Click the tray, pick a tool, drop your input — and watch it run, all on your machine. Here's the real app doing exactly that.
The utility belt
What's in the tray
Five focused tools, each doing one job well — all running right on your machine.
Why it's different
Local by design
No cloud in the loop. Spark Tray runs entirely on your machine — so your data stays yours, and stays put.
Private
Your files and URLs never leave your PC.
Instant
No uploads, no queue, no server round-trips.
Yours
No account, no subscription, no lock-in.
Transparent funding
How Spark Tray stays free
Spark Tray is free because you share a little idle bandwidth. While your PC is idle, the app shares unused network bandwidth through a vetted partner— that's what pays for development instead of a subscription.
- Pauses on metered connectionsNever touches a capped or pay-per-GB network.
- Backs off when you're activeYields the moment you need the network yourself.
- Only a small fractionEven while active it uses just a sliver of your bandwidth.
- Always disclosed at installSpelled out up front — no surprises, ever.
Using Spark Tray means opting in. Don't want to share? Uninstalling is the opt-out.

Pulled a whole semester of lecture recordings down as MP3s so I can listen on my commute. Picked the quality, hit go, done. Can't believe this is free.
Marcus R.1 day ago The transcriber turned a two-hour podcast into a clean SRT in a few minutes, timestamps and all. No upload, no signup — it just ran on my laptop. Exactly what I needed.
Priya S.3 days ago Background remover does a genuinely nice job on product shots. Batch mode works but chews through a big folder slowly on my older PC. Still, hard to complain about a free tool that just works.
Dane K.6 days ago What sold me is there's no account and nothing gets uploaded anywhere. It sits in the tray and stays out of my way until I need it. Refreshing after every other app wanting my email.
Emily T.1 week ago works ok for the big sites. one video host i use kept failing tho, wouldnt downlaod at all. format picker was kinda confusing at first too. decent once u figure it out i guess
Jordan M.2 weeks ago Dropped a CSV of 200 links into the bulk downloader before lunch and it was all done when I got back — retried the couple that failed on its own. Saved me an entire afternoon.
Sofia L.2 weeks ago does nothing until u need it. no popups no nagging. keeper
Tomás G.3 weeks ago Transcription accuracy is impressive even on messy audio. Only thing I'd love is speaker labels for interviews — but for the price (free!) I'm not going to grumble.
Hannah B.3 weeks ago transparent png in like 2 seconds. replaced a site i used to pay for lol. reccomend
Wei C.1 month ago our work antivirus blocked the installer so i had to scan it myself and run it on my personal pc instead. worked fine once i did but having to jump through that was annoying
Nate P.1 month ago Love that you can pick the exact resolution and grab subtitles too. Pulled a whole playlist in one go. Does what a dozen sketchy sites only pretend to.
Olivia D.5 weeks ago Solid little toolbox. Only gripe is the update prompt that pops up now and then. Otherwise everythings worked first try so cant complain much
Ravi N.6 weeks ago I transcribe sensitive client interviews and it all stays on my machine — nothing leaves. That local-only approach is exactly why I switched from a cloud service.
Grace H.2 months ago wasnt expecting much from a free tray app but this thing rips. use the downloader and transcriber almost every day now. no complaints
Ben F.2 months ago told my whole team about it. no license keys, no catch that i could find. genuinely useful
Chloe W.10 weeks ago this one app replaced like 3 sketchy ad filled websites i used to dread opening. downloads, bg removal, transcripts all in one tray icon. wish id found it sooner tbh
Aiden M.3 months ago the background remover just nukes the whole background, theres no way to pick what stays. i wanted to remove one person from a group photo and highlight just them like i can on my iphone but you cant. its all or nothing. disapointing
Lucia A.3 months ago it extracted the text from my long video. fast af
Sam O.4 months ago runs fine, does what it says. only knocking stars off cause theres no mac version yet. please make one?
Farah J.4 months ago Checked that the installer was properly code-signed before running it, and it was. Little details like that plus the honesty about how it's funded earned my trust.
