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 JPG

JPG and JPEG are exactly the same format; the three-letter extension was just a requirement of older Windows systems.
How to open a JPG file? Universally supported. It can be opened by any web browser, operating system default viewer (Apple Preview, Windows Photos), and all image editing software.
Typical use of a JPG file: Digital photography, web images, and sharing photos online where small file sizes are prioritized over perfect pixel accuracy.
Origin of the JPG file: Created by the Joint Photographic Experts Group in 1992.
Modern alternatives for JPG: WebP, AVIF, and JXL (JPEG XL) offer better compression and quality at smaller file sizes.
