立即使用提取图片 → Use Extract Images →

1. 上传含产品图的PDF文件

打开 PDFnoted 官网，点击「提取图片 / Extract Images」功能入口；拖拽或选择你的产品手册PDF（如品牌产品目录、报价单），PDFnoted会自动解析所有嵌入图像（包括矢量图转位图）。

2. 预览并筛选目标产品图

PDFnoted自动生成缩略图网格，按页面顺序排列；鼠标悬停可查看尺寸与格式（JPG/PNG），勾选需导出的产品图（支持全选/反选/按页筛选），避免导出水印或图标等非主体内容。

3. 一键批量下载高清图片

点击「批量导出」按钮，PDFnoted将按原始嵌入质量打包为ZIP压缩包（含命名逻辑：PageX_ImageY.jpg）；解压后即可直接用于详情页、PPT或ERP系统，无需二次裁剪。

1. Upload Your Product Catalog PDF

Go to PDFnoted.com, click ‘Extract Images’. Drag & drop or select your product catalog PDF (e.g., brand brochure or quotation sheet). PDFnoted instantly scans and identifies all embedded images—including vector graphics converted to high-fidelity raster.

2. Preview & Select Target Product Images

PDFnoted displays a thumbnail grid sorted by page order. Hover to check resolution and format (JPG/PNG). Select only product photos—use ‘Select All’, ‘Invert’, or ‘Filter by Page’ to skip logos, watermarks, or UI icons.

3. Download High-Res Images in One Click

Click ‘Batch Export’ — PDFnoted packages all selected images into a ZIP file, named logically (e.g., Page3_Image2.jpg), preserving original DPI and color profile. Unzip and use instantly in Shopify listings, PowerPoint decks, or ERP uploads—zero post-processing needed.

小贴士：✅ 提前重命名PDF为‘品牌_型号_日期.pdf’便于归档；✅ 导出前关闭PDF中的‘压缩图像’选项（Acrobat设置）以保真；✅ 首次使用建议试传1页PDF验证图像完整性。

Tips: ✅ Rename PDF as ‘Brand_Model_Date.pdf’ before upload for easy archiving; ✅ Disable ‘Compress Images’ in Acrobat preferences pre-upload to retain fidelity; ✅ Test with a 1-page PDF first to verify extraction accuracy.

常见问题

FAQ

PDFnoted能提取扫描版PDF里的图片吗？

不能。PDFnoted仅提取PDF中‘嵌入式图像对象’（如矢量图、插入的JPG/PNG），不支持OCR识别扫描件中的图片。请先用OCR工具转换为可编辑PDF再使用。

导出的图片是否保留透明背景？

是的。若原PDF中图片为PNG格式且含Alpha通道，PDFnoted会原样导出带透明背景的PNG；JPG则自动转为白底，确保兼容性。

单次最多可处理多少页的PDF？

免费版支持单文件≤200页、总图数≤500张；超限文件建议分批上传。企业用户可联系PDFnoted开通API批量处理权限。

Can PDFnoted extract images from scanned PDFs?

No. PDFnoted extracts only native embedded image objects (e.g., inserted JPG/PNG, vector graphics), not rasterized scans. For scanned PDFs, first convert to searchable PDF via OCR tools, then use PDFnoted.

Are transparent backgrounds preserved in exported images?

Yes. PNG images with Alpha channels in the source PDF are exported as transparent PNGs. JPGs default to white background for universal compatibility—no manual editing required.

What’s the maximum PDF page limit per upload?

Free tier supports up to 200 pages or 500 embedded images per PDF. For larger files, split uploads manually—or contact PDFnoted for API-based bulk processing (enterprise plans available).
