How to Make an sRGB Upload Copy from a Wide-Gamut Photo
By ImgHeal · Updated
Keep the wide-gamut source and convert a duplicate to the destination's documented color space in a color-managed editor. For a web-oriented sRGB copy, use conversion rather than simply relabeling the file. Inspect saturated regions afterward, embed the intended profile where supported, and verify the actual exported image before upload.

Confirm source and destination roles
Read the embedded profile and note whether the file is a retained scan, an edited master, or a previous export. Check the uploader's current requirements rather than assuming every service preserves every profile. A wide-gamut source can remain useful for editing even when a standard viewing copy is more convenient. Do not replace it with the upload derivative or assume that the larger gamut proves the photograph contains more authentic scene detail.
Convert a duplicate with a preview
In separate software such as Photoshop, choose the documented Convert to Profile workflow and select the appropriate destination. Preview the effect on saturated clothes, flowers, painted objects, and skin before committing. Avoid assigning sRGB to numbers encoded for another space. If a color changes noticeably, record the limitation and consider a restrained adjustment on the derivative. There is no universal setting that guarantees every possible source color will reproduce identically on every viewer's screen.
Verify the saved file, not just the editor
Export the format accepted by the next workflow and check dimensions, orientation, appearance, and the retained profile. Reopen the local export independently. If uploading for restoration, compare the service's source preview with that file before attributing a later color difference to the model. Keep the upload name tied to the master through a source note. A compatible copy is a delivery preparation step, not evidence that historical or generated colors are correct.

Questions about this restoration task
Will sRGB make every device look identical?
No. It provides a common interpretation for many web workflows, but display capability, color management, brightness, and viewing conditions can still differ.
