Conversion from basic group is permanent — no rollback without deleting the group
| Area | ✦ Benefits & features | ⚠ Risks & downsides |
|---|---|---|
| Scale & membership | ||
| Member limit | + Up to 200,000 members vs. 200 in a basic group | − Larger groups are harder to moderate and keep cohesive |
| Discoverability | + Can have a public username — findable via Telegram search | − Public groups can attract spam, bots, and unwanted members |
| Administration & moderation | ||
| Admins | + Multiple admins with granular, per-permission role control | − More admin complexity — accidental permission changes harder to undo |
| Member restrictions | + Per-user restrictions (e.g. mute voice, block media) without a full ban | − Fine-grained settings require more ongoing management effort |
| Admin log | + Recent actions log for full audit trail of admin activity | − No equivalent for basic groups — a gap if you've been relying on simpler oversight |
| Slow mode | + Rate-limit how often members can post to reduce spam | − Can frustrate active users; triggering slow mode itself converts the group |
| Content & history | ||
| Chat history | + New members can optionally see full message history from day one | − Pre-conversion messages may appear as a separate, unjoinable ghost chat in some clients |
| Message links | + Direct links to individual messages — shareable and citable | − Not available in basic groups, so existing workflows relying on that may break |
| Pinned messages | + Multiple pinned messages; topics for organised threaded discussion | − — |
| Bots & automation | ||
| Bot support | + Bots work fully and can be promoted to admin; much more reliable than in basic groups | − Group ID changes on conversion — any bot or integration using the old ID breaks until reconfigured |
| Technical & structural | ||
| Group ID | + New supergroup is technically a new entity — clean slate for integrations | − Old group ID is retired — Zapier, webhooks, bots referencing it must all be updated |
| Member limit counter | + Basic groups are excluded from the 500-group membership cap per user | − Supergroups count toward the 500-group limit (1,000 for Premium) — members may hit caps |
| Boosts | + Supergroups can receive boosts to unlock perks | − Basic groups cannot be boosted at all |
| Deletion | + — | − Supergroups cannot be deleted by the owner — only abandoned (left). The group persists. |
| Irreversibility | ||
| Rollback | + Can switch back to private visibility at any time (group stays a supergroup) | − One-way only Conversion cannot be undone. Only option is deleting and recreating the group from scratch. |
| Silent conversion | + Happens seamlessly with no downtime for members | − Conversion is automatic and silent — no confirmation prompt, can catch admins off guard |
