About and limitations
The 85 mm and 180 mm presets are typical starting values, not journal requirements; always check the target journal. Input is capped at 25 MB and output at 80 megapixels. Browser canvas resampling may soften line art, JPEG is lossy, and increasing dimensions cannot create missing detail. Very large images may exceed device memory. See methods.
