Password-protected PDFs are not supported.การกลับด้าน 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.ตัวแปลง PDF to ข้อความConvert 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 ข้อความ 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.ตัวแยก PDF ข้อความA 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.ตัวแปลง PDF to คำConvert 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.ตัวแปลง PDF to DOCXTurn 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.
