Convert Images in 4 Simple Steps
Quickly transform your images with our streamlined conversion process. Every file is processed through a scalable background queue with real-time status updates — so you can convert hundreds of images at once and watch each one move from In queue to Processing to Ready. No software installation required.
Upload Image Files
Click 'Choose Files' or drag & drop your images into the upload area. Supports multiple files at once.
Select Format & Settings
Choose your target format (WebP, PNG, JPG, etc.) and adjust quality, size, and other conversion options.
Queued & Converted
Click 'Convert All' and each image is queued and processed in the background. Track live status for every file — In queue, Processing, then Finalizing — updated in real time.
Download
As soon as a file is Ready, download it individually or grab everything as a ZIP. Queued processing keeps large batches going even with hundreds of images.
How the Image Converter Works
Drop your images, pick a target format, and convert. Every file is queued and processed in the background with real-time status — In queue, Processing, then Ready — so you can convert hundreds of images at once without the page freezing.
From HEIF to AVIF: Consolidating Formats into Modern Open Standards
HEIF (High Efficiency Image Format), standardized by MPEG in 2015, is a flexible container designed to hold compressed images from various codecs — including Apple's HEVC variant (HEIC) and implementations from some Android manufacturers and camera makers. While HEIF achieved its goal of being an efficient, flexible container, support remains fragmented: it's proprietary-variant-dependent and not widely adopted outside specialist ecosystems. AVIF, released in 2019 by the Alliance for Open Media and built on the AV1 codec, offers what HEIF promised: dramatic compression, broad support, and future-proof standardization backed by Google, Mozilla, and the open web community. Converting HEIF to AVIF consolidates fragmented formats into a modern, broadly-supported standard.
Why Convert HEIF to AVIF?
HEIF's main problem is fragmentation: different manufacturers implemented different codecs within the HEIF container, so a HEIF file works perfectly on the device that created it but may not work elsewhere. AVIF sidesteps this by standardizing on AV1 compression within a single well-defined format. Converting HEIF to AVIF means moving from a format that's technically efficient but practically fragmented into one that's both efficient and universally supported.
From Manufacturer-Specific to Truly Universal
HEIF represents a transitional format between older standards and the modern web. AVIF is the future: it's the format recommended by Google, supported natively by modern browsers, and backed by international open-web standards organizations. Converting your HEIF images to AVIF ensures your photos work reliably across devices, platforms, and future software generations.

HEIF vs AVIF: Key Differences
| Feature | HEIF | AVIF |
|---|---|---|
| Released | 2015 | 2019 |
| Compression | Flexible container, codec-dependent efficiency | AV1-based, ~50% smaller than JPEG |
| Transparency Support | Full alpha channel available | Full alpha channel support |
| Animation Support | Codec-dependent (HEIC doesn't, some variants do) | Supported in AVIF containers |
| Browser/Software Support | Limited, fragmented by variant (Apple, some Android, cameras) | Modern cross-platform (Chrome, Firefox, Edge, Safari) |
| Best Use Case | Variant-specific ecosystems (Apple devices, some cameras) | Universal modern web delivery and cross-platform compatibility |
