Converting PNG to JPG via `imagemagick`
Describe the bug
I made a previous bug report indicating that converting a PNG into a JPG worked completely fine (#320), but when going back, I found a problem with this, too. After I upload a PNG and it gets successfully converted with imagemagick, I go to download it, but I'm unable to do so. For some reason, imagemagick breaks the images into several files such as image-name-0.jpg and image-name-18.jpg. So when trying to download image-name.jpg, it fails. This is not the case when using something like ffmpeg.

To Reproduce Steps to reproduce the behavior:
- Upload a PNG for conversion.
- Select conversion to JPG using
imagemagick - Initiate conversion.
- Wait for the conversion to finish.
- Try to download the image.
- See in the download tab of your browser, say something like "Site wasn't available", meaning it couldn't download the image.
- You can also then look at the
./datadirectory where the conversion took place, and see that the files were broken into several ones.

EDIT:
After some additional testing, I wonder if it's because of the file size I'm uploading for conversion. The particular file is about 30 MB. Anything, at least from the small set of images I tested, that was around 3-4 MB and below worked completely fine.
It does seem to work with vips, specifically with jpeg and jp2. Didn't try the other ones.
I followed the same steps and uploaded the .png file over 30MB, and it converted perfectly to .JPG. Attached a
Screenshot of the completion.
