Exactly 6144 KB
ResizeBox interprets 6 MB as 6291456 bytes using binary units.
High-Resolution Capacity
The large allowance can preserve fine texture, smooth tonal changes and broad pixel dimensions.
Automatic Quality Matching
The encoder chooses JPEG quality from the source rather than exposing a fixed manual control.
Resolution Reduction Is Conditional
Dimensions decrease only when quality adjustment cannot move a large JPEG toward 6 MB.
One Consistent JPEG Result
JPG, PNG and WebP inputs are exported as JPEG, so transparency is flattened.
Large Images Stay Local
Processing occurs inside the browser without transferring the original file to ResizeBox.
