a file. Retry is one click. Monthly quotas count attempts (including failures) because processing starts as soon as the job is created.
