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.
