Batch Compressing Photos for Telegram Channels
When you have dozens of images, consistency matters as much as size. Channel posts can reach many subscribers, and lighter images make the feed snappy for all of them.
Recommended settings for Telegram channels
| 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.
Batch Compressing Photos
Drop all the files at once. The same settings are applied to each, so a set of photos for Telegram channels ends up with matching dimensions and similar file sizes.
Use Download all to collect everything in one ZIP. A target of 400 KB per image keeps the whole batch predictable.
