Use ffmpeg for JPEG to TIFF conversion
Converting to TIFF
You can convert a JPEG to TIFF:
ffmpeg -i input.jpeg -pix_fmt rgba output.tiff
Or from a video:
ffmpeg -i input.mp4 -pix_fmt rgba out%05d.tiff
What's important is specifying the RGBA colorspace via -pix_fmt rgba
. Keeping the YUV 4:2:0 colorspace from video (-pix_fmt yuv420p
) would produce TIFF files that cannot be opened in most programs (even though the YCbCr* colorspace is allowed).
How to compress output
By default this produces uncompressed TIFF images. You can choose a different compression algorithm using the -compression_algo
option:
ffmpeg -i input.jpeg -pix_fmt rgb24 -compression_algo lzw output.tiff
Valid options are packbits
, raw
, lzw
and deflate
(see ffmpeg -h encoder=tiff
).
* YCbCr refers to what in video compression is usually known as YUV
