Bundle files into a ZIP, or pull a ZIP back apart into its files, right here in your browser tab. Nothing is uploaded to a server — open your network tab if you don't believe it.
Add as many files as you like and bundle them into a single .zip. Click Preview on any file to check it before zipping. Folders keep their structure if your browser supports folder drops; otherwise add the files directly.
Drop in a .zip and pull out its contents. Preview a file before downloading it, grab files one at a time, or download everything at once. Files are cleared from the page automatically once downloaded.
Every tool on Quikbench follows the same rule: your files are read, archived (or unpacked), and turned into a download entirely inside this browser tab — nothing is ever uploaded to a server. You can also preview a file's contents before you commit to downloading it, and once something is downloaded, it's cleared from the page automatically.
Both directions run on the same library, JSZip, working entirely in your browser's memory. Add files and it packs them into a .zip; drop in a .zip and it unpacks the files inside. Either way, you can click Preview on any file to check what's inside before deciding to download it.
RAR is a proprietary format and 7z uses compression schemes that don't have a reliable, lightweight pure-JavaScript implementation. Rather than ship a shaky decoder that fails halfway through on certain archives, this tool sticks to .zip — the one archive format that's both universally supported and genuinely practical to handle entirely client-side.
Preview works for images (PNG, JPG, GIF, WebP, SVG) and text-based files (txt, md, json, csv, and common code file types) — these render their actual content right in the page. Office documents, PDFs, and other binary formats can't be safely rendered this way, so they show a clear "no preview available" message instead of guessing or showing something misleading. Download is always the reliable fallback for those.
Encrypted or password-protected ZIP files can't be opened here — the password would have to be sent somewhere to check it, which defeats the point of doing this locally. Extracting a very large archive, or compressing a large batch of files, is limited by how much memory your browser tab has available, since nothing is offloaded to a server.
Yes. Click Preview next to any file, before zipping or after extracting, to see it without downloading. Images and text-based files (txt, md, json, csv, code files, and similar) show their actual content. Other file types, like .docx or binary formats, show a message that no preview is available since they can't be safely rendered in the browser.
No. This tool works with ZIP archives only. RAR and 7z use proprietary or more complex compression formats that can't be reliably read in-browser, so only .zip is supported for both compressing and extracting.
There's no hard limit set by the tool, but everything happens in your browser's memory, so very large archives or a very large number of files are limited by your device's available RAM.
Once a file or ZIP has been downloaded, it's cleared from the page automatically. Nothing is kept in the browser tab after that, and nothing was ever sent to a server in the first place.
Yes — there's no limit, no account, and both compressing and extracting happen entirely in your browser.
