從 PDF 擷取圖片
將每張內嵌照片擷取成個別檔案。
運作方式
上傳您的 PDF 並下載結果——每張內嵌的 JPEG 圖片都會擷取成個別檔案，若超過一張則會打包成 ZIP。
這個工具能擷取哪些圖片格式？
它能可靠地擷取 JPEG 圖片，這是掃描檔與照片較多的 PDF 中最常見的內嵌格式。以其他內部格式儲存的圖片可能無法擷取——屬於盡力而為，無法保證成功。
如果 PDF 沒有可擷取的圖片怎麼辦？
您會看到找不到圖片的訊息——這可能發生在純文字 PDF，或圖片格式是此工具無法解碼的 PDF 上。
Does this extract vector graphics or just photos?
Just embedded raster (JPEG) images — vector graphics like drawn shapes or icons aren't image files inside the PDF, so they're not extracted.
What resolution will the extracted images be?
Whatever resolution they were embedded at originally — this tool pulls out the actual image data, it doesn't downscale or recompress it.
Can I extract images from just a few specific pages?
The tool scans the whole PDF, but you choose which of the found images to actually download.
Is my PDF uploaded to extract the images?
No — extraction happens entirely in your browser. Your PDF and the images pulled out of it never leave your device.
Does this extract PNG images from a PDF?
No — only JPEG images. PNGs and other non-JPEG formats are compressed differently inside a PDF, and this tool doesn't decode those yet — if a PDF's photos are stored as PNG rather than JPEG, they won't show up in your results.
Is there a file size or page limit?
No hard limit from the tool — it runs on your own device instead of a server with an upload cap. A PDF with hundreds of pages or a lot of large photos will just take longer and use more of your browser's memory.
