⚡ 簡単な評価:
- 価格: Foxit starts at $129.99/year. UPDF starts at $39.99/year.
- 最適な用途: Foxit suits teams and businesses. UPDF suits solo users and students on a budget.
- 主な違い: Foxit adds eSign, team controls, and an SDK. UPDF adds mind maps and unlimited AI chat.
- 私たちのおすすめ: Foxit for most users. Its security, collaboration, and integrations go further.

The cheaper PDF editor is not always the weaker one.
UPDF costs about a third of what Foxit charges per year.
Yet both tools let you edit PDFs, run OCR, and chat with an AIアシスタント.
The real gap shows up when you share PDF files with a team.
That is where price stops being the main factor.

1. AIアシスタント
フォックスイット: The Foxit AI assistant summarizes files and answers questions about them. It also finds sensitive data so you can redact it. That redaction tool matters for legal and finance teams.

UPDF: The UPDF AI assistant lets you chat with PDFs without usage limits. It summarizes, translates, and explains complex pages. This deep AI integration is UPDF’s biggest strength.
2. PDF Editing
フォックスイット: You can edit text, image objects, and layout like a Word file. PDF creation is simple, from blank PDFs or HTML files. You can also delete PDF file pages or whole sections in a few clicks.

UPDF: UPDF lets you edit PDFs with text boxes, images, and links. It handles basic edits well. Some reviews note limits with advanced edits compared to other editors.
3. Reading, Annotation & Organization
フォックスイット: Foxit PDF Reader is free for viewing and markup. You can annotate PDF files with stamps, comments, and handwritten signatures. Advanced search scans full text across your PDF pages.

UPDF: You can annotate PDFs with highlights, sticky notes, and comments. You can also add shapes and add bookmarks for quick jumps. Tools to organize PDF pages let you split, merge, crop, and rearrange multiple PDF files.
4. 光学文字認識
フォックスイット: Foxit’s optical character recognition turns scanned text into digital text you can search. It also supports handwritten notes conversion. This helps you convert paper documents into searchable archives.
UPDF: UPDF’s OCR turns scanned documents into editable PDFs. Big OCR jobs can use more device resources on older laptops. A few reviews mention weak support when OCR misbehaves.
5. ファイル変換
フォックスイット: Foxit converts PDFs to and from Microsoft Office formats. Layout stays close to the original in Word output.

The PowerPoint converter works the same way for slide decks.

UPDF: UPDF can convert PDF files to Word, Excel, PPT, RTF, XML, HTML, and PNG. You can also extract text in one click. The range of formats is wide for the price.
6. Platforms & Mobile Apps
フォックスイット: Foxit supports Windows, Mac, and older Linux versions. Mobile apps run on Android and iOS. The PC version and desktop Mac app share the same core tools.

UPDF: UPDF is compatible with Windows, Mac, iOS, and Android. One license covers up to four devices on various platforms. That makes it simple to switch between operating systems.
7. Collaboration, eSign & Cloud
フォックスイット: Foxit PDF Editor Cloud allows real-time PDF collaboration in the browser. Foxit DMS unifies editing, signing, and cloud file storage in one secure hub. Checked out file handling stops other users from overwriting your edits.
UPDF: UPDF Cloud lets you access PDF files on every device. UPDF Sign adds signing for a separate fee. Team tools like shared reviews and file locking are limited.
⚠️ 警告: Foxit’s online reader only comes with a Foxit PDF Editor bundle. You can’t get browser access through the free reader alone.
8. セキュリティとデータプライバシー
フォックスイット: Foxit says it follows accepted standards for data protection. It is reported to be SOC2 compliant and supports Microsoft Information Protection. File protection tools include passwords, permissions, and redaction.
UPDF: UPDF offers password protection and encrypted cloud storage. It does not publish the same compliance badges as Foxit. Login problems are a common complaint, such as codes that never arrive by email.
9. Integrations & Developer Tools
フォックスイット: Foxit connects with Microsoft Teams, SharePoint, Google Workspace, and Salesforce. It also works with Google Drive and other popular cloud services. A PDF SDK lets developers build Foxit products into their own apps.

UPDF: UPDF focuses on its own cloud and apps. 仕事 integrations are thin. If you live inside SharePoint or Salesforce, this gap will matter.
