About this conversion
What happens
The first APP0 segment and complete JPEG structure are verified; orientation is applied and metadata is removed.
Limits
25 MiB input. 12 megapixels, 8,192 pixels per side, one still frame, and 50 MiB output.
Things to know
PNG avoids another lossy encode, but it cannot restore details already removed by JPEG compression and is often larger. JPEG files without a valid leading JFIF 1.00–1.02 marker, malformed scans, unsupported coding, or unsafe dimensions fail closed.
