PDF Tools
Free browser-based PDF tools: merge, split, convert images to PDF, and extract PDF pages as images. All processing happens locally — your files never leave your device.
PDF manipulation tools for merging multiple PDFs, splitting PDFs by page ranges, converting images to PDF (PNG/JPEG/WebP), and converting PDF pages to images. All processing is done client-side using browser-native APIs — files are never uploaded to external servers. Key tools: PDF Merge (combine unlimited files), PDF Split (extract specific page ranges), Image to PDF converter with quality controls.
Privacy-First PDF Processing
Most online PDF tools upload your documents to a server for processing. That means sensitive files — contracts, tax documents, medical records, legal paperwork — are sitting on someone else machine. ToolStand PDF tools are fundamentally different: everything processes locally in your browser using WebAssembly-powered libraries like PDF-lib and PDF.js. Your files never leave your device. This privacy-first approach is especially important for legal, medical, and financial documents where confidentiality is non-negotiable.
Complete PDF Workflow
ToolStand covers the four most common PDF operations: merging multiple PDFs into one, splitting a PDF by page ranges, converting images (JPG, PNG, WebP) into PDF documents, and extracting PDF pages as high-quality images. Together, these four tools handle most PDF tasks that would otherwise require expensive desktop software or risky online services.
Speed and Convenience
Local processing means instant results — no waiting for uploads to complete, no server queues, no download delays. Drag and drop your files, reorder pages visually, adjust settings, and download the result. The tools work on desktop and mobile, so you can process PDFs from any device. No accounts, no subscriptions, no usage limits — process as many PDFs as you need, forever free.

How to Choose the Right PDF Tool
PDF tasks break into two categories: working with PDF files themselves, and converting between PDF and image formats. Pick your tool based on the direction of the conversion.
PDF Manipulation
| Goal | Best Tool | Why |
|---|---|---|
| Combine multiple PDFs | PDF Merge | Unlimited files, drag-and-drop reorder, preserves quality |
| Extract specific pages | PDF Split | Page ranges, individual extraction, odd/even support |
| Convert PDF pages to images | PDF to Image | PNG/JPG/WebP output, high-quality PDF.js rendering |
Image & PDF Conversion
| Goal | Best Tool | Why |
|---|---|---|
| Convert images to PDF | Image to PDF | JPG/PNG/WebP → PDF, A4/Letter with margins |
| Resize before conversion | Image Resizer | Canvas API, no upload, compress before PDF |
| Convert image formats | Image Format Converter | PNG↔JPEG↔WebP, batch processing |
Frequently Asked Questions
PDF Merge — does page order matter, and can I reorder files before merging?
Yes, order matters and you control it. The PDF Merge tool lets you drag and drop files into the exact order you want. The first file's pages come first, the last file's pages come last. If you need to change the order, reorder the file list before hitting merge. The tool concatenates entire PDFs — for fine-grained page reordering within a single PDF, split first with PDF Split, then re-merge in the desired order.
PDF Split — how precisely can I extract pages from a PDF?
The PDF Split tool supports three extraction modes: individual pages (each page becomes its own PDF), custom page ranges (e.g., 1-3,5,7-10), and odd/even page extraction. You specify exactly which pages you want. The tool preserves the original PDF quality — it extracts, not re-renders, so there's no quality loss.
Are my PDF files uploaded to a server? How does client-side PDF processing actually work?
No. All ToolStand PDF tools use PDF.js, Mozilla's JavaScript PDF library, running entirely in your browser. When you select a file, it's loaded into browser memory via the FileReader API. PDF.js parses and renders it locally. For merge and split operations, the browser constructs new PDFs in memory and triggers a download. At no point is your file transmitted to any external server — you can verify this by disconnecting your internet after the page loads; the tools still work.
PDF to Image — what resolution and format options do I have?
The PDF to Image converter renders PDF pages to PNG, JPG, or WebP using PDF.js's canvas renderer at the PDF's native resolution. For high-DPI output, the tool scales the render canvas. PNG is best for text-heavy pages (lossless), JPG for photo-heavy pages (smaller files), and WebP for a balance of quality and size. You can convert all pages at once or select specific page ranges.
Is there a file size limit for PDF tools, and how do large files affect performance?
There's no hard-coded limit, but browser memory is the practical constraint. PDF.js loads the entire PDF into memory, so very large files (100+ MB, 500+ pages) may cause slowdowns on devices with limited RAM. For most documents — contracts, reports, ebooks, presentations under 50 MB — performance is near-instant. The tools show a loading indicator while processing. If you're working with extremely large PDFs, split them first, process in chunks, then re-merge.
Can I use these tools for sensitive documents like contracts, tax forms, or medical records?
Yes — and this is actually the best use case for client-side PDF tools. Since files never leave your device, sensitive documents stay private. Unlike server-based PDF tools that upload your files, ToolStand's PDF.js-based processing means that tax returns, legal contracts, medical records, and financial statements are never transmitted anywhere. The Security and Privacy section above has more detail on the technical guarantees — but the short version: disconnect your internet after loading, and the tools work exactly the same.
