Image Straightener is a free online tool that fixes tilted and crooked photographs instantly. Rotate photos with precision angle control from -45° to +45° to correct misaligned horizons, straighten building perspectives, and level landscape shots. The alignment grid overlay helps achieve perfect horizontal and vertical alignment, while auto-crop automatically removes transparent corners after rotation.
Upload your crooked image to begin straightening. Drag the rotation slider left or right to adjust the angle in 0.1-degree increments for precise alignment. Enable the alignment grid to visualize horizontal and vertical reference lines across your image - perfect for lining up horizons with the grid. Toggle auto-crop to automatically trim empty corners, or disable it to keep the full rotated canvas with custom background color.
The alignment grid displays horizontal and vertical guide lines overlaid on your image, making it easy to match horizons, building edges, or water lines to perfect horizontal alignment. Use manual rotation for precise correction of slightly tilted smartphone photos (typically 1-3 degrees), severely crooked scanned documents requiring larger adjustments, or architectural photography needing exact vertical alignment for building straightness.
Use image straightening for landscape photography with tilted horizons that need leveling, smartphone photos taken at slight angles without grid assistance, scanned documents and receipts that fed through crooked, real estate photos where walls and doorframes must appear perfectly vertical, or product photography requiring precise horizontal surfaces. Straightening improves composition and gives photos a more professional, intentional appearance.
Auto-crop intelligently removes the transparent triangular corners that appear after rotation, keeping only the largest rectangular area containing full image data - ideal for social media posts and website graphics requiring clean edges. Disable auto-crop to preserve original dimensions with custom background fill: choose white for printed materials and documents, black for artistic dark compositions, or transparent PNG for layering in graphic design applications. Export straightened images up to original resolution in PNG format for lossless quality or compressed JPG/WebP for web optimization.
