Telegram Video Conversion: File Limits, Formats, and Video Circles

Telegram is the most format-flexible consumer messaging platform for sharing files. Its 2 GB file limit, native video player, and document mode let you send virtually anything. But there are still practical constraints: a video that sends fine on Telegram desktop may fail on mobile, the "video message" (circle) format has specific requirements, and very large files need compression before they will upload reliably.

This guide covers the specific conversion and compression workflows for Telegram across its different file-sharing modes.

Telegram File Modes: Video vs Document

Telegram distinguishes between files sent as videos and files sent as documents. The distinction matters for how recipients experience the content.

Video mode: Telegram processes the file on its servers, creates a streaming-compatible version, and shows an inline player. The recipient can scrub through the video before it fully downloads. Requires MP4 or a compatible format.

Document mode: File is sent as-is, with no processing. The recipient downloads the complete file before viewing. Supports any format. Preserves the original file exactly.

When to use each:

• Use video mode for casual sharing, entertainment, clips to watch in-chat
• Use document mode for original-quality footage you want the recipient to have intact, or for formats Telegram does not process as video

To force document mode in the Telegram app, tap the attachment icon, select File, and browse to your video — this bypasses the video processing pipeline.

Telegram Video Requirements and Limits

For reliable video mode playback on all Telegram clients (desktop, iOS, Android), use MP4 with H.264 and AAC audio. H.265 works on newer devices but older Telegram clients or devices without H.265 decode fall back to downloading the original rather than streaming.

Video Circles (Video Messages)

The video circle format — circular, autoplay, loop, no sound — is one of Telegram's distinctive features. It looks like a circular GIF but is actually a silent MP4 with a specific aspect ratio and duration.

Technical requirements for video circles:

• Aspect ratio: 1:1 (square)
• Duration: Up to 60 seconds
• Format: MP4, preferably H.264
• The circle shape is applied by the Telegram client — the actual file is a square MP4

To create a video circle from existing footage, you need to:

1. Square-crop the video (1:1 ratio, centered on the subject)
2. Trim to under 60 seconds
3. Export as MP4 H.264

Using FFmpeg to prepare a video circle:

ffmpeg -i input.mp4 \
  -vf "crop=min(iw\,ih):min(iw\,ih),scale=480:480" \
  -t 60 \
  -c:v libx264 -crf 23 -preset fast \
  -an \
  video_circle.mp4

• crop=min(iw\,ih):min(iw\,ih) — Square crop (uses the shorter dimension)
• scale=480:480 — Resize to 480×480 (Telegram's optimal circle size)
• -t 60 — Limit to 60 seconds
• -an — Remove audio (circles are silent)

In the Telegram app, send as Video to trigger circle format. If you send a square silent MP4 via attachment → Video, Telegram recognizes it and displays it as a circle.

Compressing Videos for Telegram

The 2 GB limit sounds generous until you are trying to send a 4K recording from a modern camera, which can run 200+ MB per minute. For reliable upload and download on mobile connections, target 30–50 MB per minute of video.

For Social Clips (Under 5 Minutes)

ffmpeg -i input.mp4 \
  -c:v libx264 -crf 26 -preset fast \
  -vf "scale=1280:720" \
  -c:a aac -b:a 128k \
  -movflags +faststart \
  compressed_for_telegram.mp4

This targets roughly 10–20 MB per minute at 720p — comfortable for mobile sharing.

For Longer Recordings

For recordings over 15 minutes, use the video compressor for a web-based option, or use a lower bitrate CRF:

ffmpeg -i long_recording.mp4 \
  -c:v libx264 -crf 28 -preset slow \
  -vf "scale=1920:1080" \
  -c:a aac -b:a 96k \
  -movflags +faststart \
  compressed_1080p.mp4

CRF 28 at 1080p produces roughly 5–8 MB per minute for typical screen recordings and talking-head videos.

Splitting Large Videos for Telegram

If a video is over 2 GB (or you want to split a long recording into episodes for sequential sharing), FFmpeg handles segment splitting precisely:

# Split into 30-minute segments
ffmpeg -i long_video.mp4 \
  -c copy \
  -map 0 \
  -segment_time 1800 \
  -f segment \
  -reset_timestamps 1 \
  segment_%02d.mp4

For a visual approach to splitting at specific timestamps, the video trimmer handles the cut points without re-encoding.

Audio Files on Telegram

Telegram treats audio files differently based on format:

• MP3, M4A, AAC files sent as files → appear as inline audio players with waveform
• OGG voice messages → appear as voice message bubbles with transcription option
• Other audio formats → sent as document downloads

To optimize an audio file for Telegram's inline player:

# Convert to MP3 for universal compatibility
ffmpeg -i audio.wav -c:a libmp3lame -b:a 128k telegram_audio.mp3

# Or FLAC for lossless archiving sent as document
ffmpeg -i audio.wav -c:a flac lossless_archive.flac

For compressing audio files before sending, the MP3 compressor reduces file size while maintaining acceptable quality. To extract audio from a video to send as standalone audio, the extract audio tool outputs MP3 or AAC directly.

Sending Documents: Format Strategy

When sending files for someone to edit or work with rather than just view:

Important: Telegram automatically compresses images sent as photos. To send a full-quality PNG or JPG without compression, send it as a File (document mode), not as a Photo. This is critical for images that need to be printed or used in design work.

Telegram Bots and the API

If you are building a Telegram bot that sends media, the API has specific requirements:

Bot API Media Limits

Photos: 10 MB
Videos (via URL): 20 MB
Videos (local upload): 50 MB
Documents: 50 MB
Animation (GIF): 1 MB
Voice: 1 MB
Audio: 50 MB

For sending large video files, the bot must upload to Telegram's servers first and use the resulting file_id for subsequent sends. Direct URL sending only works for files under 20 MB.

Converting for Bot API Delivery

For video content sent via bot, target under 20 MB if using URL delivery:

ffmpeg -i source.mp4 \
  -c:v libx264 -crf 30 -preset fast \
  -vf "scale=640:360" \
  -c:a aac -b:a 64k \
  -movflags +faststart \
  bot_video_small.mp4

This produces roughly 2–5 MB per minute at 360p — well under the URL delivery limit for short clips.

GIFs on Telegram

Telegram converts GIF files to silent MP4 for playback efficiency. A GIF you upload is re-encoded to MP4 on Telegram's servers and plays as a "GIF" (actually a muted looping video). This means:

• Send the GIF as-is and Telegram handles conversion
• Or pre-convert to MP4 for more control over quality: the GIF to MP4 converter handles this cleanly
• Use the video converter to create a silent looping MP4 if you want to control the compression yourself

For creating GIFs from video clips to share on Telegram, the GIF maker tool produces optimized GIFs. Keep them under 1 MB for the best performance in the bot API context.

Frequently Asked Questions

Why does my video show a thumbnail but not play in Telegram?

The video is likely in a format Telegram does not stream natively (MKV, WebM, AVI, or H.265 on older clients). Convert to MP4 H.264 and re-send, or send as a document if you want recipients to have the original file.

Can I send 4K video on Telegram?

Yes — Telegram supports 4K video in both video and document modes. For reliable streaming on the recipient's end, keep the bitrate reasonable (30–60 Mbps maximum). Very high-bitrate 4K files are better sent as documents.

Does Telegram compress videos I send?

When you send a file via the Video attachment type, Telegram re-encodes it for streaming at lower quality. To avoid this, send as a File (document mode) instead. The file will be downloaded rather than streamed but quality is preserved.

How do I send a video as a video circle (video note)?

In the Telegram mobile app: press and hold the microphone icon in the chat compose bar, then drag it to the camera icon. This switches to video note mode. Alternatively, send a prepared square MP4 via attachment → Video. You cannot currently send pre-made video circles through the desktop app's interface.

What is the maximum file size for Telegram premium?

Telegram Premium increases the upload limit to 4 GB per file, compared to 2 GB for free accounts.

Conclusion

Telegram is generous with file formats and sizes compared to other messaging apps, but a few practical conversions make a significant difference. Converting to H.264 MP4 ensures inline streaming on all clients. Compressing before upload ensures reliable transfer on mobile connections. For the video circle format, the square-crop and 60-second limit are the only real constraints.
