Unzip files online free — no app needed
Short answer: drop your ZIP file into the box above. The tool reads the archive in your browser, shows you every file and folder with sizes, lets you preview images and text documents, and download single files — or re-bundle everything into one new ZIP with Download all as ZIP. No signup, no install, nothing uploaded.
How it works
1. Drop a .zip file onto the box (or tap it on your phone) — it is read locally with the open-source JSZip library. 2. Browse the file list: folders are grouped, every file shows its uncompressed size. 3. Click Preview on any image or text file to look inside without downloading. 4. Click Download next to a single file to save just that one, or Download all as ZIP to get everything re-bundled as one archive.
This is genuinely useful on phones and locked-down computers: iPhones and many work laptops have no good built-in way to peek inside a ZIP and pull out one file. Here you can grab exactly the PDF, photo or document you need without extracting the whole thing.
ZIP vs RAR vs 7z — what this tool opens
This tool opens ZIP archives — the format every operating system (Windows, macOS, Android, iOS) can create natively, and the format email attachments and downloads use 99% of the time. It does not open RAR or 7z files: those are proprietary or specialized formats that need a desktop app like 7-Zip (free) or WinRAR. If someone sends you a .rar, convert or re-save it as .zip on a desktop first, then open it here.
Is it safe to unzip files online?
With most online unzip tools, your archive is uploaded to someone's server — a real risk if the ZIP contains contracts, personal photos or work documents. This tool is different: the archive is parsed entirely in your browser and never transmitted anywhere. As always, be careful with ZIPs from strangers: archives can contain malware, so only download and open files you trust, and let your antivirus scan anything executable.
Frequently asked questions
Is this ZIP extractor really free?
Yes — completely free, no signup, no limits on how many archives you open, and no watermarks or upsells. It runs on the open-source JSZip library directly in your browser.
Are my files uploaded to a server?
No. Your ZIP is read entirely in your browser with JavaScript — the file never leaves your device, is never sent to a server, and is never stored. You can verify this by watching your browser's network tab while using the tool.
Can I open password-protected ZIP files?
No — encrypted ZIPs cannot be opened in the browser. The file list may still show, but extracting will fail. Remove the password first with a desktop app like 7-Zip or WinRAR, then open the unprotected archive here.
What is the maximum ZIP file size?
There is no hard limit, but everything is held in your device's memory, so very large archives (roughly 250 MB and up) may slow down or crash mobile browsers. Desktop browsers handle multi-hundred-megabyte archives more comfortably.
Does it work on iPhone and Android?
Yes. It runs in any modern mobile browser — tap the box to pick a ZIP from your files, browse the contents, preview images and documents, and download what you need. No app install required.
Can I preview files before extracting them?
Yes. Click Preview on any image (JPG, PNG, GIF, WebP, SVG) to see it, or on any text file (TXT, JSON, CSV, Markdown, code files) to read its contents — without downloading anything.
Can I extract RAR or 7z files?
No — this tool opens ZIP archives only, which is the format every operating system creates natively. For RAR or 7z you need a desktop app like 7-Zip (free) or WinRAR.
How do I download all files at once?
Click "Download all as ZIP" and the tool re-bundles every file from the archive into a single new ZIP on your device. Or download files individually with the per-file Download buttons.
