常見問題

Does this upload my PDF?

No. All processing happens locally in your browser using pdf-lib. Nothing is sent to any server.

Does this work on mobile?

Yes. Works in Safari on iPhone/iPad and Chrome on Android. Tap the upload area to select a PDF.

Is there a file size limit?

No imposed limit. The practical limit is your device memory. Most modern devices handle hundreds of megabytes.

Are password-protected PDFs supported?

No. Remove the password from the PDF first using your PDF reader, then use this tool.

What PDF versions are supported?

Standard PDF 1.x and 2.0 files. Encrypted PDFs are not supported.

Is the output quality the same as the input?

Yes. The tool does not re-encode page content. Text remains selectable and images retain full resolution.
