How to Send High-Quality HD Photos in Telegram: 4x Resolution Mode, Attachment Menus & Lossless Files
Stop aggressive image compression in its tracks: discover how Telegram's High Quality (HD) mode delivers 4 times the pixel density of standard uploads, and when to utilize lossless file attachments for bit-perfect photography.
Crystal-Clear Imagery Without Clunky External File Sharing
Standard mobile messaging apps compress images aggressively down to 1280px or lower, obliterating fine text, landscape textures, and facial details. Telegram offers a versatile three-tier photo transmission architecture: standard compression for rapid chatting, High Quality (HD) Mode which quadruples the active pixel count up to 2560px on the longest dimension, and Lossless Document Transmission which transfers raw camera DNG/RAW files up to 2GB (or 4GB for Premium) with untouched EXIF metadata.
4x Higher Pixel Density
High Quality mode unlocks 2560px resolution with 4 times the active pixels of standard photos, preserving sharp text on documents and screenshots.

Tap the HD button inside the photo editor or select 'Send in High Quality' directly from the attachment menu before dispatching.
Send as Uncompressed File
