There are few emails that can stop a project in its tracks faster than this one: "I can't open the file you sent." Suddenly, you’re not a creative director or a project manager anymore; you’re tech support. Is it their video player? Do they have the right version of Excel? It’s a huge, unnecessary barrier to getting good work done. We believe your clients and collaborators should be able to see your work without having to own the software that created it. The feedback process should be about the work itself, not about technical troubleshooting. That’s why our team at MediaFire built @fastdotio with powerful, in-browser previews for just about everything. You can send a single link where your client can stream an HD video, listen to an audio track with a full waveform, flip through a document or presentation, and even scroll through a spreadsheet, all without a single download. It means the feedback loop gets dramatically faster. Your clients can see the work instantly, on any device, and give you the notes you need to keep the project moving forward.

The whole process of getting files from a client is broken. You send an email, they reply with a question, you send a link, they forget the password. It’s a huge amount of friction right at the start of a project. We're fixing this with @fastdotio

We've completely overhauled our audio support, making it easier than ever to share sound files. You now get seamless waveform generation and precise seeking for all your MP3, WAV, and AIFF files. The preview experience is incredibly smooth.

Fast.io is MediaFire if we built it in 2025. We went back to our roots and built the file-sharing experience we want for ourselves. Video rendering, AI summaries, custom logos and backgrounds. It's file sharing, made beautiful.

Early data indicates it's file size limits - how big are these files people? We'll try to support it!

Does this sound familiar? Your team’s knowledge is scattered across emails, Slack channels, multiple cloud drives, and individual computers. It’s a nightmare to find anything, and even worse when trying to leverage AI tools. That’s the problem we’re solving with Fastio.

We’re back! After a hiatus, we’re thrilled to announce something big coming this Friday. Get ready for Fastio, a game-changer in team collaboration and AI.

Hey @digg! Welcome back! The internet's pretty wild now, but we're still here. We've changed a bit since we launched on you in 2006, but we've never forgotten what you did for us. Bet we've still got some of your old files stashed somewhere.
