Are these tools really 100% free?
Yes. All tools on LocalFileNest are completely free to use without restrictions. No account signup is required, no credit card is ever requested, and no promotional watermarks are inserted.
Are my files uploaded to a remote server?
No. All processing (image compression, conversions, PDF optimizations, Office document handling) occurs locally inside your web browser using Web Workers, Canvas, WebAssembly, and JSZip. Your files stay strictly on your device.
Is there a maximum file size limit?
Because operations utilize your local device's memory, there are no artificial backend restrictions. We recommend files up to 50 MB or 100 MB for optimal responsiveness across desktop and mobile browsers.
What file formats are supported?
We support JPG, PNG, WebP, SVG, HEIC/HEIF, AVIF raster & vector formats, standard PDF documents, and Microsoft Office / LibreOffice packages (.docx, .pptx, .xlsx, .odt, .ods, .odp).
Can I use LocalFileNest on my mobile phone or tablet?
Yes. LocalFileNest is fully responsive with touch-optimized controls designed for Safari Mobile, Chrome Android, Edge, and Firefox on mobile devices.
Why is LocalFileNest free?
Because processing runs locally on your client machine rather than on power-hungry cloud server farms, our hosting footprint is minimal. We believe in a lightweight, accessible, and privacy-respecting web.
Are my files retained or logged anywhere after processing?
No. Nothing is stored. As soon as you refresh or close your browser tab, all temporary memory allocations are immediately freed by your browser.
