LocalPDF Toolkit

100% local PDF tools - merge, split, compress, sign, watermark. No upload, no server, your files never leave your browser.

100% local processing — your files never leave your computer. LocalPDF Toolkit runs entirely inside your browser with a built-in PDF engine. Unlike online PDF converters, we have no servers, no uploads and no accounts. Your contracts, invoices, IDs and business documents are processed on your device and stay on your device — that's real privacy, not a promise. Every operation happens locally in your browser. No file is ever uploaded anywhere. No account, no sign-up, no email required. Nothing is collected or tracked, and the extension keeps working fully offline. WHAT IT DOES LocalPDF Toolkit bundles 41 practical document tools into one lightweight extension. • Save any webpage as a clean, readable PDF. • Combine multiple documents into one, or split a document into smaller parts. A visual page manager lets you reorder, rotate, extract or delete pages, remove blank pages, crop margins, print several pages per sheet, and split double-page A3 scans. • Turn a PDF into an editable Word, Excel, Markdown or HTML document, or build a PDF from your text, Markdown, Excel or Word files. Export PDF pages as images, combine images into a PDF, and extract the text or pictures inside for reuse. • Add text or image watermarks, sign documents, insert page numbers, headers, footers and date stamps. Highlight passages, add hyperlinks, and mask sensitive details such as ID numbers before sharing. • Compress large files to save space, protect documents with passwords, edit metadata, and inspect document details. • Office helpers included: print passport photos on standard photo sheets with automatic layout, listen to any document with built-in text-to-speech, and compare two versions of a document to spot every difference. WHY IT MATTERS Online PDF tools quietly upload your documents to their servers. LocalPDF Toolkit keeps everything in the browser sandbox — nothing is transmitted, ever. If you handle contracts, payslips, ID scans or medical records at work or at home, this is the safe choice. The interface automatically matches 21 system languages and needs no setup. There is nothing to upload and no queue to wait in, so results are instant even for large files. 中文说明 本地 PDF 工具箱：41 项文档工具全部在浏览器内本地完成，文件不离开你的电脑。合并、拆分、整理页面、格式转换、水印签名、加密压缩、证件照排版等一应俱全。无上传、无服务器、无账号、无数据收集，可完全离线使用。合同、发票、证件等敏感文件放心处理。
