最佳的免費(fèi)PDF編輯器取決於你的需求。對於簡單的瀏覽器端編輯，PDFescape支持文本編輯、繪圖和添加鏈接，且無需安裝，但文件不超過10MB；若需更多功能，LibreOffice和WPS Office提供桌面應(yīng)用，可進(jìn)行基本編輯和註釋，適合個(gè)人使用；移動(dòng)設(shè)備用戶可選用Xodo PDF，具備文本編輯、簽名和高亮功能，並支持云同步；但需注意常見限制，如文件大小、水印、缺乏OCR及雲(yún)存儲(chǔ)空間有限等，敏感文檔應(yīng)避免上傳至不明服務(wù)。

The best free PDF editor depends on what you need to do. If you're looking for something simple and browser-based, there are several tools that let you edit text, add comments, highlight, and even rearrange pages without paying a dime. But if you want more advanced features like OCR or form creation, you might need to look at desktop apps or weigh the pros and cons of freemium models.

1. Light Editing in Your Browser: PDFescape

If you just need to make small changes—like adding text, drawing shapes, or inserting links— PDFescape is one of the most reliable free online editors.

• It works directly in your browser, no install needed
• You can edit text and images (within limits)
• Free version supports files up to 10MB

One thing to note: it doesn't support editing scanned PDFs unless you upload a searchable PDF. So if your document is a scanned image, you'll need OCR software first.

2. More Features with LibreOffice or WPS Office

If you're okay installing a desktop app, both LibreOffice and WPS Office allow basic PDF editing after importing the file.

• LibreOffice converts PDFs into editable documents but formatting may shift
• WPS has a built-in PDF editor with markup tools, simple text editing, and annotation
• Both are free for personal use

These aren't full-featured PDF editors like Adobe Acrobat, but they're good enough for casual edits and offer more flexibility than many browser tools.

3. Mobile-Friendly Option: Xodo PDF

For those who often work on phones or tablets, Xodo PDF offers a clean mobile app with solid editing capabilities.

• Edit text, add signatures, highlight and annotate
• Sync across devices via cloud
• Completely free, though with ads

It's especially handy when you're out and about and need to quickly mark up a document or sign a PDF.

4. Watch Out for Common Limitations

Free PDF editors usually come with some restrictions:

• File size limits (often under 15MB)
• Watermarks on edited/exported files
• No OCR or form creation in free tiers
• Limited cloud storage

Also, if you're handling sensitive documents, avoid uploading them to unknown online services. Stick to well-known tools like PDFescape or Xodo, which have clear privacy policies.

So, depending on how much you need to do, you've got options. For quick fixes, go with PDFescape. Need more flexibility? Try WPS or LibreOffice. On the go? Xodo's got you covered. Just keep in mind the usual free-tier caveats—and don't upload confidential docs to sketchy sites.基本上就這些。
