PDF 轉 JPG
將 PDF 的每一頁轉換成獨立的 JPG 圖片。
運作方式
上傳一份 PDF，每一頁都會轉換成個別的 JPG 圖片，可以單獨下載，也可以打包成 ZIP 一起下載。
JPG 圖片的解析度是多少？
頁面會以約 288 DPI 的解析度轉換——足夠清晰，可用於列印或放大檢視，而非低解析度縮圖。
我可以只轉換特定頁面，而不是整份 PDF 嗎？
每一頁都會轉換成個別的 JPG，但您可以選擇要保留哪些——只下載您需要的頁面即可。
Can I convert a password-protected PDF?
Not directly — you'll need to remove the password first using a PDF reader that supports it, then convert the unlocked file.
Does this work on mobile?
Yes — it runs in any modern mobile browser on iOS or Android, no app install needed.
Will the JPGs be numbered in page order?
Yes — each image is named to match its page number, so they stay in order when downloaded or zipped.
Is my PDF uploaded anywhere to convert it?
No — the conversion runs entirely in your browser using pdf.js. Your PDF and the JPGs it produces never leave your device or touch a server.
Can I get PNG instead of JPG?
No — output here is JPG only. It keeps files small and works everywhere, which covers most conversions. If you specifically need lossless PNG, this isn't the tool for it.
Does this extract the images inside my PDF, or convert whole pages?

Can I choose the JPG quality or make smaller files?
Not right now — every page renders at a fixed high quality (about 288 DPI), so there's no slider to trade quality for a smaller file. It means you don't have to guess at settings, but you also can't dial it down if you want tinier files.
How do I turn the JPGs back into a PDF?
