Nanivolt was built to solve a simple problem: why should you wait minutes to upload files to a server when compression can happen instantly in your browser?
Nanivolt was founded in 2024 with a revolutionary vision: file compression doesn't need to touch a server.
We noticed that while browser technology had advanced significantly, most file compression tools still required uploading files to remote servers. This meant:
So we built Nanivolt—a completely client-side compression tool that processes everything in your browser. No uploads, no waiting, no limits.
Nanivolt provides four core file compression tools, all processing entirely in your browser:
Reduce PDF file sizes by up to 90% without losing quality. Perfect for emailing documents, uploading to websites, or archiving files.
Optimize JPG, PNG, WebP, and GIF images with adjustable quality settings. Compress up to 10 images at once.
Combine multiple PDF files into one document. Drag and drop to reorder pages exactly how you want them.
Convert PDF pages to high-quality JPG images. Extract all pages or specific pages with customizable quality settings.
Your files never leave your device. All compression happens in your browser using cutting-edge JavaScript libraries. This means instant processing with zero privacy concerns.
Unlike competitors who limit files to 1-15GB, our client-side approach means Pro users can compress files of any size—even 50GB+ files that others reject.
Competitors charge $99/month for API access. We include it in our $8/month Pro plan with 1,000 calls per month. Perfect for developers and agencies.
Most tools delete your files after 24 hours. Pro users get permanent file history with secure cloud storage and re-download access from any device.
Processing starts instantly because there's no upload step. Whether your file is 1MB or 1GB, you see results in seconds—not minutes.
No hidden fees, no surprise charges. Free users get real tools (not demos), and Pro is just $8/month with a 30-day money-back guarantee.
We believe file compression should be:
Whether you're a student compressing lecture notes, a photographer optimizing portfolios, or a business handling sensitive documents—Nanivolt gives you the tools without the hassle.
Nanivolt is built with modern web technologies that enable client-side file processing:
All processing is done using Web Workers for optimal performance, ensuring your browser stays responsive even with large files.
