Smash advertises no size limit on free transfers, but files above 2GB are deprioritized to slower delivery. Transfilio keeps every transfer at full speed and adds browser-side end-to-end encryption.
| Transfilio | Smash | |
|---|---|---|
| Free transfer speed | Full speed on every plan | Files over 2GB get lower priority on free |
| Free tier shape | 5GB storage, 2GB per file | No size cap, but large files are slower |
| End-to-end encryption | Yes — encrypted in your browser | No client-side encryption |
| File request portals | Included on Pro | Not the focus of the product |
| Developer API | Included on paid plans | Separate API pricing tiers |
| Entry paid plan | £9/month (£7 billed annually) | From ~$6/month |
Details as of July 2026; check Smash's site for current terms.
There is no hard size cap on free transfers, but Smash deprioritizes files over 2GB on the free plan, so large transfers can be significantly slower. Transfilio applies no speed deprioritization on any plan.
Transfilio — branded pages on custom domains, file request portals, download notifications, and share-link controls are included, where Smash focuses on simple one-off sends.
