I sometimes send photos to groups for use on social media, and non-technical users often struggle with uploads or resize/crop the files badly. I export from darktable and can control pixel dimensions, file type, compression, colour profile, and optional styles such as crops, borders, or watermarks. What settings are most useful for common social platforms, and what should I prioritize when preparing files for others to upload?

None of 1-4 matter. All the major social networks (definitely including Facebook, Twitter and Instagram) re-encode any uploaded photos with their own settings, optimised for their use case (reducing file size/bandwidth) rather than yours. Obviously they can't re-add quality that wasn't there, but they can and will remove any carefully optimised settings you use.
Point 5 (styles) is much more a artistic decision than anything else; if you think your photos look better with a border, add a border - although again remember that the social networks often show a crop of the uploaded image in the main feed rather than the full image.

Generated from our catalog & community — verify before relying on it.
For most social platforms, the main rule is: give them a good-quality file in the format and dimensions they expect, but assume the site will recompress it anyway.
Practical defaults:
- pixel dimensions: use the platform’s recommended size/aspect ratio if known. PPI/DPI does not matter for screen display.
- file type: JPEG for normal photos; PNG only if you specifically need transparency.
- compression: keep quality reasonably high, but stay under the platform’s file-size limit.
- colour profile: use sRGB for web/social use.
- styles: only add crops, borders, or branding if they’re intentional and suit the platform or the group’s house style.
Important caveats:
- Facebook, Instagram, X/Twitter and similar services typically re-encode uploads using their own settings.
- Because feeds often show previews or crops, aspect ratio matters more than fine export tuning.
- For Instagram especially, square and 4:5 portrait images are often practical because they fill more of the mobile screen and are less awkwardly cropped.
So the best approach is usually: export in sRGB as a JPEG, sized to the platform’s recommended dimensions/aspect ratio, with file size under the limit, and avoid relying on metadata like PPI.
