Image Requirement ToolFLAGSHIP
Resize, convert and target a maximum image file size.
Make an image meet a target
Resize dimensions, change format, and target a maximum file size using browser-side processing.
Method
Dimension reduction and compression are different: halving width and height leaves 25% of the original pixel area. The same-scale preview makes that relationship visible.
Example
For strict upload limits, try preserving dimensions first; reduce dimensions only if compression alone cannot meet the target.
