Lorem Ipsum Text File Generator (1 KB to 500 MB)
Download a plain-text .txt file of lorem ipsum at an exact size: 1 KB, 50 KB, 1 MB, 10 MB, 200 MB or anything in between. The file is built in your browser, so nothing is uploaded and large files are created in seconds.

What you get
- Exact byte size. The file is pure ASCII (one byte per character), so a 50 KB file is exactly 51,200 bytes and a 1 MB file is exactly 1,048,576 bytes. Choose the 1,000-based units if your system uses decimal kB/MB.
- Real paragraphs. Text is split into paragraphs separated by blank lines and ends on a full word, so it behaves like real content when pasted or parsed.
- Large files without freezing the tab. Files over 64 KB are assembled from a repeated 64 KB block of lorem ipsum, which lets the browser create a 200 MB file almost instantly. That repetition is fine for upload limits and storage tests, but note that it compresses very well, so it is not suitable for testing compression ratios.
- Private. The file is generated locally with JavaScript and saved straight to your device.
Common uses
- Testing file-upload size limits (for example, rejecting a file just over 5 MB but accepting one just under).
- Checking how an editor, textarea or API handles very long input.
- Seeding a database column or storage bucket with realistic-looking text.
- Measuring transfer speed or progress bars with a predictable file.
Need a specific number of characters or words rather than bytes? Use the character count or word count generators.
FAQ
Is 1 KB 1,000 or 1,024 bytes?
Both conventions exist. Operating systems like Windows and most upload validators treat 1 KB as 1,024 bytes, while storage vendors and macOS Finder use 1,000. Pick the unit that matches the system you are testing.
What is the largest file I can generate?
Up to 500 MB. Very large files depend on your device having enough free memory and disk space.
Why does my 1 MB file show as slightly different in my file manager?
File managers often round sizes or use a different unit base. Check the exact byte count in the file properties; it will match the number shown here.
