About this tool
Testing an upload field, a CSV importer or an image cropper always needs a file to throw at it. Grab a ready-made sample here: structured data (JSON, CSV, TSV, XML, YAML, SQL, TXT), images in every common format, or a dummy file of an exact size to test upload limits.
The text and image files are generated on the spot in your browser and downloaded directly — no server, no tracking, no waiting.
Frequently asked questions
Are these sample files safe to download and use?
Yes. Every file is generated on the fly in your browser from plain data or a canvas drawing — there are no macros, scripts, or executables hidden inside, just genuine files in the format you picked.
What license are the sample files under? Can I use them in my own tests?
They're free to use for any purpose, including commercial test suites — no attribution required. They exist specifically to be dropped into upload forms, parsers, and CI pipelines.
Can I get a file of an exact size, to test an upload size limit?
Yes. Use the sized download at the bottom — enter a number and choose KB or MB, and it generates a dummy.bin of exactly that size filled with random bytes.
Are the sample images real photos?
No. They're generated gradients labeled with their dimensions, created in-browser via canvas — genuine, valid image files in each format, just not photographs.
Can I use these in an automated CI/CD test suite?
Yes. The content is deterministic and lightweight, which makes these files well suited to automated upload, parsing, and file-type-detection tests without needing to check binary fixtures into your repo.
