What this tool does

Source pixels (or vector paths) are rasterized as required, then encoded to AVIF.

ICC profiles may be copied, transformed, or stripped depending on encoder defaults.

  • HEIC family — HEIF: HEVC still frames; auxiliary depth or thumb tracks possible.
  • AVIF family — AVIF output: HEIF wrapper around AV1 intra frames.
  • Encode traits — Raster exports fix dimensions, subsampling, and ICC embedding per encoder—vectors rasterize to one pixel grid.

How to convert HEIC to AVIF?

  1. Choose file — upload a HEIC file that matches this page (allowed extensions apply).
  2. Convert to AVIF — lock the target format if needed, then start the job and wait for status updates.
  3. Download — grab the finished file from your job link before the retention window ends.

Why convert HEIC to AVIF?

Each hop trades smaller files against visible defects; switching formats can trade alpha, animation, or HDR side data against simpler decode surfaces.

HEIC minimizes phone storage; AVIF trades that ecosystem for decoder breadth on PCs—expect different gamma handling versus Apple preview.

Vectors versus rasters trade infinite zoom against predictable pixel weight—prefer AVIF when bitmap semantics matter more than editable paths.

Common reasons to convert HEIC to AVIF

  • Point Imgix URLs at AVIF when CDNs rewrite HEIC masters already in S3 buckets.
  • Emit AVIF from GitLab CI before Slack when reviewers diff HEIC screenshots.
  • Serve AVIF from next/image when builds optimize assets but archives stay HEIC.
  • Stage AVIF on Marketing Cloud when ZIP packs must match hosted filenames.
  • Sync AVIF into DSM when Sketch stayed HEIC but the style guide expects AVIF.

Will converting HEIC to AVIF affect quality or file size?

Pixels decoded from the source usually remain visible after conversion.

Another lossy step softens edges; JPEG detail lost earlier never returns—size exports to the screen or print size you need.

HEIC vs AVIF

HEIC (HEIC)

HEIC is Apple’s efficient photo bundle on many iPhones. Windows or Android recipients may need a converter before they can open it. JPEG or PNG is still the safest attachment when you cannot control the reader’s software.

AVIF (AVIF)

AVIF uses modern compression related to AV1 and can shrink photos sharply where decoders exist. Social sites and older viewers sometimes reject it, which pushes creators back to JPEG or PNG for guaranteed opens.

HEIC to AVIF changes which apps open first—Chrome, Photoshop, and Outlook each bind double-click actions to the new extension.

Troubleshooting

  • Lossy recompression: blocking, ringing, and banding show first on text, edges, and skies—inspect at 100% zoom.
  • Alpha: formats without an alpha channel (JPEG, most HEIC stills) cannot produce real transparency in the output unless you supply it elsewhere.
  • Dimensions and DPI: raster outputs fixed pixel grids—upscaling later softens detail; embedded ICC profiles may shift colors across viewers.
  • Decode support: older viewers may lack AVIF decoders (AVIF, WebP); verify the destination stack.
  • Upload fails or stalls: refresh the page, try a different browser, or disable strict content blockers for this session.

HEIC to AVIF FAQ

Most still images finish quickly, but huge TIFF masters or multi-megapixel raw exports can queue longer. HEIC and AVIF decoding also adds work compared with small JPEGs.

Yes. Upload a file, confirm the output format, run the job, and download the result from the status page.

Use the From/To menus on this converter or open another slug page if the pair you need is supported. Unsupported combinations will not appear as selectable options.

PNG, WebP (depending on mode), GIF, and SVG workflows handle alpha differently than JPEG. If your HEIC artwork relied on transparency, pick AVIF accordingly or expect a flat background. Preview edges after conversion.

AVIF opens in virtually every image viewer when AVIF is JPEG or PNG. AVIF and WebP need newer browsers or apps. If the recipient runs older software, choose a more conservative format after checking their environment.
