download compression acceleration

A compression (online) service?

Mysteriously, our connection is now very slow (10 KiB/s),
so it takes a very long time to download large files (>= 900 MB).

I'm searching for an online service that will:

  1. Download the original file (given an URL)
  2. Compress it (using GZIP, 7Z, RAR, PAQ, etc.)
  3. Send me a link to a compressed file.
    This way, I can download the compressed file and unzip it.

I tried that with my own VPS and it saves me hours of downloading. Are there any online services that will do this easily?


Most web-servers today implement the gzip compression on the data stream. Perhaps your remote web-server doesn't have that turned on?

Compressing files prior to sending them across the wire will yield little/no improvements on the actual amount of the data going over the wire. Rather than trying to transfer 900mb ... it'd probably be smarter to look at what you're transferring and perhaps look at programs capable of transferring "deltas" rather than the full contents of the files. (transfer what changed vs transferring 100% every time)

I know of no web-services that will do this for you on-the-fly.

  • +0 – I think there are no deltas here. I'm trying to download an ISO of 800 MiB. I don't have any part of the file downloaded yet. So I want someone (with faster connection) to download the file first, and compress it so I have to download less. — Dec 20, 2011 at 18:00
