Proxy Bandwidth Calculator

Free bandwidth calculator for web scraping and proxy usage. Upload HTML with assets to calculate bandwidth per request. Visualize file types, simulate blocking resources, and estimate costs for large-scale scraping. Perfect for optimizing proxy usage and reducing bandwidth costs.

Upload ZIP File
How this is calculated

Upload a ZIP of a saved page (HTML plus assets). We sum uncompressed file sizes by type, then:

  • Per request = sum of unblocked file types
  • Total bandwidth = per-request size × request count
  • Cost = (total bytes / 1024³) × your $/GB input

Default $1.00/GB is a mid-range planning figure between cheap datacenter bandwidth and higher residential rates. Adjust it to match your provider. Public entry pricing for reference: IPRoyal, Bright Data. This is not a quote — retries, redirects, and compression change real usage.

Request count, $/GB, and blocked types sync to the URL so you can share a pre-filled calculator (ZIP uploads stay local). Model last reviewed . Pair with the scraping stack picker when choosing HTTP-only vs headless browser stacks.
