Are my images uploaded anywhere when I flip them?

No, flipping happens entirely in your browser using the canvas API. The source image is decoded, flipped, and re-encoded locally without any network requests.

What is the difference between a flip and a rotation?

A horizontal flip mirrors the image (left becomes right) — it cannot be reproduced by any rotation. A 180° rotation does both axes at once and is equivalent to a horizontal flip followed by a vertical flip.

Why do selfies often need to be flipped?

Phone front cameras mirror the preview so the image looks natural while you compose it, but most save the un-mirrored capture. Flipping horizontally restores the mirrored look the photographer saw in the viewfinder.

Does flipping reduce image quality?

No. A flip just reorders the same pixels — there is no resampling, blurring, or quality loss as long as the output format matches the input.

Can I flip both axes at once?

Run the tool twice: flip horizontally first, then run the result through again with vertical selected. The combined operation is equivalent to a 180° rotation.

How to use this image flipper

Choose an image file from your device.
Pick "Horizontal" to mirror left-to-right (great for selfies) or "Vertical" to mirror top-to-bottom.
Press "Flip Image" to render the mirrored result onto a canvas.
Preview the output and click "Download" to save the flipped file locally.
Change the direction or pick another image to flip again.

About this image flipper

An image flipper mirrors a picture along its horizontal or vertical axis. A horizontal flip swaps left and right (so a face looking left now looks right); a vertical flip swaps top and bottom (turning the image upside down without changing its left-right orientation). Selfies often need a horizontal flip because phone front-cameras mirror the preview but save the un-mirrored image, so a flipped copy matches what the user saw.

This tool decodes the source image with createImageBitmap, creates a canvas at the original dimensions, applies a CSS-style scale(-1, 1) for horizontal or scale(1, -1) for vertical, draws the image, and exports the result. The flip is exact — no resampling, no quality loss, just a reordering of the pixels.

Everything runs locally in your browser. The image is decoded, flipped on a canvas, and re-encoded without any network request — your file never leaves the tab.

As a worked example, flipping a 1080 × 1080 px square portrait horizontally produces an identical-size file with the subject mirrored left-to-right. Flipping vertically produces the same file with the subject upside down. Both operations are lossless when the output format matches the input, because no resampling is required.
