1. Merging PDFs: The Seamless Way
Merging files is the most common PDF task. With RefineDoc, you can drag and drop multiple files and reorder them instantly. Since the processing happens on your local machine using WASM (WebAssembly), there's no progress bar waiting for an upload to finish.
Pro Tip:
Look for tools that offer a 'Preview' before merging to ensure page orientations are consistent across different document sources.
2. Precision Splitting
Extracting a single page or splitting a 500-page manual shouldn't take minutes. Modern tools allow you to visually select ranges. RefineDoc’s split tool provides instant thumbnails for every page without ever sending a byte to a server.
The 2026 Comparison: Privacy vs. Convenience

3. Compression without Quality Loss
Most online compressors aggressively downsample images. In 2026, look for 'Smart Compression' that identifies text vectors vs. raster images. RefineDoc uses a proprietary client-side engine that shrinks files up to 90% while keeping text crisp.
