Bundle Files Into a RAR-Style Archive

Why Use Our RAR File Maker?
One-Click Archive
Drop any number of files (any type) into the upload area and the tool packs them into a single archive in one click. Each file is preserved exactly as-is, no re-encoding, no quality loss. Useful for emailing many files at once, sharing project bundles, or batch-uploading to portals that accept only archive files.
Live File Manager
Every file you add appears in a tidy table with its name (and a type-specific icon for images, PDFs, documents, audio, video, and code), individual size, and a remove button. Click Add More to append more files at any time, or × to remove a single entry. The live total size readout updates instantly.
DEFLATE Compression
The output uses DEFLATE compression at level 6, the same compression that powers ZIP and RAR file formats. Already-compressed files (JPGs, MP3s, MP4s, PDFs) only shrink slightly, but text files, source code, and uncompressed documents typically reduce by 50-80%. Bundling many files into one is the main convenience either way.
Private, No Upload
Your files never leave your device. The archive is built entirely in your browser using ZIP engine and the HTML5 File API. No file is sent to any server, no account is needed, and nothing is stored. The archive is generated locally and saved directly to your downloads folder.

Frequently Asked Questions
Common questions about creating RAR archives in the browser.
Is this a real RAR file?
Honest answer: no. The RAR format itself is proprietary and only WinRAR (the original creator) can produce true RAR files. No JavaScript library can create real RAR archives in the browser. This tool builds a standard DEFLATE-compressed archive (the same format used by ZIP) and saves it with a .rar extension. WinRAR, 7-Zip, and most archive managers will still open it without complaint, but a strict tool that checks the file signature will see it as a ZIP. If you need a true RAR file, use the desktop WinRAR application.
How is this different from the Create ZIP tool?
Functionally, the underlying engine is the same, both use ZIP engine and DEFLATE compression. The only difference is the output file extension and label. Use this tool if you specifically need a .rar extension on the file. Use the Create ZIP tool if you want a clean ZIP with proper extension and the same broad compatibility.
How many files can I add?
There is no hard limit, but practical browser memory limits start to bite around several hundred files or several gigabytes of total size. Each file is loaded into memory as an ArrayBuffer before being added to the archive, so very large bundles may cause the browser to slow down or run out of memory. If that happens, split the bundle in two.
Does the tool upload my files to a server?
No. ZIP engine runs entirely in your browser. Your files are loaded into memory locally, compressed locally, and saved locally. Nothing is transmitted to any server, and nothing is stored after you close the page.
