PDF Tools
Merge two or more PDF files into one document — no upload, no sign-up, the whole job runs locally in your browser.
PDF 合併工具Merge two or more PDF files into one document — pages keep their original size and quality, the order follows your selection, and everything runs in your browser: no upload, no sign-up, nothing ever leaves your machine.圖片 to PDF 轉換器Convert JPG and PNG images into a single PDF in your browser — every photo becomes a page in the order you picked them, original resolution is kept, and nothing is uploaded: no account, no queue, no size games.Photo to PDF 掃描器Turn phone photos into a clean scanned-style A4 PDF — up to 30 images are centered and fitted onto uniform pages automatically, and the whole scan runs locally like a scanner app without ever uploading a photo.PDFRotatorRotate PDF pages in your browser — turn every page, or just the ones you name (like 1,3-5), 90° either way or upside down, with no re-encoding, no upload and no sign-up. Password-protected PDFs are not supported.反轉 PDFPagesFlip a PDF end to end — the last page becomes page 1 and vice versa, no page content is re-encoded, and the whole reorder runs locally in your browser with no upload and no sign-up.PDF to 文字轉換器Convert a PDF to text in your browser — every page is parsed locally with pdf.js, lines come out in reading order, and you get word and character counts plus a .txt download. No upload, no sign-up; scans (no OCR) and password-protected files are declined, and layout is not preserved.Extract 文字 fromPDFExtract the text out of a PDF in one tab: click or drop your file and pdf.js pulls every selectable line locally — the document itself never leaves your machine. Per-page failures degrade to a placeholder instead of killing the run.PDF 文字擷取器A local PDF text extractor: open the file with the pdf.js engine right in this page, copy the plain text or download it as .txt, with page/word/character counts shown up front. Image-only scans and encrypted files are declined up front — this tool is honest about what it reads.PDF to 單字轉換器Convert a PDF to a Word (.docx) file in your browser: pdf.js reads the selectable text, then a minimal reflowed Word document is assembled paragraph by paragraph — counts up front, copy and download included, no upload and no sign-up. Fonts, images and page layout from the original are not carried across (this is an honest text rebuild), scans get no OCR, and password-protected PDFs are declined.PDF to DOCX 轉換器Turn a PDF into a .docx you can keep editing: the text is extracted locally with the same pdf.js engine as our PDF text tools and rebuilt as clean Word paragraphs with the same builder as our Text to Word page. Reflowed plain text on purpose — not a pixel-faithful conversion; dense scans (no OCR), encrypted files and documents past the size gates are declined honestly, and nothing is ever uploaded.
