Methodology & calculation rule
Calculate Maximum Centered Inscribed Rectangle of Ratio (W : H) → Extract Sub-Bitmap
Center crop extracts symmetrical borders. Verify the preview if your subject is positioned near the edge of the frame.
All image processing executes client-side within your browser sandbox via HTML5 Canvas and WebAssembly. No photographs, bitmaps, or metadata are ever uploaded to remote servers.
Output files are generated in-memory as local object URLs. Files must be smaller than 20 MB and under 24 megapixels.
Real-World Context & Technical Standards
16:9, 4:3, 1:1, and 9:16 Framing
Common digital video and display standards (16:9 widescreen, 4:3 tablet/presentation, 1:1 social square, and 9:16 mobile story/Reel) dictate precise aspect ratios for optimal visual framing.
Preserving Real Object Proportions
Center-cropping extracts the largest centered rectangular bounding box matching the requested proportion without stretching, squeezing, or altering the physical geometry of people and objects.
Previewing Edge Discards
Because preset center-cropping discards perimeter pixels equally from opposite edges, inspecting the interactive canvas preview confirms that critical text or off-center subjects remain intact.
