RAW to JPEG

is possible save 15-20mb raw file 25mb or more jpeg?

since both raw , jpeg file size can dependent on image content , choices in compression settings there no easy, direct answer.  question doesn't seem make sense.

 

somehow suspect you've been given instructions create 25 mb file.

 

keep in mind there's old school of terminology where, in days of uncompressed tiffs, people in industry used shorthand describing how many pixels in digital image multiplying horizontal pixel count x vertical pixel count x 3 bytes per pixel , coming single number.  then, film scan 8 bits/channel saved uncompressed tiff take many megabytes on disk.

 

so, example, "25 megabyte" file requirement might mean need supply high quality image of 3600 x 2400 pixels.

 

later, term evolved "megapixels", more explicit since images stored in different formats, can have 6 or 12 bytes per pixel or more, , can embody compression.  shops still use "megabytes" in old school sense.

 

it's not uncommon people confuse old school "megabytes" term number of megabytes file takes on disk, though 2 can have nothing 1 another.
