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.
About DNG
What is a DNG file? A universal, openly documented RAW image format. It stores the same unprocessed sensor data as proprietary formats (CR2, NEF) but isn't tied to a specific camera manufacturer.
How to open a DNG file? Adobe Lightroom, Photoshop, and most OS default photo viewers (Windows/macOS native support is very strong).
Typical use of a DNG file: Archiving RAW photos safely. Photographers convert proprietary RAWs to DNG so they can still open them decades later, even if the camera brand stops supporting the old format.
Origin of the DNG file: Created by Adobe in 2004.
Modern alternatives for DNG: None. DNG is intended to be the ultimate, modern alternative to all proprietary RAW formats.
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.
