Private file conversion with useful guidance
Private Converter is built for everyday document and media tasks where you want a quick result without sending files to a remote conversion server. The tools run in your browser using local web APIs and WebAssembly, which means private files such as forms, invoices, images, and audio stay on your device while you convert, compress, resize, merge, split, or sign them.
Sign PDF free
Add a drawn, typed, or uploaded signature to a PDF without creating an account.
Compress PDF
Reduce PDF size in the browser before emailing or uploading a document.
Image to PDF
Turn JPG, PNG, or WebP images into a PDF document without uploading them.
When local conversion matters
Local processing is useful for forms, receipts, personal photos, scanned pages, and business files that you do not want copied to a third-party conversion queue. Some formats still need browser-supported libraries, but the conversion work happens on your device after the page loads.
What to check before downloading
Always open the converted file before sending it onward. For PDFs, confirm page order, text extraction, compression quality, and signature placement. For images and media, compare file size and visual quality so you choose the format that fits your use case.
Frequently asked questions
Are files uploaded to Private Converter?
No. The converter is designed around local browser processing. Your files are read by the page in your browser and are not sent to a server for conversion.
Can I use advanced tools without an account?
Yes. Batch conversion, image resizing, quality controls, PDF page sizing, and PDF signing are available without a paid account.
Why does the site show ads?
Ads help pay for hosting and development while keeping the conversion tools free to use. Ads are intended to appear alongside useful page content, not on empty status or navigation pages.
