Overview
Introduction
This tool flips a JPG left-to-right, entirely in your browser, with no server upload involved.
It's a pure pixel-column reversal, so the result is a perfect horizontal mirror with no quality loss beyond normal JPEG re-encoding.
What Is JPG Horizontal Flipper?
A client-side JPG horizontal-mirror tool that reverses the order of an uploaded image's pixel columns, so the left edge becomes the right edge and vice versa.
It's the counterpart to the vertical flipper, which mirrors top-to-bottom instead of left-to-right.
How JPG Horizontal Flipper Works
For every pixel at column x, the tool copies its color into column (width - 1 - x) of the output, leaving the row position unchanged.
Because it's a direct copy with no interpolation, there's no blur or artifact introduced by the flip itself.
When To Use JPG Horizontal Flipper
Use it to correct a mirror-flipped selfie-camera photo, create a symmetric or reflected design graphic, or flip a directional subject (like an arrow or a person facing one way) to face the other.
It's often combined with the vertical flipper or a rotation to reach a specific final orientation.
Often used alongside PNG Horizontally Flipper, JPG Vertical Flipper and JPG Orientation Changer.
Features
Advantages
- Runs entirely client-side; nothing is uploaded to a server.
- Lossless pixel rearrangement with no resampling artifacts.
- Instant, one-click operation with no parameters to configure.
Limitations
- Only flips left-to-right; for a top-bottom mirror use the vertical flipper instead.
- Text or asymmetric logos embedded in the photo will read backward after a horizontal flip, since the flip has no awareness of image content.
Examples
Best Practices & Notes
Best Practices
- Combine with the vertical flipper if you need a full 180-degree mirror rather than just left-to-right.
- Check any text or logos in the image before flipping: they'll read backward afterward.
Developer Notes
flipJpgHorizontally mirrors the equivalent PNG-category horizontal flipper exactly, just against the jpg PixelBuffer/JpgToolResult types: a single pass copying each source column into its mirrored output column via the shared getPixel/setPixel helpers.
JPG Horizontal Flipper Use Cases
- Correcting a mirrored front-camera selfie photo
- Flipping a directional subject to face the opposite way
- Creating a symmetric or kaleidoscope-style design graphic
Common Mistakes
- Flipping a photo that contains readable text or a logo, which then reads backward.
- Confusing a horizontal flip with a rotation: a flip alone doesn't change the top/bottom orientation.
Tips
- If you need a true 180-degree mirror (both axes), use the rotator tool at 180 degrees instead.
- Pair with the vertical flipper for creative kaleidoscope-style effects.
