访问 PDFnoted 官网 → 点击「Extract Images」工具入口 → 拖放或点击选择需处理的 PDF 文件(支持最大 100MB)。PDFnoted 自动解析文档结构,识别所有嵌入式图像(含矢量图转位图)。
PDFnoted 列出每张提取的图片缩略图,显示页码、尺寸与格式(如 JPEG/PNG)。点击任意缩略图可查看原图细节;勾选需要导出的图片(支持全选/反选),也可按页码范围快速过滤。
点击「Download Selected」→ 选择导出格式(PNG 保透明背景与无损质量,JPEG 更小体积适合网页使用)→ 单次下载 ZIP 压缩包,内含所有选中图片,命名含原始页码(如 p05_img02.png),便于后续管理。
Go to PDFnoted.com → Navigate to ‘Extract Images’ → Drag & drop or select your PDF (up to 100MB). PDFnoted instantly scans the file and detects all embedded images—including vector graphics rendered as high-res bitmaps.
PDFnoted displays thumbnails of all extracted images with page number, dimensions, and format (e.g., JPEG/PNG). Click any thumbnail to preview full resolution. Select individual images—or use ‘Select All’/‘Invert Selection’—and filter by page range for efficient curation.
Click ‘Download Selected’ → Choose PNG (lossless, preserves transparency) or JPEG (smaller size, web-friendly) → Get a ZIP archive containing all selected images, auto-named with source page (e.g., p05_img02.png) for instant organization.
是的。PDFnoted 直接解码 PDF 嵌入的原始图像数据(非截图),保留原始 DPI 和色彩信息;矢量图会按页面实际渲染分辨率导出,通常达 300+ DPI。
不能。PDFnoted 仅提取「嵌入式图像对象」,不处理 OCR 生成的整页位图。若 PDF 是扫描件(每页为一张大图),请先用 OCR 工具分离插图区域,再上传到 PDFnoted。
没有。PDFnoted 不添加任何水印、版权标记或使用限制;导出图片完全归你所有,可用于编辑、印刷或商业项目。
Yes. PDFnoted decodes embedded image data directly—not via screenshot—preserving original DPI, color depth, and metadata. Vector graphics are rasterized at actual render resolution (often ≥300 DPI).
No. PDFnoted extracts only native embedded image objects—not full-page scans. For scanned PDFs (where each page is one bitmap), use OCR tools first to isolate illustration areas, then upload the cleaned PDF.
None. PDFnoted adds no watermark, copyright tag, or usage restriction—exported images are yours to edit, print, or use commercially without limitation.
