Truncated JPG image for testing (corrupted)

A damaged JPEG: the first half of a valid 800 × 600 image. The header states the full dimensions, but the picture data stops half-way, with no end-of-image marker.

This file is invalid on purpose. The file ends half-way through its compressed picture data, without the end-of-image (FF D9) marker.

Why test with this file

Tests image pipelines against a partial upload. Browsers draw the top of the picture and fill the rest with grey, while stricter decoders refuse the file, so different parts of one system can disagree about it.

Damage	Truncated to 50% of its length
Dimensions in header	800 × 600 px
Signature (FF D8 FF)	Present
End-of-image marker (FF D9)	Missing
Lenient decoders	Show the upper part of the image
Strict decoders	Report a truncated or premature end of file

What to check

After your application has processed sample-jpg-truncated.jpg, confirm that:

The upload is rejected, or the image is marked as damaged, rather than a half-grey thumbnail being published.
Reading the dimensions alone succeeds (800 × 600), which is why a header check is not enough to accept an image.
A resize or conversion job fails with a handled error and does not retry forever.

First bytes of the file

The first 64 bytes of sample-jpg-truncated.jpg as a hex dump: offset, bytes, then the same bytes as text. The JPG signature is FF D8 FF.

Damaged on purpose, and otherwise harmless: the file holds the same generated content as the valid samples. As with any download, scan the file with your own security tools before opening it. How files are made and checked

Download from the command line and verify

Fetch the file with curl, then compare its checksum with the SHA-256 value above.

curl -o sample-jpg-truncated.jpg 'https://sampletestfiles.com/downloads/samples/sample-jpg-truncated.jpg'
sha256sum sample-jpg-truncated.jpg     # Linux
shasum -a 256 sample-jpg-truncated.jpg # macOS

On Windows, run Get-FileHash sample-jpg-truncated.jpg -Algorithm SHA256 in PowerShell. A matching value proves that the download is complete and unaltered.
