Comment on PDFium: Chrome’s PDF rendering engine is now open-source

Comments

This is great because it is now the best open-source PDF rendering library. GhostScript, Poppler, XPdf, pdf.js -- they all sort of work alright, but are pathetic compared to FoxIt, on which this source code is based. What we now have with this source is a high performance highly compliant clean codebase of C++ PDF rendering code. Excellent news. Expect lots of future PDF innovations to be based on this.

I've had by far the best performance with Sumatra, which is open source but unfortunately Windows-only. I try Chrome's PDF reader once every few months, hoping it'll improve, but I always disable it when I see it's still disappointingly sluggish.

Sumatra just uses muPDF, FWIW.

I use ghostscript consistently more than ten years. No serious issues. I use it to read/print pdfs/pss from arxiv org. Last six years I also use sumatra. Faster but I prefer mupdf reader.
