How to rotate or flip an image with OnyxPDF
- Drop your photos into the tool.
- Use the 90° buttons, flip buttons, or type a free angle.
- Check the live preview.
- Click “Rotate Images” and download the fixed photos.
Why do it in your browser instead of uploading?
- Free-angle rotation for the “almost straight” shots that quarter turns cannot fix.
- Flips included: un-mirror selfies and scanned film in the same tool.
- Batch: fix a whole camera dump of sideways photos in one pass.
- No upload, full resolution preserved.
Good to know (honest limits)
- Free-angle rotation grows the canvas (corners are filled) — for exact framing afterwards, crop the result.
- Rotation is baked into the downloaded copies; originals are untouched.
Frequently asked questions
How do I un-mirror a selfie?
Use Flip Horizontal. Front cameras save mirror images; one flip restores the true orientation (text on shirts reads correctly again).
What does the free angle do to the corners?
The canvas expands so nothing is cut off, and the new corner triangles are filled — crop afterwards if you need a clean rectangle.
Can I rotate many photos at once?
Yes — the same rotation applies to the whole batch.
Are photos uploaded?
No. Rotation is a local canvas transform.
