Introducing PDF Engine v4: More Power, More Flexibility!

Hey friends! We’ve been working hard behind the scenes, and after a quite long but uneventful beta period… Meet the brand new PDFMonkey Engine v4!

What’s New?

Extended Generation Time

Depending on your plan, we’ve stretched the limits of generation time:

  • 🙂 Free: 30 seconds, no change
  • 😃 Pro: up to 2 minutes (also applies during the 14-day trial)
  • 😎 Pro+: up to 3 minutes
  • 🤯 Premium: up to 5 minutes!

A newer Chromium version

While engine v3 is running on Chromium v86, the new v4 runs on Chromium 116, bringing a bunch of improvements that’ll make your life easier:

  • ⚡️ CSS must-haves: Dive into the latest features like the :has() pseudo-class, container queries, text-wrap: balance, import maps, and the swift HTTP/3.
  • 🚀 Boosted Performance: With this new version we’ve seen some improvements in generation speed. We also stopped including the Emoji font by default, which avoids spending time on something the vast majority of templates doesn’t need.
  • 👌 Enhanced Page Format Adherence: While v3 uses rounded values from mm to inches for page size, for standard formats like A4 or Letter, v4 will use the proper page size.
  • 🪄 Magical Fixes: While providing customer support, we’ve seen that migrating from v3 to v4 mysteriously fixed some lingering issues. We don’t have a wizard on staff (yet), but we’re glad it works!

A Few Caveats to Note

  • Emoji Alert: If you need Emojis in your template, you will need to toggle the option in your template’s settings once you’ve migrated to v4.
  • Tiny Page Format Tweaks: There’s a slight change in dimensions—for instance, A4 has gone from 793×1120 to 794×1122 pixels. You might need to nudge your templates a bit, which you can easily do in the template editor.

Smooth Migration Path

Switching over is a breeze with our template editor’s engine selection feature. You can test drive v4 without affecting your live setup. Remember, your templates stick with v3 until you decide to publish with v4.

We’re Here for You!

Happy generating!
