Complete Guide: Transfer Large Files Using SHAREit APK Without Quality Loss

Published: 27 Jul 2025

Introduction

SHAREit, a widely used app, stands out from other services due to its unique connection method. This method enables devices to communicate directly, similar to a local Wi-Fi network, ensuring that when you send a file, it arrives exactly as intended, without any loss of quality. It’s a straightforward way to transfer pictures, videos, and other large files quickly and easily.

How SHAREit Preserves File Quality

SHAREit maintains original file quality through several key mechanisms:

Direct Wi-Fi Transfer: Uses Wi-Fi Direct or hotspot connections rather than internet-based transfers
Bit-for-Bit Copying: Files are transferred exactly as they are, without any compression
No File Alteration: Only metadata (such as filenames) may be modified, not the actual content
Original Resolution Maintenance: Videos, photos, and multimedia files retain their original resolution and fidelity

Complete Transfer Process

Phase 1: Pre-Transfer Setup

Device Preparation:

Ensure both devices have sufficient storage space
Close unnecessary background applications to free up RAM
Keep devices charged or connected to power for large transfers
Update SHAREit to the latest version on both devices
Disable battery saver mode to ensure full Wi-Fi performance

Network Optimization:

Disconnect from other Wi-Fi networks (SHAREit creates its hotspot)
Ensure devices are within 10 meters of each other
Remove physical obstructions between devices
Choose off-peak hours for large transfers to avoid network interference

Phase 2: Connection Establishment

For Mobile-to-Mobile Transfer:

Open SHAREit on both devices
On the sender Device: Tap “Send” and select files
On the receiver Device: Tap “Receive”
Wait for devices to appear in the scanning list
Select the target Device to establish a connection
Confirm the connection on both devices

For PC Connection:

Use the “Connect to PC” feature
Enable Wi-Fi on both devices
Follow the QR code or manual connection process
Verify connection establishment

Phase 3: File Selection and Transfer

File Selection Best Practices:

Select files in smaller batches for massive transfers (>10GB)
Organize files by type for easier management
Check available storage space before initiating transfer
Avoid selecting system files or protected content

Transfer Initiation:

Browse and select the desired large files
Tap “Next” to initiate the transfer
Monitor transfer progress without interruption
Keep devices unlocked during the transfer process

Optimization Settings for Quality Preservation

Critical Settings to Disable:

Turn off “Smart Transfer” mode (may compress media)
Disable “Save Data” options
Avoid “Fast Transfer” modes that might compress files
Turn off “Optimized Transfer” if available

Recommended Settings:

Choose “Original Quality” for media files
Select “Keep original resolution” for videos
