Convert HEIC to AVIF
Convert iPhone HEIC photos to AVIF, a similarly efficient format the open web actually supports.
Free workspace
Keep repeat file work in motion after the first export.
Start here without an account, then move into retained files, OCR, and starter workflows when the task stops being a one-off.
Instant use
25 browser conversions / day
Retained files
7-day retained files
Secure processing
10 server jobs / month
Document tools
20 OCR pages / month
Conversion surface
Run the file task now.
The converter stays fast and simple. Workspace features only step in when retention, OCR, or repeat work actually adds value.
How it works
A short path from input to finished export.
The flow stays simple so you can get in, finish the job, and move on without extra setup.
Upload HEIC Photos
Drag and drop HEIC photos straight from your iPhone, iPad, or Mac. Batch upload is supported.
Adjust Quality
Use the quality slider to balance file size against fidelity. The default of 75% suits most images.
Download AVIF
Save the converted file right away. Multiple images are bundled into a ZIP for one-click download.
Why FileMorf
A cleaner route for this conversion.
The tool keeps the core job lightweight while still giving you room to grow into retained, higher-value workflows later.
100% Private
All processing happens in your browser. Your files never leave your device.
Best-in-Class Compression
AVIF's AV1-based encoding produces the smallest files of any mainstream image format, with transparency support.
Batch Processing
Convert multiple files at once. Download as a convenient ZIP file.

The important questions, plus the nearby routes users usually need next.
AVIF is essentially the web's answer to HEIC: comparable compression built on the royalty-free AV1 codec instead of HEVC, and viewable in Chrome, Firefox, Edge, and Safari 16+. It is the best target for publishing iPhone photos online without giving up small file sizes. Note that AVIF encoding runs in your browser and requires a recent Chromium-based browser such as Chrome or Edge.
Marginally, at most. HEIC is itself a lossy format, so converting to AVIF is a re-encode between two efficient codecs. FileMorf decodes the HEIC at high fidelity and encodes AVIF at a quality level where differences are effectively invisible for photos.
HEIC is Apple's default camera format (iOS 11 and later), built on the HEVC video codec. Windows needs paid codec extensions to display it and support elsewhere is inconsistent, which is why converting to a mainstream format is usually the fastest fix. FileMorf decodes HEIC directly in your browser — no codec installs needed.
Similar sizes — HEIC (HEVC) and AVIF (AV1) are closely matched codecs, so you keep the compact footprint while gaining web support.
Yes. Drop in as many HEIC files as you like — each is converted in turn, and the results can be downloaded individually or together as a ZIP archive.
