Best Image Format for Web, Print, and Social Media — They're Not the Same
Guide · Image Tools
Web, print, and social media each have a different bottleneck they're optimizing against — web cares about file size and load speed, print cares about physical resolution and color accuracy, and social media cares about platform-specific dimensions and compression the platform applies on its own. Using one universal "high quality" export for all three usually means it's wrong for at least one of them.
For the web: small file, screen resolution
Web images only need enough resolution to look sharp at their actual display size on a screen (roughly 72-150 pixels per inch equivalent, depending on display density), and JPG or modern formats like WebP at moderate compression keep file size low, which matters directly for page load speed and search ranking.
For print: high resolution, CMYK-aware color
Print needs considerably higher resolution — 300 DPI at the final printed size is the standard target — because paper and fabric show far more physical detail per inch than a screen does. File size barely matters for print the way it does for web, but color accuracy does, since CMYK's more limited color range means what looked right in RGB can shift once printed.
For social media: match the platform's own crop and compression
Social platforms apply their own compression on top of whatever you upload, and they crop to their specific aspect ratios regardless of what you send — uploading a huge, uncompressed master file doesn't protect quality, since the platform recompresses it anyway, and it can slow down your own upload for no benefit. Export at the platform's actual recommended dimensions and a reasonable JPG quality rather than the largest file you can produce.
Keep one high-quality master, export the rest from it
The practical solution to needing three different outputs is keeping a single high-resolution, uncompressed (or losslessly compressed) master file, then exporting web, print, and social versions from that master each time you need one — rather than repeatedly re-compressing an already-compressed copy and compounding quality loss across every reuse.
