--- title: "Extract ISO Online — Open Disc Images | Compress Pro" description: "Open ISO disc images in your browser and pull out the files — no mounting, no virtual drives, no admin rights. Runs locally; nothing is uploaded." canonical: https://compress-pro.com/extract-iso --- # Extract ISO images. > Look inside ISO disc images — files out, never mounted. An ISO wants to be mounted as a virtual disc before it shows its files — an odd ceremony when you just need one installer or driver out of it. Drop the image here and **its file tree reads directly in your browser**: every file becomes its own download, no drive letters involved. **No uploads · No ads · Free & open source.** ## How it works 1. Drop files anywhere on the page, click to browse, or paste with Ctrl/⌘ + V. 2. Pick a quality or preset — or set an exact target size and let the tool find it. 3. Compress, compare before/after, and download — individually or as a ZIP. ## What survives, what cannot Every FILE on the disc extracts byte-perfect. What does not survive is bootability — boot sectors are disc plumbing, not files, so extracting (or [converting to ZIP](https://compress-pro.com/iso-to-zip)) never yields a bootable copy. To write a bootable USB, hand the original ISO to Rufus or balenaEtcher and let it do its thing. ## Frequently asked questions ### Do I need admin rights or a virtual drive? No — that is the point. The image is parsed as a file, in the browser sandbox; nothing touches the operating system, so it works on locked-down work machines where mounting is blocked. ### Which disc formats read correctly? ISO9660 with Joliet and Rock Ridge — the shape of software discs, driver CDs and OS images — plus UDF-based media in most cases. Copy-protected commercial video discs are the exception. ### Can I make the ISO into a ZIP instead? Yes — the ISO to ZIP converter repacks the whole image as one ZIP in a single step, which beats downloading files one by one when you want everything. ### Is it private? Yes. The archive is opened and unpacked on your own device — its contents are never uploaded, and a password, if one is needed, is used locally and never transmitted. The server does nothing but deliver this page. Want proof? Run one file through, switch your connection off, and run another — it still works. ## Related tools - [Convert ISO to ZIP](https://compress-pro.com/iso-to-zip) - [Zip & Unzip files](https://compress-pro.com/zip-files) - [Extract RAR archives](https://compress-pro.com/extract-rar) --- Part of [Compress Pro](https://compress-pro.com/) — every tool page has a markdown twin at `.md`.
