Rotate & Flip Image

What Rotate & Flip Image does

Rotate & Flip Image turns a picture in quarter turns and mirrors it. Press the buttons until the preview looks right, then save it as JPEG, PNG, or WebP.

The preview is the transform itself, drawn on a canvas rather than tilted with a stylesheet, so what is on screen is what the download holds — including the sides swapping over after a quarter turn.

When a picture arrives the wrong way up

Use it when a photograph comes off a phone sideways, when a scan is upside down, or when a screenshot from another device arrives rotated. Most of these are pictures whose orientation was only ever a tag in the file, and the tag did not survive the trip.

Mirroring is a different job from turning: flip a photograph of a page you shot in a mirror, or a selfie that reads back to front. Rotating and mirroring can be combined, and a picture straightened here can be cropped or resized afterwards in the same Flow.

What each button does

Four buttons, and the picture is only ever drawn once from the original pixels.

Rotate left and rotate right

A quarter turn each way. Four presses in the same direction bring the picture back to where it started rather than stacking four transforms, and after one or three of them the width and the height swap over.

Flip horizontally and flip vertically

Mirrors what you are looking at, left to right or top to bottom. Pressing the same flip twice returns exactly to where you started, whatever rotation is already applied.

Put it back

Returns to the picture as it arrived. It is available only once something has actually changed, so the button never claims to undo nothing.

Output format

JPEG for photographs, WebP for the web, PNG for screenshots and anything with transparency. A turn is lossless in itself — no pixel is resampled — but the file is encoded again, so a JPEG saved as a JPEG is compressed a second time.

Turned here, not somewhere else

The image is decoded, drawn in its new orientation, and encoded by this browser, and the result goes straight to your downloads. Gizlet is a static site with no upload endpoint, so there is nowhere for a photograph to be sent, and nothing is kept once the tab closes.

Every press redraws the preview from the original pixels rather than from the last preview, so pressing a button ten times costs the picture nothing. The file is written once, when you save it.

Because the output is drawn fresh onto a canvas, it also arrives without the metadata the original carried, including the orientation tag that may have been the whole problem, the camera model, and any GPS coordinates.
