Correct perspective distortion online
A tilted camera makes rectangular pages and objects look like trapezoids. PixelOkay Image Perspective Fixer remaps a selected quadrilateral into a flat rectangle using a projective transformation. You can straighten scans, photographs of printed documents, whiteboards, signs, posters and many other planar subjects. Import images and export PNG, JPEG or WebP locally in your browser.
Limits of perspective correction
Perspective correction is most accurate for flat, planar surfaces. It cannot reconstruct hidden details, remove motion blur, recover low-resolution text or accurately flatten curved book pages. Automatic corner suggestions use contrast heuristics and may require manual adjustment. For sensitive material, no image data is sent to PixelOkay servers by this tool.
Using Image Perspective Fixer
Flatten a photographed planar subject by mapping four reviewed corners to a rectangle, then inspect the resampled image before saving.
Workflow
Open a supported image and correct orientation
refine four corners around one flat surface
set proportions and scale, inspect edges, then export PNG, JPEG, WebP or an embedded-image project.
Example
Align a photographed poster’s four corners to its edges, choose landscape proportions, inspect for clipping, and export PNG.
Limits and data handling
This corrects planar perspective; it does not flatten curves, remove blur or restore hidden detail. Corner suggestions are heuristic. Inputs cap at 18 MiB/24 MP and outputs at 16 MP/8192 px with 0.25x–2x scale. Recovery is opt-in in browser storage; verify orientation and encoders on-device.
FAQs
Can it flatten a curved book page?
No. The transform models a flat plane and cannot reconstruct curvature.
Are automatic corner suggestions guaranteed?
No. Review and adjust all four corners before export.
