What Smash is
French file-transfer service known for unlimited file size on the free tier.
Smash is the WeTransfer alternative that markets unlimited file sizes on free. The catch is that large free transfers are slower, ad-supported, and that the company pushes you toward paid plans for protection, branding, and retention controls.

Frequently asked
Is Smash really unlimited?
Practically, no. Smash advertises no size cap on free, but very large transfers are slowed and surrounded by upsells. For files under 5 GB the speed advantage of paid services like quik.space is usually noticeable.
Why does Smash show ads on the download page?
The free tier is funded by display advertising. quik.space takes the opposite approach: the free tier is funded by paid uploads from people who need extends, larger files, or shared spaces.
Can I send 50 GB on quik.space?
Not in a single file. The current XL upload caps at 5 GB. If you need to send 50 GB, MASV or Filemail are better fits.
Does Smash train AI on user uploads?
Smash has no public statement either way as of this writing. quik.space's policy is explicit: we do not train AI on user files.
