常見問題
Is JPG轉PDF free?
Yes. JPG轉PDF is completely free with no sign-up, no watermark and no daily limit. There is no paid tier — every tool on iAdorePDF is free to use as often as you like.
Is JPG轉PDF safe and private?
Yes. JPG轉PDF runs entirely inside your browser, so your file is never uploaded to any server. Nothing leaves your device, which makes it safe for confidential documents.
Do I need to install any software?
No. JPG轉PDF works in any modern browser — Chrome, Safari, Firefox or Edge. There is nothing to download and no account to create.
Does JPG轉PDF work on a phone?
Yes. JPG轉PDF is built mobile-first and works on iPhone and Android exactly as it does on a computer, straight from the browser.
Can I combine several photos into one PDF?
Yes. Select as many images as you like, arrange them in the order you want, then choose whether each page should fit the image or use a fixed A4 or Letter size.
How do I use JPG轉PDF?
Open the page, drop your file into the upload box (or tap Select file), choose your options, then press the start button. Your result downloads straight to your device.
Is there a file size limit?
There is no server limit because the work happens on your own device. The practical ceiling is your device memory; files up to about 100 MB are comfortable on most phones and much larger on a computer.
