AVIF to HEIC Converter
Convert AVIF files (released 2019 (AOMedia), Lossless + Lossy (AV1-based)) 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
Every AVIF to HEIC conversion here runs inside your browser — your files are read, converted, and handed back without ever being uploaded to a server. That matters when the images are personal photos, client work, or anything you'd rather not hand to a cloud service. AVIF is Lossless + Lossy (AV1-based) and suits Bandwidth-critical pages with modern audiences; HEIC is Lossy (HEVC-based) and fits iPhone photos, Apple ecosystem storage and sharing better. Output size depends on the resolution and content of your source image. Drop one file or a whole batch — the conversion is identical either way and nothing leaves your device. Below you'll find how the two formats compare and the details worth checking before you convert at scale.

Heads up before converting AVIF → HEIC
What changes — and what your conversion will cost — based on how AVIF and HEIC differ.
Animation collapses to a single frame
AVIF can hold multiple frames in one file; HEIC cannot. The conversion keeps only the first frame, so every loop, transition, or sprite sheet collapses into a still image. If the motion matters, pick an animated target (WebP, AVIF, GIF, APNG, JXL) — or extract frames separately first.
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 AVIF fallback for the long tail.
Best practices for AVIF → HEIC
Concrete settings to pick before you convert AVIF 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 AVIF → HEIC
Honest cases where this conversion is the wrong call — pick a different format or keep your AVIF 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 AVIF (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 AVIF to HEIC for a print job will likely fail prepress checks — keep the original or convert to a print-friendly format instead.
