访问 PDFnoted 官网,点击「提取图片」工具入口;拖放或点击选择需处理的 PDF 文件。PDFnoted 支持最大 200MB 文件,无需注册即可使用。
PDFnoted 将自动解析 PDF 结构,识别所有嵌入图像(包括 JPEG、PNG、TIFF 等),并在网页端生成缩略图预览列表,支持按页码排序与点击放大查看。
勾选需要导出的图片(支持全选/反选/单页筛选),点击「下载为 ZIP」按钮;PDFnoted 会打包所有选中图片,保持原始尺寸与色彩信息,下载后解压即可使用。
Go to the PDFnoted website, click the 'Extract Images' tool; drag & drop or browse to select your PDF. PDFnoted supports files up to 200 MB — no sign-up required.
PDFnoted scans your PDF and detects all embedded images (JPEG, PNG, TIFF, etc.), displaying them as thumbnails with page numbers — click any to preview full size.
Check desired images (select all, invert, or filter by page), then click 'Download as ZIP'. PDFnoted exports them at original resolution and color fidelity — just unzip and use.
不能。PDFnoted 仅提取「嵌入式矢量/位图」图片(即作者插入的图片对象),不处理扫描生成的页面级图像。如需提取扫描件中的图,请先用 OCR 工具转为可编辑 PDF。
默认按「page_数字_object_序号」命名(如 page_3_object_2.png),确保来源清晰可追溯;ZIP 包内同时包含 CSV 映射表,记录每张图在 PDF 中的页码与位置。
当前版本支持单次上传一个 PDF,但可连续处理多个文件——上传完成下载后,直接上传下一个,界面自动重置,无需刷新页面。
No. PDFnoted only extracts embedded image objects (e.g., inserted JPEG/PNG). It does not process page-level raster scans. For scanned PDFs, run OCR first to generate an editable version.
Images are named as 'page_X_object_Y.png' (e.g., page_3_object_2.png); a CSV mapping file is included in the ZIP showing exact page number and placement context.
PDFnoted processes one PDF per session, but supports sequential batch handling: after downloading, simply upload the next PDF — the interface resets automatically, no reload needed.
