Thanks for telling about the 18mpx limit, I've checked, it does work better with that type of pictures! I was converting bigger pictures in batches, that could have been the reason behind my issues.

Thanks, I've given it a try, and yes, even 100+mb .pngs work if the hardware behind that can handle it.

Thanks for the advice, I'll go check these out at the local electronics store!

This, the drives can't simply transmit info fast enough to give the CPU an actual workload.
By the way, what would be a way to get faster data transmission from an outer drive to the computer? That data speed bottleneck is often a problem for me...

Couldn't it be linked to the size of the .png file? If it's really huge, it could cause issues.

Yeah, that would actually be great, but I don't see how this could be doable with the technology that exists today, unfortunately...

Yes, it sometimes happens to me as well! It really needs a ton of .tiff files to be converted at once, but it sometimes happen.
I just thought it was a hardware limitation and just converted a bigger number of smaller batches, but if there was a way around it, it'd be great.

Thanks, I somehow missed this feature and spent a lot of time manually cropping everything... this is going to save me a lot of time, thanks! I'll stay tuned to hear what comes out of that idea to develop the auto-crop function further.
