How to Reduce Photo File Size for Telegram Channels

Updated September 27, 2026 · 7 min read

Reducing file size is a sequence, not a single click. Channel posts can reach many subscribers, and lighter images make the feed snappy for all of them.

Recommended settings for Telegram channels

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.

  • Use consistent dimensions for a set of related images.
  • Resize before you compress; it improves quality at any file size.
  • Write a size limit slightly below the stated maximum to leave a margin.
