Detailed User Guide
Step 1: Upload Your Image
Click anywhere in the upload area or drag and drop an image file. Supported formats include JPG, PNG, WebP, GIF, and BMP. The image loads instantly and appears in the preview canvas. No data is sent to any server — everything stays in your browser.
Step 2: Choose Your Transformation
You have several options for transforming your image:
- Quick Rotate: Click "90° Left" or "90° Right" for common quarter-turn rotations. Use "180°" to flip the image upside down. These are the most common rotations for fixing photos taken in the wrong orientation.
- Custom Angle: Drag the angle slider from 0° to 360° for precise rotation at any angle. The current angle is displayed below the slider. Great for straightening tilted photos or creative effects.
- Flip: "Horizontal" creates a mirror image (left-right flip). "Vertical" flips the image top-to-bottom. These are perfect for creating reflections, mirror effects, or correcting scanned documents.
Step 3: Fine-Tune the Result
The preview updates in real-time so you can see exactly how your image will look. When rotating by custom angles, the canvas expands to fit the entire image. You can choose a background color to fill the new corners that appear after rotation. Set it to white for printing, black for dark themes, or use the color picker to match any background.
Step 4: Download
When you're happy with the result, choose your output format (PNG for quality, JPG for smaller files, WebP for modern use) and click "Download". The file saves to your device immediately — no watermarks, no quality loss, no server uploads.
Best Use Cases
- Fix photo orientation — Rotate sideways or upside-down photos from your camera roll
- Straighten tilted photos — Use the custom angle slider to fine-tune the horizon line
- Mirror selfies — Flip horizontally to create a true mirror reflection
- Creative compositions — Rotate at unusual angles for artistic effects
- Scanned documents — Flip or rotate scanned pages that came in the wrong orientation
- Social media prep — Rotate landscape to portrait or vice versa for different platforms
Pro Tips
- For quick orientation fixes, use the 90° buttons — they're faster than the slider
- When rotating by custom angles, choose a background color that matches your target background
- PNG format preserves transparency — if your image has a transparent background, use PNG
- You can combine rotation and flipping — rotate first, then flip for unique effects
- Use "Reset" to go back to the original orientation without re-uploading
- For straightening photos, try small angles (1-5°) and watch the preview closely
