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 JPEG XL: Upgrading to the Next Generation of Compression
HEIF (High Efficiency Image Format), released in 2015, uses HEVC/H.265 to compress modern photos efficiently. JPEG XL (JXL), standardized in 2021 by the Joint Photographic Experts Group, is the deliberate successor to both JPEG and HEIF — combining exceptional lossy compression, lossless capability, HDR support, animation, and the ability to losslessly recompress existing JPEG files with zero further quality loss. JXL represents the next step in image compression evolution, though browser support is still emerging.
Why Convert HEIF to JPEG XL?
JPEG XL delivers better compression than HEIF while offering both lossy and lossless modes in the same format, plus built-in support for HDR imagery and animation. If you need cutting-edge compression efficiency and can rely on applications that support JXL — or are testing JXL for upcoming platform support — converting HEIF to JXL future-proofs your image workflow.
Backward-Compatible Innovation
Unlike HEIF, JPEG XL can losslessly re-encode any existing JPEG file with zero quality loss, making migration from legacy archives painless. This compatibility, combined with superior compression across all scenarios, positions JXL as the long-term industry standard that organizations investing in image infrastructure should consider today.

Convert in your browser with no account required, and uploaded files are automatically deleted immediately after processing.
HEIF vs JPEG XL: Key Differences
| Feature | HEIF | JPEG XL |
|---|---|---|
| Released | 2015 (MPEG standard) | 2021 (JPEG Committee) |
| Compression | HEVC/H.265-based, ~50% smaller than JPEG | Hybrid codec, better than HEIF; lossless JPEG re-encoding possible |
| Transparency Support | Supported | Supported |
| Animation Support | Supported via image sequences | Supported natively within a single file |
| Browser/Software Support | Apple devices and some professional software; broad on mobile | Safari native; Chrome/Firefox emerging; support still ramping up |
| Best Use Case | Apple-device-centric workflows and modern camera integration | Next-generation web delivery, legacy JPEG migration, HDR content |
Where HEIF and JPEG XL Each Make the Most Sense
Apple Ecosystem Photo Storage
HEIF is optimized for iOS, iPadOS, and macOS, offering efficient compression with native integration into Apple Photos and iCloud.
iPhone & iPad Photo Library
Photos captured on Apple devices are natively HEIF, making it the natural format for managing iOS photo libraries efficiently.
Optimize Images for Future-Ready Websites
JXL offers superior compression compared to HEIF and WebP, making it ideal for photographers wanting maximum quality with minimal file size on next-generation web platforms.
HDR & Professional Photography Portfolios
JXL natively supports HDR imagery and wide color gamut, making it perfect for professional photography portfolios requiring maximum visual fidelity.
Batch Converting Archives to Download as Zip
Convert entire HEIF photo collections to JXL format and download the whole batch as a single zip file for easy archiving or migration.
