PNG to HEIC Converter
Convert PNG files (released 1996, Lossless) to HEIC (Lossy (HEVC-based), typically ~50% smaller than equivalent JPEG). Runs in your browser — no upload, no signup.
Based on 12,431+ conversions delivered
The thing most people want to know about converting PNG to HEIC is what happens to quality. Here's the honest version: PNG is Lossless and HEIC is Lossy (HEVC-based), so the move changes how the image is stored — transparency becomes Yes and animation support becomes Yes (image sequences). Output size depends on the resolution and content of your source image. For most everyday conversions the visible difference is negligible and the compatibility or size gain is worth it; the comparison and pitfalls below flag the cases where it isn't, so you can decide with the facts in front of you.

Heads up before converting PNG → HEIC
What changes — and what your conversion will cost — based on how PNG and HEIC differ.
Older clients may not render HEIC
HEIC support: Safari only — convert for Chrome/Firefox/cross-platform. Modern browsers and OS image viewers handle it natively, but legacy email clients, older CMS thumbnailers, and some print/design tools still don't. Confirm the downstream consumers in your pipeline accept HEIC before swapping at scale, or ship a PNG fallback for the long tail.
Chroma subsampling kicks in
PNG stores full-resolution colour channels. HEIC's default lossy mode subsamples chroma (typically 4:2:0) — half the colour information thrown away to save bytes. The effect is invisible on photos but visible on sharp text, fine lines, and saturated edges (chromatic aberration around text, halos on logos). For UI screenshots and graphic content, prefer a target without chroma subsampling (PNG, WebP-lossless, AVIF 4:4:4) instead.
Best practices for PNG → HEIC
Concrete settings to pick before you convert PNG to HEIC.
- Always preview the HEIC output before bulk-downloading — colour shifts, transparency surprises, and quality artifacts show up in the preview before they ship.
- Strip EXIF metadata if file size or privacy matters — camera GPS coordinates, timestamps, and serial numbers travel inside the image bytes by default.
- For photographic content, target a HEIC quality between 80 and 85 — that's the sweet spot where most encoders stop showing visible artifacts and the file size curve flattens.
- Verify the alpha channel rendered as expected — premultiplied vs straight alpha and edge halos around antialiased pixels are the most common surprises when going to HEIC.
- For web HEIC delivery, encode in sRGB — wider colour spaces (Display P3, ProPhoto) render unpredictably across browsers and email clients.
When NOT to convert PNG → HEIC
Honest cases where this conversion is the wrong call — pick a different format or keep your PNG source.
Skip if your audience uses legacy browsers
HEIC doesn't render on every old browser, email client, or built-in OS viewer. If your traffic includes IE11, legacy Outlook, or older Android WebViews, stay on PNG (or a universal format like JPEG/PNG) — or ship HEIC alongside a fallback via the HTML <picture> element.
Skip if the file is bound for print
HEIC is a delivery-grade web format. Print pipelines (offset, large-format, packaging) expect TIFF, PDF, or high-bit-depth PNG with embedded ICC profiles and a CMYK option. Converting PNG to HEIC for a print job will likely fail prepress checks — keep the original or convert to a print-friendly format instead.
