4Sync review
A practical 1 TB cloud-storage service with a 60-day trial and paid plans.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
4Sync is a cloud file-storage and synchronization service for individuals who want to store, back up, access, and share documents, photos, music, videos, and other files. It supports web access, Windows and Mac synchronization, and mobile applications for iOS and Android. The service is suited to users who want basic multi-device storage with sharing controls, offline access, backup copies, file recovery, and Android camera uploads rather than a broad collaboration ecosystem.
According to the vendor's pricing page, the Premium monthly plan costs $8.25 per month and includes 1 TB of storage, a 20 GB maximum upload file size, and unlimited bandwidth. The published Premium annual plan includes the same listed storage, upload, bandwidth, synchronization, and sharing capabilities. A 60-day trial gives prospective users time to evaluate the service before committing. Folder permissions support view-only and upload/edit access, while shared folders can be private or public and files or folders can be distributed through direct links.
Platform coverage is one of 4Sync's practical strengths: files can synchronize across computers, tablets, and smartphones, with access through web, Windows, macOS, iOS, and Android. Additional tools include ZIP downloads, file recovery, offline access, and automatic camera uploads on Android. The tradeoff is a narrower ecosystem, with limited integrations compared with storage services built around broader connected workflows. Users seeking straightforward storage, synchronization, recovery, and sharing should consider 4Sync; those prioritizing extensive integrations or ongoing no-cost storage should choose an alternative.
