How to Reduce Photo File Size for X (Twitter) Posts

Updated March 21, 2026 · 9 min read

Reducing file size is a sequence, not a single click. 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

SettingStarting point
FormatJPEG (WebP where accepted)
Widthabout 1600 px on the long edge
Quality78
File size400 KB or less

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

How to Reduce Photo File Size

First crop away anything that does not belong in the frame. Every pixel you remove is data you never have to compress.

Second, resize to about 1600 pixels wide. Third, compress at quality 78, or set a target of 400 KB. Doing it in this order gives a sharper result than compressing a huge image down to a tiny file in one step.

Step by step with TheCompressJPEG

  1. Open the compress JPEG to 300 KB tool, or the main compressor for custom settings.
  2. Drop in your image. Nothing is uploaded; it is processed in your browser.
  3. Set the maximum width to 1600 and the target size to 400 KB.
  4. Press Compress, check the result and download it.
