Advanced PDF Suite FAQ
How do I merge PDF files into one?
Choose Merge PDFs and add two or more PDFs. Drag them into the order you want (you can also rotate or duplicate a file), then press Merge PDFs to download one combined PDF.
Are my PDF files uploaded to a server?
No. The tools run in your browser, so your files stay on your device. OCR downloads its engine and language data from the jsDelivr CDN the first time (your PDF is not sent), and the optional Ask AI tool sends the document's text and your question to OpenAI or Anthropic, using your own API key, only when you ask something.
Can I convert a PDF to Word?
Yes. PDF → Word saves the text as an editable .docx, but only the text: layout, images and fonts are not kept. A scanned PDF has no text to copy, so use OCR scan instead, which reads English, Hindi, Spanish, French or German and saves the text as a .txt file.
How do I convert JPG images to PDF?
Choose Images → PDF, add PNG or JPEG images and drag them into order. Each image becomes one page at its own size, phone photos stay upright, and Create PDF downloads a single PDF.
Can I reduce the size of a PDF?
Partly. Optimize PDF removes unused data and repacks the file without touching quality, but it does not recompress images, so scanned and photo-heavy PDFs may shrink little; if the result is not smaller, you get your original back. The PDF Compressor in the Universal Conversion Suite recompresses the JPEG photos inside a PDF and can aim for a size in MB.
How do I sign a PDF online?
Choose Sign (eSign), draw your signature with a mouse, pen or finger or type your name, then click or drag to place it on a page and set its size before you download the signed PDF. This adds an image of your signature, not a certificate-based digital signature.
