How to Convert PNG to PNG Locally in 3 Steps
No account registration, no cloud queues, and zero file size throttling.
Select or Drag PNG Files into Local Memory
Drop one or multiple PNG 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 PNG 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.
