Upload a `.heic` or `.heif` file, choose optional size and AVIF compression settings, start the conversion, and download the `.avif` result when processing finishes.
HEIC to AVIF Converter
Convert HEIC to AVIF when an iPhone or iPad photo needs a modern .avif output for supported browsers and web workflows. Upload one .heic or .heif image, keep the original size or set new dimensions, choose lossy or lossless AVIF, and download the converted file.
What This HEIC to AVIF Converter Does
This tool reads an uploaded HEIC or HEIF image and exports the visible still image as AVIF. It is useful when the original photo came from an Apple device, but the copy you need to publish, test, or deliver should be an AVIF file.
| Input | Output | Available settings |
|---|---|---|
| `.heic` image | `.avif` image | Width, height, lossy or lossless AVIF |
| `.heif` image | `.avif` image | Width, height, lossy or lossless AVIF |
| Original photo size | Same-size AVIF | Leave width and height blank |
| Large source image | Resized AVIF | Set width, height, or both up to 16384px |
Use it when you need `.heic to .avif` conversion for a real image file. Do not rename the extension manually; a renamed HEIC file still contains HEIC image data, while this page creates an actual AVIF output.
How to Convert HEIC to AVIF Online
1
Upload a HEIC or HEIF image
Choose a `.heic` or `.heif` file from your device, or drag it into the upload area. These files often come from iPhone and iPad cameras when High Efficiency capture is enabled.
2
Choose AVIF output settings
Leave width and height empty to keep the original dimensions. Enter a target size when the AVIF file needs to fit a web layout, preview area, or asset library. Then choose lossy AVIF for smaller files or lossless AVIF when fidelity matters more.
3
Convert and download the AVIF file
Start the conversion and wait for processing to finish. The result is a downloadable `.avif` image that you can use in AVIF-aware browsers, apps, and delivery workflows.
HEIC vs AVIF: Why the Conversion Helps
HEIC and AVIF are both modern image formats, but they are used in different places. HEIC is common on Apple devices. AVIF is commonly used for modern web delivery where small files and current browser support matter.
| Format | Common use | Practical note |
|---|---|---|
| HEIC / HEIF | iPhone and iPad camera photos | Good source format, but not accepted everywhere |
| AVIF | Modern web images and delivery copies | Efficient output for browsers and apps that support AVIF |
That is why a HEIC AVIF workflow often makes sense: keep the original HEIC photo as your source, then create an AVIF copy for the place where you need to use or test AVIF.
AVIF Settings That Matter
Choose the AVIF settings based on the output you need. Lossy mode is useful when file size matters, lossless mode is better when you want the result closer to the uploaded image, and resizing helps when the source photo is larger than the final display size.
| Setting | What it does | When to use it |
|---|---|---|
| Lossy AVIF | Creates smaller AVIF files by using lossy compression | Use it when file size is the main priority |
| Lossless AVIF | Keeps the AVIF output as close as possible to the uploaded image | Use it when fidelity matters more than file size |
| Quality 30-40 | Prioritizes smaller AVIF files | Thumbnails, previews, and less detailed images |
| Quality 50 | Balanced default setting | Start here if you are not sure |
| Quality 60-80 | Keeps more visible detail | Larger photos, product visuals, screenshots, and images with fine detail |
| Width and height | Resizes the output during conversion | Use it when the original HEIC photo is larger than the final place where the AVIF will be displayed |
The maximum output dimension setting is 16384px. AVIF is efficient, so a lower quality value can still look good at normal display sizes.
HEIF to AVIF Support and Limits
This page accepts both `.heic` and `.heif` inputs. HEIF is the broader image format family, while HEIC is the Apple photo variant many users see on iPhone and iPad files. For this tool, both are in scope as input formats for AVIF output.
Keep these limits in mind before you write the output into a production workflow:
One image workflow
Upload one file and download one AVIF result
One-way conversion
This is not an AVIF to HEIC converter
Still image output
Do not use this page to promise animated HEIC or HEIF handling
Advanced source data
Do not assume every metadata, HDR, or device-specific feature will carry over
Backend processing
Uploaded files are processed on the backend and scheduled for deletion within 24 hours
If the destination does not accept AVIF, keep the original HEIC file and choose a different output format with a dedicated converter instead of forcing this page to cover another workflow.
Frequently Asked Questions
No. Renaming `.heic` to `.avif` changes only the file name, not the image data. A real `.heic to .avif` conversion must decode the HEIC image and export a new AVIF file.
Yes. The upload field accepts both `.heic` and `.heif` files, so it can be used as a HEIF to AVIF converter when your source file uses the `.heif` extension.
HEIC is commonly used for photos from Apple devices. AVIF is commonly used as a modern web image format. Both can compress images efficiently, but AVIF is often chosen for delivery in browsers and apps that support it.
Convert HEIC to AVIF when you want an AVIF copy of an iPhone photo for web testing, image delivery, or a workflow that specifically asks for `.avif` files.
Lossy AVIF can reduce file size by discarding some image data. Use a higher quality setting or lossless mode when visual fidelity matters more than file size.
Yes. You can leave the original size unchanged or enter a new width, height, or both before conversion. The maximum size setting is 16384px.
Yes. Choose lossless mode when you want the AVIF output to stay closer to the uploaded image. Choose lossy mode when smaller files matter more.
No. This page only converts HEIC or HEIF input to AVIF output. It does not convert AVIF files back to HEIC.
Use a dedicated output page for that format, such as HEIC to PNG, HEIC to JPG, or HEIC to WebP. This page should stay focused on HEIC to AVIF conversion.
