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 BMP
What is a BMP file? An uncompressed raster image format. It stores color data for every individual pixel, resulting in extremely high quality but massive file sizes.
How to open a BMP file? Microsoft Paint, Windows Photos, Apple Preview, and almost any image viewer/editor.
Typical use of a BMP file: Historically used as the standard Windows graphic format. Today, it is rarely used outside of legacy software or specific programming environments.
Origin of the BMP file: Developed by Microsoft in the 1980s for the Windows operating system.
Modern alternatives for BMP: PNG provides the exact same lossless quality but with efficient compression, making files a fraction of the size.
