ISO extractor for disk images
Tool for opening ISO disk images in your browser. Reads ISO9660, Joliet, Rock Ridge and UDF — including 16 GB+ Windows installer and Linux Live ISOs that most other web extractors choke on. Common uses: pull a single driver out of a Windows installer without burning it to USB, peek into a Linux distro ISO to confirm it has the package you need before flashing, extract one font or asset from a software ISO, or verify a published SHA-256 checksum.
How to extract an ISO file
Drag an .iso file onto the upload zone or click to browse. UDF, Joliet and Rock Ridge are detected automatically.
Expand folders to see contents. Press / to filter by name, arrow keys to navigate.
Click any text or image file to preview it inline; bytes are read on demand.
Click SHA-256 to compute the hash of the whole ISO and compare against a published checksum.
Pick a folder via File System Access for streamed writes, or fall back to per-file downloads / STORE ZIP.
Browse, preview and pull files out of any ISO file
Why this is the strongest browser ISO extractor
ISO extractor — common questions
Does this work on UDF ISOs?
Yes. UDF 1.02, 2.01, 2.50 and 2.60 are all parsed, including the long allocation extents that >4 GB files need. Most online ISO extractors only read the ISO9660 fallback layer and miss the real file tree on modern installer images.
Can it open a 16 GB Windows installer image?
Yes, and that is the case most browser extractors fail on. The trick is never holding the image in memory: the directory structures live at known offsets, so opening one reads a few kilobytes rather than the whole file, and pulling a single file out streams only that file's extents. Even the SHA-256 of the image is computed by streaming it past the hash function, so verifying a 16 GB download costs time but not RAM. What does set a real limit is the file you extract, not the image it came from.
Can I look inside a file without extracting it?
Yes for the things worth looking at before committing to a download. The directory listing comes straight from the image structures, so names, sizes and dates are there immediately, and text files and images can be shown from their extents alone. The El Torito record is worth checking too: it says whether the image is bootable, whether the boot path is BIOS or UEFI, and what emulation it declares — which is exactly what you want to know before writing an ISO to a stick and finding out the hard way.
How do I extract a bootable image?
If the ISO has an El Torito boot record, the Boot section shows the platform and emulation mode. Click "Extract boot image" to download the boot image as a standalone .img file.
Which tools is this an alternative to?
For the common "I just need one file out of this ISO" case, this replaces 7-Zip, PowerISO, WinISO, MagicISO, or mounting the image with sudo mount -o loop. Useful when you are on a locked-down work machine where you cannot install desktop software, or on a Mac where the built-in DiskImageMounter cannot read UDF ISOs reliably.
I closed the tab — do I lose my place?
When you reopen the page, you will be asked to re-select the same ISO file; browsing state and selection are restored from a 7-day IndexedDB session.
What about encrypted ISOs?
Standard ISO9660 and UDF have no encryption. If the ISO is wrapped in an outer container (BitLocker, encrypted DMG, password-protected 7-Zip), you need to decrypt that wrapper first.
Can I use the result with my virtual machine?
Yes. Extracted files are bit-identical to the originals; mounting the ISO in VirtualBox, VMware, QEMU or Hyper-V will see the same content.
