Make a strong impression with your transfer

Make a strong impression

Take advantage of each transfer to promote and enhance your brand. By personalizing your transfers, you make them 100% your own, from their creation to their reception by the recipient. The immersion in your universe starts as soon as the transfer is accessed, via a personalized URL with your name and a customized name for the link, then with your own wallpapers (images or videos) and logo, which is also included in the transfer follow-up emails. Wow effect guaranteed for the recipient! Discover some examples.

Promote your activity through your transfer

Promotional pop-ins

Promote your activity

In addition to customizing the design of the transfers as well as follow-up emails, Smash gives you the opportunity to distribute promotional content during the download time of your files. Your transfers become a real communication tool. For example, broadcast a promotional video of your business...the range of possibilities is endless!

Get peace of mind with your large files

Security & environment

Get peace of mind

In addition to being encrypted, in transit and at rest, and stored closest to you (in London for example), your transfers are always ephemeral. You choose their availability period, then, they are deleted at the end of this period. The days are numbered to access your files and you help reduce the carbon footprint. The planet says thanks for using Smash!

  • We are serious about security - yours and your files. That's why we use engineering tools and practices to secure access to personal data, through encryption techniques that are among the highest standards in the industry. Transfers are encrypted in transit and at rest. Also, to reinforce security and protect against attacks, we have security audits performed by external service providers (Vaadata, NBS System).

    Your transfers can be password-protected, so access the files they contain is top secret. The availability period of your files is also an ally for security: you can use this feature to make your files available for a short period (one day, for example). An effective way to combine spontaneity and security.

    More info about security on our dedicated page, here

  • Smash is committed to reducing its carbon footprint, through the ephemeral availability of all file transfers made on its service. File uploads are always available for a limited time: from 1 to 30 days maximum. Also, through a study to measure its environmental impact, in collaboration with Utopies, Smash has shown that using its service, compared to sending a file by email with an attachment, reduced CO2e emissions by 90% in 2020. Despite its digital-only status and the environmental impact that implies, Smash is an alternative in reducing the impact of digital and CO2e emissions. In short, the planet thanks you for using Smash!

  • After many requests and much patience, our users' wishes have finally been fulfilled: the Smash API is now public. Designed and created for developers, by developers, it aims to offer considerable time savings to teams wishing to send and receive big files via their websites, applications, SaaS solutions, or any custom business cases. The Smash API, which handles petabytes of data from the creation of the file transfer service, integrates in minutes and ensures secure, efficient and reliable file transfers.
