Flip & Rotate

Flip and rotate are fundamental image transformations. Rotating turns the image by a specific angle, while flipping mirrors it along the horizontal or vertical axis. Both operations rearrange pixels without affecting image quality.

Horizontal flipping creates a mirror image, like looking in a bathroom mirror. It is commonly used to correct selfies since front cameras mirror the image by default. Vertical flipping turns the image upside down.

Formidex supports both 90-degree steps and free angles. You can apply multiple transformations in sequence, for example flipping first and then rotating.

Transformations are executed via the browser's Canvas API. Rotating by 90, 180, or 270 degrees simply rearranges pixels, which happens losslessly and instantly. Free angles require interpolation, which can create minimal blurring.

Transformations are cumulative: flipping horizontally first then rotating 90 degrees produces a different result than reversing the order. The preview always shows the current state before you download the result.

For most corrections, 90-degree steps are sufficient. A portrait photo saved as landscape is fixed with a single 90-degree rotation.

Selfies are captured mirrored by most front cameras. If text in your selfie appears reversed, use horizontal flip to correct the image.

When scanning documents, pages may end up rotated 180 degrees or mirrored. Combine rotation and flipping to restore correct orientation before using text recognition.

Correct photo orientation: cameras store orientation info in EXIF data. When a program ignores this data, the image appears rotated. A quick 90-degree rotation solves the problem.

Fix selfies: the front camera mirrors the image so it feels natural. For publishing or printing, you often want the unmirrored version where text is readable in the correct direction.

Prepare documents: scanned pages are sometimes inserted the wrong way. Instead of repeating the entire scan, simply rotate the affected pages 180 degrees digitally.
