专为所有人打造的免费私人文档工具
JPG2PDF转换器的使命是让转换和编辑文档变得轻松、安全且完全免费。
We believe the tools you use every day to handle your documents should be fast, private, and free — without forcing you to upload sensitive files, create an account, or pay a subscription.
Why we built this
JPG2PDF转换器于2026年由Ahtisham ul haq Khan在经历了一次简单的挫折后启动：大多数“免费”在线PDF转换器要求您将私人文件上传到未知服务器，在队列中等待，然后添加水印或推送付费计划。
现代浏览器可以完全在您自己的设备上处理图像和构建PDF ，无需上传。因此，此网站上的每个工具都是这样工作的：您的文件与您同在，转换从您单击的那一刻开始，无需支付任何费用。
该网站由其创始人建造和维护。如果某个工具在您的设备或浏览器上不起作用，请通过联系页面发送详细信息，我们将对其进行查看和修复。
Our core values
Privacy First
We built our tools to run entirely in your browser. Your files are never uploaded, stored, or seen by us — privacy isn't a feature, it's the foundation.
Quality & Accuracy
Every conversion is engineered to preserve your original image quality, resolution, and layout so your PDFs always look professional.
Free & Accessible
Powerful document tools shouldn't be locked behind paywalls. Our converters are free for everyone, on every device, with no limits.
Transparency
No hidden tracking, no surprise charges, no fine print. We're upfront about exactly how our tools work and what happens to your data.
Built on trust and transparency
We hold ourselves to a high standard. Here's what that means in practice — and what you can always count on when you use any tool on JPG2PDF Converters.
- All processing happens locally in your browser — files never reach a server
- No account, email, or personal information is ever required
- No watermarks are added to any of your documents
- Tools are maintained and updated regularly for security and reliability
- A clear Privacy Policy, Terms of Service, and Disclaimer are always available
Conversion that happens on your device
When you select an image, your browser reads the file directly from your device into memory. Our converter uses well-established, open client-side libraries to render that image onto a PDF page and package it for download — all without a single byte being sent over the internet. Because there's no upload and no server round-trip, conversions are instant and your data is never exposed.
What each tool is built with
- JPG to PDF and PNG to PDF
- Images are read in your browser and placed on PDF pages with jsPDF, an open-source PDF library.
- PDF to JPG
- Pages are drawn with PDF.js, the open-source PDF renderer Mozilla built for Firefox, then saved as JPG.
- Document Editor
- Text is edited with Tiptap, an open-source editor. Saving as PDF uses your browser's print dialog.
Known limits
- Password-protected PDFs cannot be converted until the password is removed.
- HEIC photos from an iPhone open in Safari only. Other browsers need them saved as JPG first.
- Very large batches depend on your device's memory, because nothing is processed on a server.
- The Document Editor saves PDFs through the print dialog, so choose Save as PDF as the printer.
