PNG test files, any size.
Set a size and generate a structurally valid PNG immediately. Nothing is uploaded and nothing is stored.
PNG, built to spec.
Each file is a real truecolour PNG with a gradient, not a placeholder rectangle. The size you ask for is reached with a tEXt metadata chunk with a valid CRC, which decoders skip, so the result opens in Preview, Photoshop, browsers and Pillow. Most people generate these for checking image upload limits, CDN behaviour and thumbnail pipelines.

Questions.
How small can a PNG file be?
About 288 bytes. Below that the format cannot carry its mandatory structure, let alone padding.
Will the file open normally?
Yes — it opens in Preview, Photoshop, browsers and Pillow, because the padding lives in a tEXt metadata chunk with a valid CRC, which decoders skip.
Can I ask for an unusual size?
Any byte count above the minimum works, including values like 3,145,728 or 27.5 MB. Drag the caliper or type the number.
