Converting HEIC to JPEG for Telegram Channels

Updated May 22, 2026 · 7 min read

iPhones save photos as HEIC by default, and not every site accepts it. 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.

Converting HEIC to JPEG

When you pick photos through the browser file picker, iOS usually converts them to JPEG automatically. On other systems, open the HEIC in your photo app and export as JPEG.

Once you have a JPEG, compress it to around 400 KB for Telegram channels. JPEG is accepted almost everywhere.

Step by step with TheCompressJPEG

  1. Open the compress JPEG to 300 KB tool, or the main compressor for custom settings.

  3. Set the maximum width to 1600 and the target size to 400 KB.
  4. Press Compress, check the result and download it.

  • Resize before you compress; it improves quality at any file size.
  • Write a size limit slightly below the stated maximum to leave a margin.
