AI Image Straightening & Perspective Correction
Roomagen Image Straightening is an AI-powered perspective correction tool that fixes tilted horizons, barrel distortion, and wide-angle lens warping in property photos with one click. The output is a level, naturally proportioned photo with straight vertical lines. Processing takes under 90 seconds using 2 credits per image ($0.23–$0.40 depending on plan), with a free plan offering 6 credits.
Wide-angle lenses cause walls to lean, floors to curve, and vertical lines to converge — making rooms look distorted and unprofessional in listing photos. In real estate photography, wide-angle lenses (10-24mm range) are essential because they make small rooms appear spacious, but they introduce multiple types of geometric distortion. Barrel distortion curves straight lines outward at the frame edges, making walls appear to bow. Converging verticals cause parallel walls to lean inward, especially when the camera is tilted upward. Pincushion distortion — common with some zoom lenses — curves lines inward. Horizon tilt from handheld shooting makes the entire scene appear crooked. Buyers who see distorted images subconsciously perceive something wrong with the property, reducing trust and engagement with the listing. Manual correction in Lightroom requires applying lens profiles, adjusting perspective warp controls, and performing guided upright transforms — a process taking 5-10 minutes per image that demands technical expertise. Each lens and camera combination produces different distortion characteristics, requiring individual calibration. Roomagen AI detects and corrects all four distortion types (barrel, pincushion, tilt, converging verticals) simultaneously in a single pass, using architectural reference lines — vertical walls, horizontal ceilings, door and window frames — to calculate precise geometric corrections. Results are delivered in under 90 seconds with minimal cropping.
No credit card required. Results usually in under a minute.

Upload Your Photos
Upload any property photo in JPEG, PNG, or WebP format (up to 50 MB). The tool handles both interior and exterior shots from any camera or lens type — DSLR wide-angle, smartphone, drone, or mirrorless camera. The AI identifies architectural reference lines throughout the image: vertical elements like walls, door frames, and window edges, plus horizontal elements like ceiling lines, floor edges, and countertops. These reference lines form the geometric model the AI uses to calculate and correct all distortion in the frame.
AI Processing
The tool is fully automatic — no lens profiles, manual adjustments, or settings required. The AI simultaneously corrects four types of distortion: barrel distortion (curved edges from wide-angle lenses that make straight lines bow outward), pincushion distortion (inward-curving edges from telephoto or zoom lenses), horizon tilt (rotational misalignment from handheld shooting), and converging verticals (walls leaning inward from looking up at a building). All four corrections are applied in a single pass with intelligent crop minimization that preserves as much of the original frame as possible.
Download Results
Download your corrected photo in under 90 seconds. Walls are vertical, horizons are level, and lens curvature is removed — producing a naturally proportioned architectural photograph that matches what the human eye actually sees in the space. For best results in a multi-tool workflow, apply straightening first before enhancement, HDR, or sky replacement — correcting geometry on the original photo produces the most accurate results, and subsequent tools benefit from working on properly aligned architectural lines.

Common Use Cases
Wide-Angle Lens Correction
Fix the barrel distortion common in wide-angle real estate photography. The AI removes curved edges and restores natural straight lines without cropping significant portions of the image.
Vertical Line Straightening
Correct leaning walls and tilted door frames caused by camera angle or lens distortion. The AI identifies vertical architectural lines and straightens them to produce a level, professional photograph.
Smartphone Photo Repair
Smartphone cameras often introduce subtle distortion that makes rooms look skewed. The AI corrects these perspective issues automatically, producing images that match what the eye actually sees.
Architectural Photography Cleanup
Ensure all architectural lines are perfectly straight for portfolio or marketing use. The automatic correction handles multiple distortion types simultaneously in under 90 seconds.
Drone Photo Correction
Drone cameras frequently introduce lens distortion and horizon tilt that makes buildings appear to lean or landscape to curve. Upload aerial property photos and let the AI automatically level the horizon and correct lens-specific distortion, producing professional overhead shots with accurate architectural geometry and straight property boundaries.
Consistent Listing Photo Set
Process all photos from a property listing through the straightening tool to normalize different distortion levels from different shooting angles. Photos taken with wide-angle in tight bathrooms have more distortion than those shot in open living areas — the AI corrects each appropriately, producing a visually consistent set where all walls are vertical and all horizons are level.
Unlike manual lens correction that requires per-lens profiles and multiple adjustment passes, Roomagen applies all geometric corrections automatically in one step. Lightroom lens correction ($10-55/month subscription) requires knowing your specific lens profile, manually adjusting perspective warp sliders, applying guided upright transforms, and fine-tuning crop — typically 5-10 minutes per image even for experienced editors. Photoshop Transform and Warp tools ($20-55/month) offer more precise control but demand advanced skills and 10-15 minutes per image, with no automatic detection of distortion type. Dedicated tools like PTGUI ($50-200 license) and DxO ViewPoint ($99) specialize in geometric correction but require installation, calibration, and batch processing is limited to similar lens/camera combinations. Mobile apps with auto-correction features produce inconsistent results because they lack real estate-specific training data. Roomagen processes each image in under 90 seconds at 2 credits, automatically identifying architectural reference lines (walls, ceilings, doorframes) and correcting barrel distortion, pincushion distortion, horizon tilt, and converging verticals simultaneously — no lens profiles needed, no manual adjustments, no software expertise required.
