This doesn’t work with the url: I just encountered a similar issue. Questions Why is this a problem?
How to Convert a PDF to JPEG using PHP
Each page is essentially a big image. So I figured out I needed to encode the url properly. It always works fine for the first 10 images, but starting at index X and thereafter it always gets an exception. Post as a guest Name.
PHP Method Imagick::readImage Code Examples
Do you have access to PHP execso that you could run the command line and see if that fails? I solved it by encoding it correctly, but the answer marked as correct is a much better solution.
It seems that when you are reading a page that is far enough into the PDF file, it gets the exception. I guess what I should do in that case is to break up every part of the url and encode all different parts in some way.
Victor Bocharsky 6, 5 35 With an imagemagick object whose data was created from this function, I could scale, change the colors, and perform artistic effects upon the object, without any problems at all, but then there was a problem with saving: I’m not sure if this code is optimal, but it works. ReadImage takes a string containing the folder location of the file, and ReadImageFile takes a rfadimage pointing to the file location.

I’m trying to extract pages 0 to It always gives an exception in the readImage command when index is around 15 or higher depending on the source PDF.
As described in my answer: I tried the same test on another hosting account with PHP 7. Read page 1 from test. ImagickException Unable to read the file: If it still fails try reading 5 pages at a time which will hopefully isolate the problem. Got a patch for a bug? The functions setImageFormat and setFormat, programmed line after line, provided no effect to changing the format to png, bmp, or gif. Based by looking at the pages, you would think that they behave the exact same, except in their arguments: Include the ImageMagick version, OS, and any command-line required to reproduce the problem.
The problem is that Imagick can’t handle the uri format. They all fail on the readImage[X] command. Select all convert bound. Try to use urlencode function for encode special chars of url: The imagiick page is  and you are requesting page  which would be the 16 page.
