BMP ndeimwe yemhando dzakakodzera dzekutora skrini uye kudhirowa?

Yeah, for exactly the reason it is the wrong one for photographs.

Nei BMP ichisaratidzwa mubrowser yangu?

Nekudaro, nekuti mabhurawuza anotora mukana wekuti zvinyorwa zvinyorwa zvive nezita rezita rezita, uye BMP iri kunze kweiyo - inoenderana ne scanning, print, kana editing workflow kupfuura pane web.

Mumwe chete chete. The pixels that were captured are all the detail there is: enlarging either interpolates, which softens edges, or uses an AI upscaler, which invents plausible detail that was never in the original. Both are fine for a step up of a third or so and neither turns a thumbnail into a poster. Start from the largest copy you have and resize down wherever the choice exists.
