How to use Camera Lens Distortion Corrector
- Choose a supported photo and set the output dimensions.
- Enter manual radial k1/k2 values and choose the outside fill.
- Review geometry and edges in the generated PNG before using the correction.
Example: Camera Lens Distortion Corrector
A local worked example using the inputs and settings below for camera lens distortion corrector.
You add
Image: ["sample.png (348 bytes)"]
First radial coefficient (k1): "0"
Second radial coefficient (k2): "0"
Output width (px): "80"
Output height (px): "60"
Pixels beyond the source: "transparent"
You get
Created a 80 by 60 PNG using k1=0, k2=0.

Options
- Radial coefficients
- k1 and k2 belong to the stated manual radial model. The tool refuses unsupported non-monotonic settings instead of choosing a lens profile.
- Output and fill
- Dimensions define the resampled raster, and fill controls uncovered areas. Changing aspect ratio can change the displayed geometry.
Supported inputs and limits
JPEG, PNG and WebP within 24 megapixels of input and 2 megapixels of output. Manual radial coefficients only, with supported monotonic mapping bounds. No camera-profile detection or automatic calibration. Resampling can soften detail and leave uncovered edges.
Where your input is processed
This tool processes your input in this browser. Your text and files are not uploaded to UseFreeTools. Check this tool's limits for anything it may save on your device.
Manual correction needs a visual reference
Inspect straight lines or another suitable reference in the original photo. Zero coefficients give the model’s identity case under the chosen dimensions. A visually preferable result does not establish calibrated lens correction.
Questions about Camera Lens Distortion Corrector
Will the tool detect my lens model?
No. You enter the radial coefficients and review the result.
Why can the edges become uncovered?
A distortion map can sample outside the source image. Review the selected border treatment.
Can correction restore missing detail?
No. Resampling uses the pixels already in the uploaded image.
