常見問題
Is OCR辨識 free?
Yes. OCR辨識 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 OCR辨識 safe and private?
Yes. OCR辨識 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. OCR辨識 works in any modern browser — Chrome, Safari, Firefox or Edge. There is nothing to download and no account to create.
Does OCR辨識 work on a phone?
Yes. OCR辨識 is built mobile-first and works on iPhone and Android exactly as it does on a computer, straight from the browser.
Can it read text from a scanned document?
Yes. The OCR engine recognises text in scanned pages and photos in dozens of languages and gives you the text back as a file you can copy and search. It runs on your device, so scans of private paperwork stay private.
How do I use OCR辨識?
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.
