UPDF - Free PDF Editor

The Best Free Nitro PDF Editor Alternative

The Nitro PDF editor and productivity suite is a pro-grade toolkit of PDF utilities with extensive features spanning nearly all essential PDF tasks. While the product itself is comparatively expensive, a lot of users are also disappointed by the fact that there's no Mac support under the Nitro banner itself. Mac support only comes from PDFpen and PDFPenPro, which was acquired in 2021 by Nitro for $6 million. But the product has a very different look and feel from Nitro products. Users can also take advantage of the Nitro PDF editor online but the features are highly limited if you're looking to use the online Nitro PDF editor free of charge.

UPDF: The Best Nitro PDF Editor Alternative

UPDF PDF editor

Supporting both operating systems, UPDF is self-styled as the world's first free premium PDF editor. "Free" because there's absolutely no subscription or license purchase needed, and "premium" because it matches the bulk of features offered by premium PDF editors like Nitro PDF Pro and Adobe Acrobat Pro DC. Moreover, it's fast and can handle large workloads with ease.

What are Some Key Features of UPDF?

  • PDF Editing - The primary goal of this free Nitro PDF editor alternative is to provide users with a seamless PDF editing experience no matter what content they want to add, remove, or modify. This includes images, embedded objects, text. If there's something on a PDF, you can edit it with UPDF.
  • PDF Security - Password-lock PDFs or prevent unauthorized modifications, copying, or printing.
  • Organize PDFs -Manage pages easily with remove, replace, rotate, copy, crop, delete, and other tools.
  • PDF Printing - Dedicated Print Dialog with customizable printing options to print PDFs exactly the way you want them, with full control over dimensions, layouts, and other attributes.

Why UPDF Over Nitro PDF Pro?

  • Similar arsenal of essential and advanced PDF tools.
  • Free vs $130 for PDFpenPro and $180 for Nitro PDF Pro.
  • Consistent experience across Windows and Mac - not the same with Nitro and PDFpen.
  • Intuitive interface with simple navigation - Nitro UI is a little more complex, as is the PDFpen for Mac interface.
  • PDF tools that match any premium PDF editor almost feature-for-feature, but totally free.

How to Perform OCR in the Nitro PDF Editor

Nitro PDF Pro comes with an advanced and highly accurate PDF OCR module with critical settings for color flattening, auto-detecting the orientation of the text, fixing the threshold, etc. The OCR process is simple, but you'll need to follow the steps shown here:

Step 1: Enable OCR in Nitro PDF Pro

When a document is open, bring your mouse to the Documents section and click OCR - you'll find it in the Review tab

You will also get a prompt when a scanned document is opened - click Use OCR when you see the prompt

In the OCR dialog, choose whether the conversion should be to just editable text or text that's both editable and searchable (for archival purposes)

Step 2: Perform OCR in Nitro PDF Pro

Choose a page range in the Options section or click Advanced to see more OCR Settings

Click OK to perform OCR and convert the file into an editable or editable/searchable PDF.

In Closing

There are certainly many things you can do with the Nitro PDF editor to up your productivity at work or while studying, of course, but why spend such a hefty sum when you can get the same functionality free of charge elsewhere. UPDF is chockful of features that most premium editors offer, but the real appeal is the UI and UX of the product, which learns from the mistakes of other PDF editors and builds on top of that for a frictionless PDF experience that's also fun!
