About this tool
About PDF Tools
Working with PDFs usually means choosing between desktop software that costs hundreds of dollars per year or cloud services that upload your documents to a server you don't control. These free browser-based PDF tools offer a third option: professional-grade PDF processing that runs entirely on your device, with no file upload, no account, and no cost.
Why Browser-Based PDF Tools Are Better
Every tool in this collection uses the pdf-lib, PDF.js, and qpdf-wasm libraries to read, modify, and write PDF files directly in your browser's memory. Your files are loaded from disk, processed locally, and downloaded straight back to your device. No data is ever transmitted to a server — making these tools safe for confidential documents, legal contracts, financial records, and any sensitive material you would never want stored on a third-party server.
Because processing happens client-side, the tools work offline once the page has loaded. There are no file-size limits imposed by a server, no queues, and no waiting. Large PDFs process as fast as your device can handle them.
What's in This Free PDF Toolkit
Use our PDF Merger to combine files, PDF Compressor to reduce file size, or PDF Password Protector to secure your documents — all without uploading anything to a server.
PDF Merger combines multiple PDF files into a single document. Drag files into any order, preview thumbnails, and download the merged result instantly. PDF Splitter extracts any page range — enter 1–5, 8, 12–15, or click individual thumbnails. PDF Password Protector adds 128-bit or 256-bit encryption with permission controls for printing, copying, and editing. PDF Unlock removes open passwords and owner restrictions from PDFs you own.
PDF Compressor reduces file size by re-rendering pages at lower quality. PDF Page Organizer lets you reorder, rotate, and delete individual pages using a drag-and-drop visual grid. PDF Metadata Editor reads and updates the hidden title, author, subject, keywords, and creator fields. PDF Watermark stamps text or image marks across every page at custom opacity, position, and rotation.
Images to PDF combines JPG, PNG, and WebP images into a single PDF document with configurable page size, margins, and image fit. PDF to Images exports each page as PNG, JPEG, or WebP at a chosen DPI. HTML / Markdown to PDF converts written content to a styled PDF with a live split-pane preview, custom fonts, and paper size controls.
Privacy and Security
Unlike tools like SmallPDF or iLovePDF, these tools run entirely in your browser — your files never leave your device. No server logs, no file retention policies, no risk of your documents appearing in a data breach. Open, process, download — that's the entire workflow.
When to Use Browser-Based PDF Tools
These tools are particularly useful when handling confidential documents — tax returns, contracts, payslips, medical records, or legal agreements — where uploading to a third-party server creates unnecessary risk. Because all processing happens in your browser using WebAssembly, the tools work offline once the page has loaded. There are no file-size limits imposed by a remote server, no queues, and no waiting. A 200 MB PDF processes as fast as your device can handle it, with no upload progress bar, no timeout errors, and no subscription required.

Frequently Asked Questions
Yes — every tool is completely free with no file-size caps, no page limits, no daily usage quota, and no watermark on the output. No account or credit card is required. Because all processing runs in your browser there are no server costs and therefore no premium tier.
No. The PDF tools use browser-based libraries — pdf-lib, PDF.js, and qpdf-wasm — to process files entirely in your browser. Your PDFs are read from disk into browser memory, modified locally, and downloaded directly to your device. No data is transmitted to any server at any point, making these tools safe for confidential documents, legal contracts, and financial records.
Yes. The PDF Merger accepts any number of PDF files at once. Drag them into the drop zone, reorder them by dragging the thumbnail cards to your preferred sequence, and click Merge. The merged file downloads instantly with pages in exactly the order you specified.
Open the PDF Splitter and upload your PDF. Enter a page range (e.g. 1–5 or 3, 7, 11–14), or click individual thumbnail pages to select them visually. Click Split to download a new PDF containing only the pages you selected. Multiple split operations are independent so you can extract several different ranges from the same source file.
The PDF Compressor works by re-rendering pages to JPEG images at lower quality. Text and vector content becomes a rasterised image, which trades crispness for file size. For scanned PDFs and image-heavy files this is ideal. For text-only PDFs, compression will reduce sharpness — use it only when file size reduction outweighs text clarity.
Yes. Use PDF to Images to export pages as PNG, JPEG, or WebP files, then use Images to PDF to recombine them. You can choose which pages to export and set the resolution, then arrange the images in any order when creating the new PDF.
PDF Unlock removes open passwords from PDFs you own — enter the open password and download an unrestricted copy. The other PDF tools (Splitter, Merger, Watermark, Page Organizer, etc.) use pdf-lib's ignoreEncryption option, which allows processing of owner-restricted PDFs that have no open password set.
The PDF Password Protector lets you set an open password (required to open the file) and permission restrictions (prevent printing, copying, or editing). Choose between 128-bit RC4 and 256-bit AES encryption. Upload your PDF, set the password and permissions, and download the protected file. The password is never sent to a server — all encryption runs locally using the qpdf-wasm library.
PDF metadata is a hidden layer of descriptive information — fields like Title, Author, Subject, Keywords, and Creator — stored separately from the visible page content. It appears in the document properties panel of PDF viewers and in Windows Explorer file details. Search engines and document management systems use it to index files. The PDF Metadata Editor lets you read and update these fields without touching the visible content at all.
