File Converter - Formatter - To - Free

 File conversion does not need a server. FileFormer runs ffmpeg, ImageMagick and Ghostscript as WebAssembly in your browser, so PDF, image and audio conversion happens on your own machine: no upload, no account, nothing stored elsewhere. That is the whole point of https://fileformer.com

 Every online file converter starts by asking you to upload the file. For a photo that is harmless. For a contract, a medical record or a client export it is a real decision: the file leaves your machine and lands on a server whose retention and breach policy you do not control. FileFormer runs the conversion in your browser instead. WebAssembly builds of ffmpeg, ImageMagick and Ghostscript do the work in the tab, so the file is read from disk and written back without ever being transmitted. The honest tradeoffs: the first load pulls a few megabytes of WebAssembly, browser memory is capped so very large files need chunking, and there is no server-side batching. The payoff is that there is nothing to audit: no upload log, no retention window, no account. Convert PDF, JPG, PNG, WEBP, MP3 and MP4 at https://fileformer.com

 If a PDF is too big to email, the usual advice is to run it through an online compressor. That means handing the file to a stranger. For a contract, an invoice or anything with client data in it, that is a bad trade. You can compress a PDF entirely inside your browser instead. Ghostscript compiles to WebAssembly, so the compression runs on your own machine: the file is read from disk, processed in memory, and saved back out. Nothing is uploaded, nothing is stored, and there is no server that could leak it later. Practical notes: image-heavy PDFs shrink the most (scans especially), text-only PDFs are already small so gains are modest, and very large files may need to be split first because browser memory is capped.
