Batch JPEG XL to JPG

Convert a batch of JPEG XL (JXL) images to JPG or PNG in one local pass. Your browser decodes them where it can, and elsewhere a bundled open-source decoder runs locally — nothing is uploaded.

Supports: JPEG XL (batch)
Maximum: 50 MB per image

Every selected file is converted in one local pass; failures are listed and do not stop the batch. Animated JXL exports its first frame.

JPEG XL decode usually uses the bundled open-source jxl-oxide decoder, downloaded on first use. License: MIT / Apache-2.0 · source.

Private: processing happens locally in your browser.

How it works

  1. Choose or drop one or more JXL images
  2. Select JPG or PNG as the output format
  3. Convert the batch and download the results

Use cases

  • Open JXL archives in editors without JXL support
  • Batch-convert JXL exports for sharing
  • Prepare JPEG XL images for upload forms

Supported formats

Input: JXL

Output: JPG, PNG

Limitations

  • JPEG XL support is still rare in browsers, so a bundled jxl-oxide decoder (MIT/Apache-2.0) is usually downloaded on first use.
  • Animated JXL files export the first frame only.
  • Colors are converted to standard sRGB, so wide-gamut colors may shift slightly.

Privacy

Processing happens locally in your browser. Your file is not uploaded to iAgent7 Tools or a third-party API.

File names, file contents, and results are not sent to analytics or error logs.
