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 HEIC
What is a HEIC file? Apple's proprietary version of the HEIF (High Efficiency Image File) format. It uses advanced video compression algorithms to store photos at high quality taking up half the space of a standard JPG.
How to open a HEIC file? Natively on Apple devices (iOS 11+, macOS High Sierra+). On Windows, it requires installing a specific HEVC extension from the Microsoft Store.
Typical use of a HEIC file: The default photo format for modern iPhones and iPads.
Origin of the HEIC file: Based on the HEVC (H.265) video standard developed by the MPEG group, adopted by Apple in 2017.
Modern alternatives for HEIC: For universal web sharing, HEIC files are almost always converted to JPG or WebP.
