Rescale Image to larger size

lingreon

Hi ~ I was wondering if I can scale a 300dpi 11x14 jpg to a larger size ~ to 16x20 and 24x36 without compromising image quality ~ don't want it being pixelated.
and what's the best way to go about it?
Currently using Gimp and Photopea.
Thanks!

Are you sure your numbers are correct? Image files have no inherent dpi; dpi refers to the dot pitch of the printer.

What you need is the number of pixels. I don't use either of those editors, but I assume you they will tell you the dimensions in pixels. If not, you can get it from Irfanview, a free and very useful image viewer.

So-called uprezzing--increasing the resolution to print larger--will compromise image quality, but that's not the question. The question is when it will damage quality enough that the print isn't good enough for you. That depends on the number of pixels and the quality of the printing software. For example, I have an 11 x 19 print made from an 8 megapixel file cropped from an original 12 megapixel camera, and it looks quite good, printed by Lightroom.
