Frequently Asked Questions
Is my image data safe?
Absolutely. 100% of the conversion processing occurs inside your local web browser sandbox. No file chunks or metadata are transmitted to our servers or stored anywhere externally.
Will transparency be preserved?
Converting to lossless formats like PNG preserves full transparency (alpha-channel). If you are converting to JPEG, any transparent sections are rendered as solid background colors (customizable in output settings).
Can I convert multiple images at once?
Yes, you can drop or select multiple files simultaneously. Our tool processes and triggers the sequential download of all assets with a single click.

How to open them? Adobe Lightroom, Photoshop (via Camera Raw), Apple Photos, or Canon's Digital Photo Professional.
Typical use: Professional photography using Canon cameras, allowing maximum flexibility in post-processing (exposure, white balance).
Origin: Developed entirely by Canon.
Modern alternatives: DNG (Digital Negative) is often used to standardize RAW files across different camera brands.
About JXL
What is a JXL file? The newest evolution of the JPEG format. It is designed to replace legacy JPEG, GIF, and PNG with a single, highly efficient format that supports both lossy and lossless compression, animations, and progressive loading.
How to open a JXL file? Support is currently growing. Apple devices support it natively (iOS 17/macOS Sonoma). Web browser support is still experimental or requires flags to be enabled in Chrome/Firefox.
Typical use of a JXL file: Future web deployment and high-quality photo archiving. It has the unique ability to re-compress legacy JPGs into smaller JXL files without losing any quality.
Origin of the JXL file: Standardized by the Joint Photographic Experts Group in 2021.
Modern alternatives for JXL: AVIF and WebP are its main competitors, currently boasting much wider browser support than JXL.
