WeTransfer just changed their ToS to allow them to train AI on any files you transfer through them.

Don't use there service, especially for work that you don't have the right to relicense to them (e.g., commercial work that's exactly the most likely to create the huge files WeTransfer specializes in).

(ETA: this is already going boom so I'm muting it.)

@spectral_shadow @mwl

Just use Send, the continuation of Firefox Send

https://send.vis.ee/

Send

Encrypt and send files with a link that automatically expires to ensure your important documents don’t stay online forever.

@mwl zip file with password?

@utf_7 @mwl Zip bomb with its own ToS?

Edit: Do not do this. It is unlikely work and if it does they can afford more lawyers than you can.

@noodle @mwl uh, that is even better
@mwl There is better option called pCloud Transfer: https://transfer.pcloud.com/
Send large files up to 5GB for free

With pCloud Transfer you can send large files to anyone, no registration needed!

pCloud Transfer
@rejzor I would not use this because of point 7. https://transfer.pcloud.com/privacy.html
@mwl
Send and download large files, no registration needed

With pCloud Transfer you can download large files without registration for free! You can also send your own files to your colleagues and friends.

pCloud Transfer

@Morpurgo @mwl That's because they have servers in US (Texas) and EU (Germany). As new user you can pick which ones you want to use, before this they defaulted to US and you could later migrate to EU for a small fee.

At least that is applicable for their account storage, can't say what's the default for pCloud Transfer.

pCloud AG is a Swiss company otherwise.

Offering alternatives in posts like this is always a good idea. Adding to the list already cumulating below this post: https://nowtransfer.de by @adminforge ! <3

Bye, WeTransfer

Recommended File Sharing:

switching.software

@mwl i use my #Nextcloud Instance. To Share any File with Full Control over it. Also i can create Dropoff Link if needed. So the Recipient of the Link can Upload the Files secure and directly to me.

In my company i see that some customers use #swisstransfer as alternative.

@mwl i gave it up a long time ago because of the number of scammers who use the site
@mwl First it was "surveillance capitalism". Now it's "the kleptonet". Hide your wife! Hide your children! They stealing from everyone out here!

@mwl

Gotta be kidding…

@mwl In case someone needs a tl;dr:

> You hereby grant us a perpetual, worldwide, non-exclusive, royalty-free, transferable, sub-licensable license to use your Content for the purposes of operating, developing, commercializing, and improving the Service or new technologies or services

> Such license includes the right to reproduce, distribute, modify, prepare derivative works based upon, broadcast, communicate to the public, publicly display, and perform Content.

Thanks for sharing the relevant quote from their terms of service. I was going to ask what kind of language one has to look out for because there's no "training", "LLM", or "artificial" to be found.

Wondering how many times I may have "accepted" terms like these already 😓

@oliver_schafeld here you go:
> including to improve performance of machine learning models that enhance our content moderation process, in accordance with the Privacy & Cookie Policy. Such license includes the right to reproduce, distribute, modify, prepare derivative works based upon, broadcast, communicate to the public, publicly display, and perform Content. You will not be entitled to compensation for any use of Content by us under these Terms.

The combination of those sections is alarming

Terms of Service; Didn't Read

'I have read and agree to the Terms' is the biggest lie on the web. Together, we can fix that.

@stealthradek @mwl Don't like the 2nd paragraph. What's a tl;dr:?

@llanciawn @mwl It's a internet term for cutting the garbage out and pointing straight to the core. I didn't wanted for folks to have to read the entire policy so I've extracted the juice and posted directly here.

TL;DR - Wikipedia

@mwl Another alternative https://wormhole.app/

They do claim end to end encryption, so they should not be able to access your data. I have not validated this myself but have somewhat trust in the backing company.

Still if you are going to use a public file sharing service I would always make sure to add my own layer of security if and when it is needed.

Wormhole - Simple, private file sharing

Wormhole lets you share files with end-to-end encryption and a link that automatically expires.

Wormhole
@mwl I use Send, which is a fork of Firefox Send.
Official instance: https://send.vis.ee
Other instances: https://github.com/timvisee/send-instances/
Send

Encrypt and send files with a link that automatically expires to ensure your important documents don’t stay online forever.

@mwl just use it to transfer large text books of your field of study from laptop to desktop!
@mwl @sandradejong I've recently switched to https://swisstransfer.com that seems to be a good alternative. It accepts larger files and you've got more time before the links expire.
SwissTransfer - Send large files securely and free of charge

Send up to 50 GB - Free and without registration - Keep your transfers for up to 30 days.

@JosKleverWebSupport @mwl @sandradejong I second that. I receive a few dozen transfer each week and all who are currently using WeTransfer are being recommended to use Swiss Transfer instead.
@mwl I think it's on 6.3 and 6.4 of the license (non USA version)
@mwl can anyone recommend good alternatives that don't abuse your data?

@alstonvicar @mwl I’ll toss mine in here https://wsend.net

I also wrote a wrapper to end-to-end encrypt your file with gpg

https://github.com/abemassry/wsend-gpg

@abemassry @mwl thank you very much! It's so good to know there are alternatives to selling your soul!
@mwl *only for improving moderation

@mwl

Ah, WeTransfer the file-sharing transfer service! What an unexpected change in your ToS! And by unexpected, I mean, COMPLETELY EXPECTED!

You are probably wondering if there are any viable alternatives to file transferring services that don't rely on the use of artificial intelligence to steal data? Well, BEHOLD! MY WARPINATOR, AH HAHAHAHAHAHA! With it, I will be able to transfer files seamlessly from one device to the other on the same network without any delay!

@mwl very good to know for translators too, thanks. I've only ever received files that way, once or twice, never sent them but now I know not to in future.

@mwl
If you are a researcher* in the Netherlands and want to send large files, you can use SURFfilesender instead of #wetransfer.

Up to 2GB file size (and up to 1TB with HTML5 browsers) - for free!

Don't let your #researchdata end up as unauthorized AI training data, use #OpenSource based solutions instead.

*or anyone else with SURF access

@NilsArlinghaus @mwl Not only researchers. Maybe @SURF can respond with a more specific description of the group that has access to SURFfilesender. Many of them are not aware. With the latest news about #WeTransfer I think it's a good idea to tell/remind many about SURFfilesender again.

@steltenpower @mwl @SURF

Very good point. I've also updated my post.

@mwl That's why it's free...
Graham Sutherland / Polynomial (@[email protected])

to be specific: no, the WeTransfer ToS doesn't say they'll sell your stuff to AI people. it has a bunch of completely regular ToS boilerplate and then says they may use your stuff as part of internal machine learning models used to identify illegal content, which is entirely normal and reasonable for a file host. as usual it's just a company doing a regular legal language update and someone who doesn't know how to read ToS language has misinterpreted it as being nefarious.

chaos.social
@mwl it does not say that? In the ToS it says "You hereby grant us a royalty-free license to use your Content for the purposes of operating, developing, and improving the Service, all in accordance with our Privacy & Cookie Policy." and in the privacy policy it says "Only with your permission, we may review User Content to identify interesting trends and insights on our users’ behaviors and needs."

@uniwuni @mwl

Is that an extra tick box or if you don't tick the box to grant us a free licence we will not send the file?

@mwl sounds to me like we should be using that service to send AI generated media to each other to help speed up model collapse!

For those that are unaware, AI models trained on datasets made up of AI generated data produce lower quality outputs, which is a rapidly growing challenge for AI companies to manage

@mwl Does this also apply to EU users as I saw they have different terms of service? (most likely not)
@mwl 1/4 we had this response from WeTransfer when we raised concerns:

Our updated Terms, which will come into effect on August 8, 2025 for existing customers, include a revised section outlining the license WeTransfer needs to operate and improve our service. We want to reassure you that we have not changed how we handle your content in practice, nor do we use machine learning or any form of AI to process files shared via WeTransfer.
@mwl 2/4 In an earlier draft of the Terms, we had included a reference to the potential future use of AI for safety measures like content moderation. This was never intended to imply that we would process user content through AI systems, but we now see that the language raised valid concerns. Based on the feedback we received, we’ve removed this reference entirely and simplified the language to make our intentions clearer:
@mwl 3/4 6.3. License to WeTransfer. In order to allow us to operate, provide you with, and improve the Service and our technologies, we must obtain from you certain rights related to Content that is covered by intellectual property rights. You hereby grant us a royalty-free license to use your Content for the purposes of operating, developing, and improving the Service, all in accordance with our Privacy & Cookie Policy.
@mwl 4/4 For context, our previous Terms of Service already included a similar license under section 10.5. While the wording has been updated, the substance and purpose of the license remain the same—it simply allows us to deliver the service reliably and improve it over time, without changing how we treat your files.

@mwl The Beeb is saying that because of the backlash, #WeTransfer have changed their ToS again to remove the "training" language and emphasise that they don't sell or make available our content to others: https://www.bbc.co.uk/news/articles/cp8mp79gyz1o

No idea if that's true, but I can't now find the language I'm pretty sure I saw earlier!

WeTransfer says files not used to train AI after backlash

Some social media users had threatened to delete their accounts after WeTransfer's terms were updated.

BBC News

@mwl If anyone is reading the answers, the #WeTransfer ToS do not actually say that they are using the users' data to train genAI models, see more explanations here and in the comments:

https://chaos.social/@gsuberland/114856595954614172

However, following the outrage they have clarified (narrowed the scope of) their ToS so maybe that's for the best?

@mwl can nextcloud be used for that?

@mwl

Alternatives to #WeTransfer

#Wormhole, which is encrypted and direct, apps like #iyox or #Warp work great.

#FirefoxSend (now only send), encrypted and hosted by some providers or self-hostable.

@alternativeto

@mwl Ouch. I think an alternative to them that would actually get used and make sense would have to be a hosted service with at least a free plan, and would have to use end-to-end encryption (encrypted/decrypted on the web browser side). Wonder if @CryptPad has something, as this is their speciality. Or what they would recommend?
@quite nope, it's quite outside of our field. We do realtime collaboration! File storage in CryptPad with our drive is just a mean to organize your documents. However, it's really not fit for large file sharing! @mwl
