Frequently Asked Questions
Why convert HEIC to AVIF?
HEIC (High Efficiency Image Container) uses lossy or lossless encoding and is best for Apple device photos — iPhone and Mac default format with excellent compression efficiency. AVIF (AV1 Image File Format) uses lossy or lossless encoding and excels at next-gen web images — royalty-free format with better compression than WebP and JPEG. Converting between them lets you take advantage of each format's strengths — for example, using a compressed format for sharing and a lossless format for editing. All conversion happens locally in your browser with no file size limits.
Why would I convert HEIC to AVIF instead of JPG?
AVIF typically produces files 30-50% smaller than JPG at the same visual quality. If you are optimizing for web performance, AVIF gives you faster page loads without sacrificing image clarity.
Will browsers display my converted AVIF image?
AVIF is supported in Chrome 85+, Firefox 93+, and Safari 16.4+. Older browsers like Internet Explorer will not display it. Check your audience's browser support before using AVIF on production sites.
Does the conversion lose quality compared to the original HEIC?
HEIC and AVIF both use modern compression, so the conversion introduces minimal quality loss. For most photos the difference is imperceptible. Choose lossless mode if you need pixel-perfect results.
Can I batch convert multiple HEIC photos to AVIF?
This tool converts one image at a time. Upload and convert each HEIC file individually — there is no limit on the number of conversions you can run.
What color space does the AVIF output use?
The converter preserves the color profile from your HEIC source. If the original uses Display P3 or sRGB, the AVIF output maintains the same color space.

AVIF to HEIC output is not produced here — AVIF input decodes, but Canvas has no HEIC encoder, so conversion fails locally. Convert AVIF to PNG/JPG/WebP instead — local, unlimited saves.
Bulk Image Format Converter
Convert image batches to JPG, PNG, WebP, AVIF, GIF, BMP, ICO, or SVG outputs (JPEG/PNG/WebP/AVIF/HEIC/HEIF/GIF/BMP/ICO/SVG inputs; HEIC via heic2any, SVG rasterized at intrinsic size or 1024px fallback) with a quality slider (10–100, default 80; applies to lossy encodes). Pair pages (?from/?to) preset the output. Flat ZIP renamed per file — local, 5-file guest batches, 25 signed-in, 500 Pro.
Image Format Converter
Convert one browser-decodable image to PNG, JPG, or WebP — the only outputs canvas can encode. HEIC/SVG/JXL/TIFF and other exotic targets fail honestly instead of pretending. Nothing is uploaded; every conversion runs in your browser.
