pdfren is a simple PDF compression tool that leverages Adobe's online PDF compression tool via automated browser via the chromedp package.
The tools I found on Github rely on running ghostscript via an exec call. I think its better to have everything bundled.
Adobe's compression options out of the box seem to ensure maximally readable PDFs, so this tool only allows compression within those bounds. Ghostscript-reliant programs seem to give too much freedom, sometimes resulting in over-compressed, blurry outputs.
Running pdfren looks like:
pdfren /path/to/my/file.pdf --compression medium --outFile compressed-file.pdfSee all flag options with the help flag:
pdfren --helpI've noticed occasional timeouts, so you may have to re-run the command on occasion. This could be due to flaws in my JS selectors, changes to the adobe compression site, or some other issue.
If you like the tool and want to improve it, please do! I enjoy writing little scraper tools like this and would be thrilled to hear your suggestions.
