Hi guys, has anyone got any good recommendations or advice on creating good free poster mockups (and quickly too - minimal photoshop etc. if possible)? I'm currently using a few off Canva and a few off Placeit, but the free options are a bit limited and I'm not the biggest fan of them! I like using the ones where the poster actually gets put into the mockup so its 3D with shadows etc. - not sure what you call them! Thanks :)

Hi! I've recently started designing posters on Canva, with some using raster graphics - and I am a bit stuck trying to work out what A size (A5 - A0) the graphics would start to be noticeably pixelated. If anyone has any advice/ experience with using these it would be reallyy appreciated. A lot of my designs use quite big graphics (as in they fill up a lot of the page), so I am worried about the print quality for the bigger poster sizes. FYI I'm using custom size pages of 4961 x 7016 px and with the PDF print export if that helps. Thank you!
