Why doesn't Opencart handle high resolution images?

Question

opencart

I get the error Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 16728 bytes)
when processing an image with a resolution of ~4000x3000px, while the image weighs 400 kb. (lots of white background).
When the resolution is reduced, everything works out.
Is it possible to do without increasing php_memory_limit?
Opencart 3020 System, Standard Image Loader

Answer 2

without increasing php_memory_limit - you can use shell_exec. Use convert from ImageMagick

Answer 3

Without increasing, only rewrite the code, but increasing it is many times cheaper
