QuickPDF — the complete PDF toolkit, signing, and AI chat, all in one app. QuickPDF brings the PDF tools you usually need a desktop for straight to your phone. Merge, compress, split, rotate, and reorder pages. Sign documents, add watermarks and page numbers, lock or unlock with a password, and convert to and from Word, Excel, and HTML. Most everyday tools run right on your device — no upload, no account, no waiting. What QuickPDF does • Merge — combine multiple PDFs into one in the order you choose. • Compress — shrink file size for easier sharing and email. • Split — extract pages or break a big PDF into smaller ones with a visual page picker. • Rotate & Reorder — fix orientation and rearrange pages with a tap. • Lock / Unlock — add or remove password protection. • Sign PDF — draw or place your signature anywhere on the page. • Image to PDF / PDF to Image — turn photos into a PDF, or export pages as images. • Watermark — stamp text or image watermarks across your document. • Page Numbers — add automatic page numbering. • Annotate — highlight, draw, and mark up your PDFs. • Scanned Look — give a clean PDF the look of a scanned document. • OCR — extract text from images and scanned pages on-device with Google ML Kit. • Convert — PDF to/from Word, Excel, and HTML. • AI Chat with your PDF — ask questions about a document and get answers, powered by Google Gemini.
