About upub.app and ShellNewHandler

In their own words, as submitted to SaaSHub.

ShellNewHandler

upub turns fixed PDF pages into real, reflowable EPUB text. Instead of shrinking a paper page onto a six-inch screen, it rebuilds the book: reading order, chapters, headings, footnotes and images. Running headers and page numbers are removed from the text flow. Scanned PDFs are supported through...

Overall verdict

  • ShellNewHandler is a niche, lightweight utility hosted on SourceForge designed to give users more control over the Windows 'New' context menu (the ShellNew menu). It can be considered good for its specific narrow use case, but it is an older, minimally maintained tool that may not suit all users, especially those on modern Windows versions.

Why this product is good

  • Provides direct control over customizing the Windows right-click 'New' menu, allowing users to add or remove file type entries
  • Lightweight and free, without bundled bloatware typical of some other free utilities
  • Simple and focused in scope, making it easy to understand for its specific purpose
  • Open distribution via SourceForge allows transparency and no-cost access

Recommended for

  • Power users who want to declutter or customize the Windows New context menu
  • IT administrators managing standardized desktop environments across multiple machines
  • Users comfortable with older utility-style tools and Windows registry-related tweaks
  • Not recommended for casual users seeking modern, actively supported software with regular updates

Questions & Answers

As answered by people managing upub.app and ShellNewHandler.

What makes your product unique?

upub.app's answer

  • Rebuilds the book, not just the file: reading order, chapters, headings, footnotes and images are reconstructed; running headers and page numbers are removed from the text flow.
  • Handles scanned PDFs: AI-assisted OCR turns page images into real, resizable text.
  • No silent errors: every page gets a confidence score, and uncertain pages are flagged in a downloadable quality report.
  • Device-aware output: 23 e-reader profiles, including native KEPUB for Kobo.

Why should a person choose your product over its competitors?

upub.app's answer

Most converters, online tools and even Calibre mostly extract characters and guess where paragraphs belong. With complex or scanned PDFs, the result is broken lines, page numbers inside sentences, or pages that stay as tiny images.

upub analyzes the page layout first, then packages a validated EPUB 3. It also tells you which pages it is unsure about, instead of hiding mistakes.

Pricing is pay once: credit packs from $4.99 for 1,000 pages, no subscription, and credits never expire.

How would you describe the primary audience of your product?

upub.app's answer

E-reader owners (Kindle, Kobo, PocketBook, Boox, reMarkable) who have books, papers or course material only as PDFs, including scans, and are tired of zooming and panning on a small screen. Students, researchers and avid readers in any language, including right-to-left and CJK scripts.

What's the story behind your product?

upub.app's answer

upub started as a tool for one reader. A close friend had many books only as PDFs made for A4 paper, and on her e-reader she had to zoom, drag sideways and find her line again after every move. Existing converters flattened the books into screenshots, dropped headings and scrambled footnotes. So I wrote her a converter that understood the layout and returned a real EPUB with her font, her size and chapters where chapters belong. She read three books that week and said: "Don't keep this to yourself." upub is that same tool, now for everyone stuck with a PDF.

Which are the primary technologies used for building your product?

upub.app's answer

Python, FastAPI, PostgreSQL, Google Gemini (layout analysis and OCR), pdftext and PDFium for PDF parsing, Next.js with Tailwind CSS for the web app, Docker, and Polar for payments. Output is validated with W3C EPUBCheck.

Who are some of the biggest customers of your product?

upub.app's answer

My Girlfriend :)

  • I recently got libreoffice, but now the new option in right click looks like a mess. Can someone help me get rid of them please?
    Use Shell New Handler. Run the portable app and simply untick the items you don't want to appear in your new context menu. Source: about 4 years ago
  • This menu should be easy to add/remove programs to... Who is really creating Access Databases from this menu often enough to keep it here? (Not me!) Is there an easy way to edit this?
    I've always used ShellNewHandler for this. It's a really simple portable utility that allows you to remove most of the items from that menu. Tested it out on Windows 11 and it's still compatible. Source: over 5 years ago
