Privacy Without Limits
Smash caps files at 2 GB and lacks true encryption. Stash removes the limits and adds end-to-end encryption so your files stay private.
The encryption difference
Smash encrypts files in transit (TLS), but stores them readable on their servers. This protects against interception, but not against server breaches or internal access. Stash encrypts files on your device with AES-256-GCM before upload. The encryption key lives in your share link—never on our servers. True zero-knowledge privacy.
Why people switch from Smash
2 GB limit on free tier
Smash limits free transfers to 2 GB—the same as WeTransfer. Trying to send a long 4K video or a batch of RAW photos? You will hit that limit fast. Stash has no file size limits, even on the free tier.
Files expire in 7-14 days
Smash deletes your files after one to two weeks. If your recipient does not download in time, the file vanishes and you must re-upload. Stash links stay active until you decide to delete them.
No true encryption
Smash uses TLS encryption during transfer, but files are stored unencrypted on their servers. They can access your content. Stash encrypts files on your device before upload—we cannot see your files even if we wanted to.
Web-only experience
Smash does not have a native mobile app—everything goes through their website. On an iPhone, this means navigating Safari, dealing with upload limitations, and a subpar experience. Stash is built natively for Apple devices.

Frequently asked questions
Is Smash better for business use?
Smash offers custom branding for business accounts, which is useful for agencies and enterprises. But if privacy and encryption matter more than branding, Stash is the better choice. Your files are end-to-end encrypted, not just encrypted in transit.
Does Smash have ads?
Smash's free download pages include advertising. Paid plans remove ads and add custom branding. Stash download pages are always clean with no ads, even on the free tier.
Can I send files larger than 2 GB with Stash?
Yes. Stash has no file size limits. Send 5 GB, 20 GB, or larger—the only limit is your patience during upload. Files stay encrypted and links never expire.
