# Convert ISO to ZIP.

> Disc image in, plain ZIP of its files out — no installs.

An ISO is a snapshot of a whole disc; sometimes all you want is the files inside without mounting anything. Drop the image here and its file tree is read in your browser and repacked as an ordinary ZIP — **no virtual drives, no admin rights, no upload**.

**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.

## ISO is an archive that pretends to be a disc

File managers treat ISOs specially because they emulate optical media, but structurally an ISO is just a read-only archive with a filesystem inside. Reading it as one — the way this converter does — skips the whole mount-extract-unmount dance. The files land in a [ZIP](https://compress-pro.com/zip-files) that opens anywhere, or convert onward to [7Z](https://compress-pro.com/zip-to-7z) if size matters more.

## Frequently asked questions

### Will the ZIP still be bootable like the ISO?

No — boot sectors and disc metadata are not files, so they do not survive any ISO-to-ZIP conversion. This is for getting at the CONTENT of an image. To write a bootable USB stick, use the original ISO with a tool like Rufus or balenaEtcher.

### Which ISO variants are readable?

Standard ISO9660 with Joliet and Rock Ridge extensions — which covers software discs, driver CDs and most downloads. UDF-based video DVDs generally read too; copy-protected commercial discs do not.

### Can I just browse the ISO without making a ZIP?

Yes — the Extract op on the archive tab lists every file in the image as its own download, no repacking involved. This page is the one-click version for when a single ZIP is the goal.

### Is it private?

Yes. Archives are built and converted entirely in your browser — neither the archive nor the files inside it are ever uploaded, and any password you set is applied locally. The server does nothing but deliver this page. Want proof? Run one file through, switch your connection off, and run another — it still works.
