1. 步骤1:打开PDFnoted并选择‘图片转PDF’功能

访问 pdfnoted.com,点击首页「图片转PDF」按钮(或顶部导航栏对应选项)。页面自动加载轻量级Web应用,所有处理均在浏览器内完成,原始图片永不离开你的设备。

2. 步骤2:拖拽或批量上传图片,调整顺序与页面方向

直接拖拽JPG、PNG、WebP等格式图片到上传区,或点击选择文件(支持一次选中100+张)。上传后,PDFnoted自动预览缩略图,点击上下箭头可拖动排序;点击单张缩略图右上角旋转图标,可单独调整竖/横版方向。

3. 步骤3:设置PDF参数并生成下载

在右侧设置面板中,选择纸张尺寸(默认A4)、页边距(推荐‘紧凑’模式)、图像填充方式(‘适应’或‘居中’)。确认无误后点击「生成PDF」,PDFnoted即时合成并弹出下载对话框——文件名默认为‘images-to-pdf.pdf’,支持重命名保存。

1. Step 1: Open PDFnoted and select ‘Images to PDF’

Go to pdfnoted.com and click ‘Images to PDF’ on the homepage (or via top navigation). The lightweight web app loads instantly—processing happens entirely in your browser; your images never leave your device.

2. Step 2: Drag & drop images, then reorder and rotate

Drag & drop JPG, PNG, or WebP files—or select multiple (up to 100+) at once. Thumbnails appear instantly. Reorder by dragging thumbnails or using up/down arrows. Click the rotate icon (top-right of any thumbnail) to fix portrait/landscape orientation per image.

3. Step 3: Configure PDF settings and download

In the right sidebar, choose paper size (A4 default), margin (‘Compact’ recommended), and image fit mode (‘Fit’ or ‘Center’). Click ‘Generate PDF’—PDFnoted renders it locally in <2 seconds and triggers an instant download. Rename before saving; no sign-up required.

小贴士:✅ 小贴士:提前用系统画图工具裁剪白边,能让PDF更整洁;若图片比例差异大,选‘适应’模式可避免拉伸变形;导出前务必检查顺序——PDFnoted不自动按文件名排序。
Tips: ✅ Pro tip: Crop white borders in OS built-in Paint/Preview first for cleaner output. Use ‘Fit’ mode for mixed aspect ratios to prevent distortion. Always verify order—PDFnoted doesn’t auto-sort by filename.

常见问题

FAQ

PDFnoted会上传我的图片到服务器吗?

不会。PDFnoted采用纯前端技术,所有图片处理均在您的浏览器内存中完成,原始文件不经过任何网络传输,保障隐私与安全。

支持哪些图片格式?最大单张尺寸是多少?

支持JPG、JPEG、PNG、WebP和GIF(静态帧)。单张图片建议≤20MB(超大图可能影响渲染速度),总图片数建议≤150张以保证流畅体验。

生成的PDF能编辑文字或添加水印吗?

当前‘图片转PDF’功能输出的是不可编辑的图像型PDF(即每页为嵌入图片)。如需OCR识别文字或加水印,请使用PDFnoted的‘PDF编辑器’或‘PDF加水印’独立工具。

Does PDFnoted upload my images to a server?

No. PDFnoted runs 100% client-side—images are processed entirely in your browser memory. No data is uploaded, ensuring full privacy and zero server exposure.

Which image formats are supported? What’s the max file size?

Supports JPG, JPEG, PNG, WebP, and static GIF. Max per image: ~20 MB (larger files may slow rendering). For best performance, keep total count ≤150 images.

Can I edit text or add watermarks to the generated PDF?

The ‘Images to PDF’ output is a raster-based PDF (each page = embedded image), so text isn’t selectable. For OCR or watermarking, use PDFnoted’s separate ‘PDF Editor’ or ‘Add Watermark’ tools.
