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 CR3

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 PNG

How to open a PNG file? Universally supported by web browsers, standard OS viewers, and image editors.
Typical use of a PNG file: Web graphics, logos, charts, and illustrations where crisp lines, text, and transparent backgrounds are required.

Modern alternatives for PNG: WebP (Lossless) and AVIF both support transparency but offer significantly smaller file sizes.
