About this tool

Listing edits only sell when the improvement is obvious. Load an original and an edited frame, drag the handle to compare, and optionally export a still for email, Instagram, or a client report. Matching aspect ratios look best; different sizes are scaled into the comparison frame.

Use cases: photographer proofing an AI pass from FOCAL RAYS, agents reviewing twilight vs daytime, and QA after perspective or HDR merge. Export a comparison JPEG when you need a static artifact instead of an interactive slider.

This is an inspect/QA tool, not an editor. For the actual preservation-first edit (perspective, exposure, HDR, twilight), open the FOCAL RAYS editor. After comparing, deliver clean files via MLS Ready packs.

Tip: keep labels clear (Before / After) so non-photographer clients understand the story without a phone call.

Keep file sizes reasonable when emailing comparison stills — compress if needed — and never watermark MLS masters the same way you watermark private proofs.

Can I export a still?
Yes — download a comparison JPEG for reports and social proof.
Is this free?
Yes, no sign-up and no watermark on the export.
Where do the edits come from?

Ready for AI listing polish?

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