title: How to shrink/compress images in TiddlyWiki?
body: <p>I have few dozens of images in my TiddlyWiki. I use a one-file format, so the file grew to 30+Mb and the wiki started to lag when I save tiddlers. Most of my images are just screenshots and I believe they can be painlessly compressed 10x or more. How can I do it automatically or semi-automatically? I want to avoid the &quot;export, compress, import, update all the transclusions&quot; procedure.</p>
  <p>One way that I can imagine is exporting the wiki into a multi-file format, editing the images and assembling the wiki into the single file again, but maybe there's an easier way? Seems that there could be such tools for regular HTML files with embedded images, but I never worked with those and therefore ask for an advice.</p>
  <p>There's also an image editor integrated in TiddlyWiki, but it seems it's not capable of resizing images (its resize function actually does cropping).</p>
