Flip Image Horizontally

Flip Image Horizontally reverses the image across a vertical axis: left becomes right while top and bottom stay in place. Canvas translates by output width, scales x by −1, and redraws pixels. Text and asymmetric symbols are mirrored too, and source metadata is not preserved.

Quick answer

Is horizontal flip the same as rotation?

No. It changes handedness like a mirror rather than turning the image.

Horizontal reflection reverses x coordinates

For an image width W, a point at x maps to approximately W−x in the reflected coordinate system.

How it works

Choose one image. The canvas keeps original dimensions, applies a negative x scale after translation, draws the bitmap, and exports PNG.

Key concepts

Handedness changes

Logos, gestures, road signs, and products can acquire incorrect meaning.

Dimensions remain unchanged

Only pixel positions reverse.

When to use it

  • Create a mirrored composition.
  • Correct a reversed scan when appropriate.
  • Compare left/right layout balance.

When not to use it

  • Do not flip readable text unless mirroring is intended.
  • Do not use it to correct EXIF orientation generally.
  • Do not assume physical scenes become factually equivalent.

Worked examples

Portrait

Input
Person facing left
Expected output
Person appears to face right

The entire frame is mirrored.

Text sign

Input
EXIT
Expected output
Mirrored letters

OCR meaning can be impaired.

Transparent PNG

Input
Asset with alpha
Expected output
Mirrored PNG with rendered alpha

Canvas keeps transparent pixels.

Common mistakes

Calling it rotation

Reflection changes chirality. Correction: Use Rotate Image for turning.

Ignoring text

Every pixel is mirrored. Correction: Inspect labels and logos.

Assuming metadata stays

A new PNG is encoded. Correction: Preserve metadata separately.

Best practices

  • Check text and directional cues.
  • Keep the original.
  • Use only when mirror semantics are acceptable.
