Maipdf的PDF文件分享链接

Maipdf是一个提供安全PDF文件上传和分享的在线平台。通过Maipdf,您不仅可以方便地分享PDF文件,还可以通过设置一些权限来防止文件被复制、打印或下载。

以下是Maipdf平台的一些主要功能,帮助您确保文件的安全性和防止未经授权的复制:

如何生成分享链接

在Maipdf网站上,您可以轻松上传PDF文件并生成分享链接。上传过程简单,只需选择您要分享的文件并设置相关权限,然后生成一个唯一的分享链接。您可以将这个链接发送给指定的收件人,收件人点击链接后即可在线查看文件。

防止文件复制

为了保护您的PDF文件不被复制,Maipdf提供了强大的防复制功能。具体来说,Maipdf会对生成的文件链接进行加密,防止文件内容被复制到剪贴板。同时,您可以设置文件在浏览器中仅能被查看,禁止直接下载或打印。这些设置将帮助您确保文件内容不会轻易被非法传播。

限制有效打开次数

除了防止复制之外,Maipdf还允许您设置文件的有效打开次数。您可以设置文件的链接只能被查看特定次数,或者在特定时间内有效。一旦达到最大打开次数或过期时间,文件链接将无法继续访问,进一步增强了文件的安全性。

其他安全设置

From cloud link sharing to protected .maipdf files

The same MaiPDF product family supports two paths: fast Online Cloud Sharing for browser links, and MaiPDF App / App DRM for stronger file-level control. These App screens show how a PDF can move from upload to DRM packaging and protected viewing.

MaiPDF App cloud sharing flow

1. Create a cloud share

Use Online Cloud Sharing when you need a quick PDF link, QR code, password, expiry, and access records.

2. Package as .maipdf

For sensitive contracts, proposals, or internal files, use App DRM to create a protected .maipdf document.

3. Open in protected viewer

Recipients view the document under controlled conditions instead of receiving an ordinary uncontrolled PDF.

Use Online Cloud Sharing for speed; use MaiPDF App DRM when screenshots, forwarding, or device access matter

SendPDFOnline pages now describe MaiPDF as a two-level product family: Online Cloud Sharing creates quick browser links and QR codes, while the MaiPDF App creates protected .maipdf packages for sensitive PDFs that need App DRM controls.

Fast cloud link

Upload a PDF, share a browser link or QR code, and keep read code / modify code management.

Protected .maipdf file

Package the PDF in the MaiPDF App with local encryption, license rules, expiry, open limits, and revoke control.

App-only protections

Use protected viewer, device binding, screenshot-aware controls, watermark trace, and license management where supported.

No web page can fully stop screenshots. MaiPDF App DRM is positioned as the stronger path: reduce casual copying, bind access to identity/devices, revoke licenses, and trace leaks with visible watermark information.

Need stronger control?
