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.

Your file, handled carefully
Uploads are encrypted in transit and at rest, 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 first 50 conversions every month are free on any plan, including PNG to HEIC.
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?
No, not by default. You choose a retention window at upload — immediate, 1 hour, 24 hours or 7 days — and the file is permanently deleted after that.
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, and nothing is charged against your quota for a failed job.
