title: Image Magick - trim and repage - loss of quality
body: <p>When I use this command to trim a PDF file:</p>
  
  <p><code>convert -fuzz 1% -trim +repage multi0.pdf multi0new.pdf</code></p>
  
  <p>The result is very disappointing and the trimmed image size becomes more than 10 times lower than the source.</p>
  
  <p>Is there any way to make a clean image trimming without loss of quality? </p>
  
  <p>(here it is, before and after)</p>
