When this tool is useful
Correcting sideways photos, scans, screenshots, and graphics before sharing or using them in another workflow.
How local processing works
The browser decodes each image, draws its pixels onto a canvas rotated 90° clockwise, swaps width and height, and encodes a new file in the source format.
How to use it
- Choose the source files.
- Review the available settings and page order.
- Process locally, inspect the result, and download it.
Important limitations
The output is re-encoded rather than losslessly changing an orientation flag. Metadata and animation are not preserved, and repeated JPEG saves can add compression loss.
Private by design
Your files stay in this browser. The tool does not upload the source or output to our servers.
Questions and answers
Does this tool upload my files?
No. Processing happens in your browser; closing the page clears the working session.
Will the output always match the source exactly?
The output is re-encoded rather than losslessly changing an orientation flag. Metadata and animation are not preserved, and repeated JPEG saves can add compression loss.
Concrete input and output example
Input a 3024×4032 JPEG that appears sideways, choose 90° clockwise, and export a 4032×3024 corrected copy. Inspect the result because it is re-encoded rather than merely changing the EXIF orientation flag.
Browser compatibility notes
Reviewed against the implementation and required web APIs on 2026-08-12. Use a current browser where these APIs are available and verify important output on your device.
- Chrome / Edge (current desktop)
- Requires local decode, canvas, encoding, Blob download, and enough memory; verify the downloaded image.
- Firefox (current desktop)
- Uses the same standard local APIs; color rendering can differ slightly from Chromium.
- Safari (current desktop)
- Uses canvas and Blob downloads; available memory and codec behavior remain WebKit-controlled.
A tool-specific question
Does rotation preserve the original image bytes?
No. The browser draws decoded pixels onto a rotated canvas and encodes a new file, so metadata can be removed and lossy formats can change slightly.
