Compressing Scanned Pages for X (Twitter) Posts

Updated July 25, 2026 · 7 min read

Scanned pages are often saved at very high resolution. Timelines move fast, and an image that loads instantly is more likely to be seen before someone scrolls past.

These are practical defaults. If the platform or form you are using publishes its own limits, follow those instead.

Compressing Scanned Pages

A page scanned at 600 DPI can be over 5000 pixels tall. For reading on screen, around 1600 pixels wide is enough.

Text on a white page compresses efficiently, so a target of 400 KB is usually achievable while staying sharp for X (Twitter) posts.
