How to Convert PDF to PDF Locally in 3 Steps

No account registration, no cloud queues, and zero file size throttling.

Select or Drag PDF Files into Local Memory

Drop one or multiple PDF files directly into the Obsidian dropzone above. Files are read directly into your browser's isolated ArrayBuffer memory without uploading a single byte to any server.

Tune WebAssembly Quality & Output Parameters

Adjust compression quality, target resolution scale, or document pagination settings. Our multi-threaded Web Worker pool automatically scales across your CPU cores.

Instant Download or One-Click .ZIP Archive

Save converted PDF files individually or bundle your entire batch into a high-speed compressed .ZIP archive using our in-memory fflate engine.

Why 100% Client-Side WebAssembly Conversion Matters

Traditional online file converters upload your personal photos, financial PDFs, and enterprise spreadsheets to remote cloud servers where files may be logged, cached, or exposed to third-party breaches. FiletoFiles.com eliminates server uploads completely.

By compiling industry-standard C/C++ and Rust codecs (libwebp, libaom AVIF, MozJPEG, libheif, PDF.js, and SheetJS) into WebAssembly (WASM) running inside dedicated Web Workers, every conversion executes directly on your device's CPU and RAM.

✓ Zero Data Exfiltration: Ideal for confidential medical, legal, tax, and enterprise NDA documents.
✓ Multi-Core Hardware Speed: Uses navigator.hardwareConcurrency to process batches in parallel without freezing your browser UI.
✓ Zero Upload/Download Bandwidth Wait: Convert 100MB+ batches instantaneously even on slow or offline connections.

Frequently Asked Questions (PDF to PDF)

Can I extract specific page ranges or split every single page? +

Both! Leave the Page Range input blank to split every page into its own standalone PDF, or enter ranges like '1-3, 5, 8-10' to extract only those pages.

How do I download all the split PDF pages easily? +

Each extracted page appears in your results list for individual download, or you can click 'Download All (.ZIP)' to get all split PDFs in one archive.

Is the extracted PDF text still selectable and searchable? +

Yes! Because we extract native PDF page nodes via pdf-lib without rasterizing, all text, vectors, and formatting remain 100% original.

Are sensitive legal or financial PDFs uploaded anywhere? +

Never. Splitting happens strictly inside your device's browser memory.

How fast does it split a 100-page PDF? +

Usually under 1 second because there is zero upload or download latency.
