Straighten Sideways Photos by Any Angle

Phones store a hidden orientation tag instead of actually turning the pixels, so a photo that looks fine in your gallery can appear sideways on a website, in an email or inside a PDF. PDFWix Rotate Image physically rotates the pixels 90°, 180° or 270° and can mirror images horizontally or flip them vertically — perfect for selfie cameras that save reversed text. The corrected photo displays the right way up everywhere.

When to rotate or flip an image

How to Turn a Picture the Right Way Up

  1. Add photos — Drop the sideways or mirrored images into the upload box.
  2. Pick a rotation — Choose 90°, 180° or 270° clockwise, or None if you only want to flip.
  3. Flip if needed — Switch on Flip horizontally to mirror, or Flip vertically to turn upside down.
  4. Download — Click Rotate images. The fixed files keep their original format.

Quick answer

To rotate an image free: open PDFWix Rotate Image, add your photos, choose 90°, 180° or 270°, optionally switch on flip horizontally or vertically, and click Rotate images. The corrected photos download immediately.

How PDFWix Rotate Image works

PDFWix Rotate Image first decodes each photo with its EXIF orientation applied (createImageBitmap with imageOrientation "from-image"), then draws it onto a canvas rotated by the chosen angle and optionally scaled by −1 on either axis to mirror or flip it. For 90° and 270° rotations the canvas width and height are swapped. The result is saved in the original format, so the orientation is baked into the pixels and no longer depends on metadata.

Why photos show up sideways

Cameras write the image sensor data in a fixed direction and add an EXIF Orientation tag saying how it should be turned for display. Gallery apps read that tag; many upload forms, older email clients, CMS editors and document tools ignore it or strip it, which is why the same picture can appear rotated. Rotating the actual pixels fixes the problem permanently. Mirroring (flipping horizontally) is a separate fix. Front-facing cameras often save a reversed image, so text on a T-shirt or sign reads backwards. A horizontal flip puts it the right way round. A vertical flip turns an image upside down along its horizontal axis — handy for reflections and design work.

Frequently asked questions

How do I rotate an image 90 degrees?

Add the photo, choose 90° and click Rotate images. Choose 270° to rotate 90° anticlockwise.

How do I mirror a photo?

Set rotation to None and switch on Flip horizontally, then click Rotate images.

Does rotating reduce quality?

PNG stays lossless. JPG and WebP are re-saved at 93% quality, which is visually identical.

Why does my photo still look sideways in some apps?

The original relies on a hidden orientation tag. PDFWix bakes the rotation into the pixels so every app shows it correctly.

Are my photos uploaded?

No. Everything happens in your browser.

Is it free?

Yes, free with no watermark.
