Flip Image (Horizontal & Vertical)
Mirror images horizontally (left-to-right) or vertically (top-to-bottom). Flips pixel coordinates cleanly without resampling blur.
Best solution
Local processing: Flip Image (Horizontal & Vertical); Lossless coordinate reflection without resampling blur.

Methodology & calculation rule
Horizontal: x′ = width − x − 1; Vertical: y′ = height − y − 1 (Direct Cartesian Matrix Inversion)
Horizontal mirror swaps left and right; vertical flip turns the image upside down. Be cautious with text and directional signage.
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
Horizontal vs. Vertical Cartesian Inversion
Horizontal flip maps pixel coordinate (x, y) to (w - x, y) creating a mirror image; vertical flip maps (x, y) to (x, h - y) reflecting top to bottom without modifying pixel dimensions or canvas aspect ratio.
Correcting Front-Facing Camera Symmetry
Smartphone front cameras often record inverted mirror views of the user. Flipping horizontally restores the true orientation as viewed by an external observer.
Handedness and Legibility Impact
Reflecting an image reverses directional arrows, clocks, and text characters. Mirroring must only be used when typographical content is absent or deliberately intended to read inverted.

Frequently Asked Questions
Does flipping an image reduce image sharpness?
No. Pixel coordinates are mapped orthogonally without fractional interpolation or blur.
Is flipping the same as rotating 180 degrees?
No. A horizontal flip creates a mirror reflection. A 180-degree rotation turns the image upside down without mirroring chirality.
