What is a 50MB PNG file useful for?
A 50 MB PNG is an infrastructure limit-testing file representing a very high-resolution lossless asset — a large-format print file, a scanned technical drawing, or a stitched panoramic image. Use it to verify that your application rejects the upload before decoding (preventing a ~300 MB RAM spike), that the rejection is clean with no orphaned temp files, and that your S3 or R2 multipart upload configuration handles large object writes correctly.
What's inside this file?
Generated with Pillow in RGBA mode. Approximately 10,000 × 7,500 pixels. The uncompressed RGBA raster is approximately 300 MB. PNG's DEFLATE achieves a 6:1 ratio on synthetic gradient content. Decoding this file with Pillow loads the full 300 MB raster into RAM — use this to test OOM handling in image processing workers before it happens in production.
