Broken images and wrong file extensions for testing
Uploads often fail on real files: truncated images, a .jpg that is really a PNG, rotated phone photos, or CMYK from print. Here you can create exactly those test files.
Check failure cases early
Use damaged images and files with the wrong extension to check validation, error messages, and what the UI shows — before real users hit them.
Rotation and metadata
Phone photos often store orientation in EXIF. With the generators and the image inspector you see what is in the file and what remains after stripping metadata.
Everything in one place
Instead of hunting for sample files, generate them live and download them. Handy for checklists before a release.
Checklist before go-live
Normal image, wrong extension, broken file, rotated phone photo, CMYK, and extreme sizes — note whether your system rejects or auto-fixes.
For automated tests
Download the files into your test pipeline so regressions stay visible even when encoders change.
FAQ
Are corrupted files dangerous?
No. They are intentionally truncated test data for parsers — not malware.
Where should I start?
With the image inspector and the corrupted image generator — then wrong extension and EXIF.
