FAQ

Is the original file uploaded by Batch Image Resize and Converter?

No. The selected file is read and processed only inside your browser.

Does Batch Image Resize and Converter preserve original metadata?

Canvas-redrawn output generally does not include original EXIF metadata. Browser encoders may still differ in color handling or compression.
