Testfile Reviews 438

Great linkk

I was using this website for couple of days and it is the original speed test website, I can feel the original speed when I download something. In future I expect that they should add file upload option that I just downloaded from the website, when I can also measure my proper upload speed

very usefull, quick and easy!

different file sizes and the right sizes too, 300mb 500mb 1gb + thank you!

Very useful website, no annoying ads, very recommended if you want to test your internet speed

just one word , AMAZING !!

If you work with networks, CDNs, download managers, QA pipelines, video players, or simply need reliable test files, testfile.org is an absolute lifesaver. The site provides a huge range of directly downloadable test files (PDFs, images, MP4 videos, and raw/dummy binaries) in many sizes — from tiny samples up to multi-GB files — so you can simulate real-world cases in seconds without signing in or messing with generators.

Why I love it:

- Instant, no-friction direct links: click and download the exact file size/format you need. Perfect for quick manual checks or automated scripts.
- Wide format coverage: PDFs for rendering tests, MP4s for playback/streaming checks, and binary “dummy” files for bandwidth and throughput validation.
- Real-world throughput testing: use the large files to measure sustained download speeds, CDN behavior, TCP connection stability, resume functionality and download manager reliability.
- Dev & QA friendly: grab a file to use as a fixture for automated upload tests, integrity checks, or to validate storage I/O and write/read performance on devices.
- Great for troubleshooting: reproduce customer reports by downloading identical sample files across networks and locations to compare results.
- Simple, readable pages and obvious links — no clutter, easy to script against.
- No signup or account friction — ideal for on-the-fly diagnostics.

Top use-cases (who should use it):

- Network engineers measuring real throughput and CDN performance.
- QA teams validating file upload/download flows and resume behavior.
- Devs testing HTTP clients, download managers, or error/retry logic.
- Video engineers testing playback/bitrate switching and buffering with real MP4s.
- App devs testing PDF rendering and large document handling.
- QA for storage and I/O: check write/read speeds on devices by downloading/storing large test files.
- Anyone needing reproducible test fixtures for automated scripts or load tests.

In short: elegant, pragmatic and immensely useful. testfile.org removed a lot of friction from our everyday troubleshooting and testing workflows — it’s fast to use, predictable, and covers almost every file-based testing need you’ll have. Highly recommended to anyone who needs reliable test files without fuss.

this is a good website to test download speeds

great website, i like it

I tried downloading the 10GB file along with other sizes over 1GB and they didn't work. Only 1 file worked and it was a 500MB download that I didn't want. The servers are very unstable.

Very helpful tool.

Great website

Really very useful! could not find a proper pdf test file but git it here quickly

I am glad that people still keep website ad free.

That's Really High Speed. Good For Testing Internet Speed

i needed dummy large file for testing, this site helped me, every one should try this

It's really good it downloads fast perfect for testing my little tool
