@Mihai Volintiriu on my MacBook Pro, I have set Canva PNG @3.125, then with limit file size checked and set to 49900kb which resulted in a file of 37mb. Dimensions 9933 × 14043px and 300DPI. Canva 'canvas' size of A0 84.1cmx118.9cm. Whilst I would have liked to ensure the original size was downloaded, I'm assuming this will work with no loss in quality on an image printed on A0 size? I tried it a second time with a different image, Canva download settings the same as above but set Limit File Size to 52000kb which resulted in a file size of 49.9mb which also worked. If the limit is supposed to be 75mb it would be good to have this fixed as it seems most, if not all, of my A0 downloads without fiddling with 'Limit Size' in Canva would be over 50MB but under that max.

@Tom Beeston Hi Tom, please see my reply above to @Mihai Volintiriu where I've done some tests below the 50mb size. there definitely seems to be an issue with larger file sizes, but my tests under 50mb did upload. Hopefully you'll see the issue and can resolve so I can upload the full actual file size. Many thanks! :-)

Thanks, probably a good idea for them to ensure their documentation is kept in sync and up to date.

Apologies, I have come across further detail which explains the process.

I tried Gelato as well and the first order (a sample order to test their products) was doomed from the start. Even though I received the samples, they were both delayed from the originally specified time and the poster was cheap any anything. I will never use them... I too hope that PrintShrimp is better (and I think it likely is), but from day one I've not been able to upload a file!

Very good video, and a very good point about changing the border for different sizes when they don't scale. One thing I noticed that are extra steps that aren't required for parts of that explanation. If you are just changing the background colour in Canva you don't need to add an object to do that, just change the canvas background colour. Additionally, I find the process to create the relevant file sizes to be overly complicated. This diagram is overwhelming, so the takeaway is that you ONLY need to create X, Y, Z file sizes and then in your really great backend process it will automatically apply them to the relevant sizes that are correctly scaled downwards. It would be highly beneficial that this is part of the pdf document information (for me I don't need to know about how to use Etsy and keywords, I need the technical process for the images on your side of things.). In your upload page, I personally would restructure this to make it easier for people to see what the primary file sizes are to create which will then filter down to the remainder. When I first when into that screen I was scared I was going to have to create all of them, but this can be easily resolved with a bit of structure and an easy to follow dummy guide.
