About this tool

Wide-angle interiors almost always keystone: verticals lean, door frames taper, and rooms look like trapezoids. This tool applies a manual 4-point correction — place corners, preview, export a keystone-corrected JPEG — similar in spirit to Lightroom’s upright workflow without the catalog overhead.

Use it when one hero kitchen or living room needs a clean vertical fix before MLS upload. Interactive preview keeps the correction honest: you control how aggressive the warp is so proportions stay believable for buyers.

Need the same fix on an entire listing automatically? The FOCAL RAYS editor applies perspective, color, and exposure across every photo in a job. Free tool = one frame, manual; paid editor = batch, preservation-first.

After correction, run JPEG Compressor or MLS Ready so the file still meets board size and color rules. Pair with Before / After Slider if you want a client-facing comparison still.

Shoot with the camera level when you can; free correction fixes moderate keystone better than extreme wide-angle lean from a low corner.

FAQ

Is this automatic upright?
This free tool is manual (you place corners). Automatic batch upright is part of the paid FOCAL RAYS editor.
Will it stretch people or furniture?
Any perspective warp can distort if pushed hard. Use modest corrections and preview before export.
What output do I get?
A keystone-corrected JPEG suitable for listing delivery after you check dimensions in MLS Ready.
When should I use the editor instead?
When you have a full multi-room set that all needs geometry and color — the editor does the batch, not one frame at a time.

Ready for AI listing polish?

Free tools handle prep. The editor runs perspective, color, exposure, HDR, and twilight with preservation-first rules — nothing staged.
