Why Your Images Are Too Large for X (Twitter) Posts
If an upload keeps failing, the image is usually larger than it needs to be in more ways than one. Timelines move fast, and an image that loads instantly is more likely to be seen before someone scrolls past.
Recommended settings for X (Twitter) posts
| Setting | Starting point |
|---|---|
| Format | JPEG (WebP where accepted) |
| Width | about 1600 px on the long edge |
| Quality | 78 |
| File size | 400 KB or less |
These are practical defaults. If the platform or form you are using publishes its own limits, follow those instead.
Why Your Images Are Too Large
Modern cameras capture 12 to 50 megapixels. That detail is useful for printing posters but rarely for X (Twitter) posts, where about 1600 pixels wide is plenty.
Metadata, PNG format for photos, and maximum-quality saves also add weight. Re-encoding as JPEG at quality 78 after resizing solves all three at once.
