01Why this zip tool
Archives, without installs.
Four reasons people open this tab on shared computers and locked-down corporate laptops.
- 01
Zip and unzip in one tab
Drag files in to create an archive, or drop a zip to expand its contents. Same UI, both directions.
- 02
Browse zip contents first
See file names, sizes, and folder structure before extracting. Useful for grabbing one file out of a large archive without unpacking everything.
- 03
Password-protect new archives
Add a password when creating a zip so it can travel safely through email, chat, or shared drives.
- 04
Files never leave your device
Compression and extraction run in your browser via WASM. Files never upload — even large archives stay private.
02How it works
Drop, browse, download.
- ModeZipUnzip
Step 1Pick zip or unzip mode
Zip mode bundles selected files into a new archive. Unzip mode opens an existing .zip to browse or extract contents.
- Drop filesFiles3 selected
Step 2Drop your files
Drag in the files (or the zip), or use the file picker. The list of items appears with names and sizes.

Step 3Download the result
Zip: download the new archive. Unzip: extract the files (one at a time or all at once).
03Use cases
Where zips show up.
Email attachments, vendor downloads, project archives — the everyday zip moments.
Send 10 files as one attachment
Email clients balk at many attachments. Zip them into one archive and send a single tidy file.
10 photos → photos.zipOpen a downloaded zip in the browser
Don't want to install software on a shared computer? Open the zip here, grab the file you need, leave the rest.
Receipt PDF inside a vendor zipBundle for upload to a server
Some services accept zip uploads but not folders. Pack the directory in two clicks and upload the single file.
Asset bundle for CDN uploadPassword-share a sensitive file
Need to email a contract or scan to a counterparty? Zip with a password and share the password through a separate channel.
Contract.zip · password via SMSArchive a finished project folder
Wrap up a project by zipping the working folder before clearing your desktop. One file, easy to drop into long-term storage.
Project Q1.zip → cloud archiveCompress before backup
Cloud backup quotas tighten as folders grow. Zipping first cuts size meaningfully for text-heavy folders.
Source code folder → 30% size
04Quick tips
Zip smart.
Four notes that keep archives useful and password-protection meaningful.
- 01
Zip isn't great for already-compressed files
JPEGs, MP4s, and PDFs are mostly pre-compressed. Zipping them barely changes size — the value is in bundling, not shrinking.
- 02
Use a strong password if you protect
Zip passwords protect content from casual readers. A weak password (six letters, dictionary word) won't survive automated cracking. Use a real one.
- 03
Treat password-encrypted zip as 'safe-ish'
Even AES-encrypted zips leak file names and folder structure. For high-stakes secrecy, use a real encryption tool that hides metadata too.
- 04
Large archives stay in memory
Everything runs in your browser tab. Multi-gigabyte archives may strain RAM. For huge jobs, fall back to a desktop tool.
05Loved by
IT, freelancers, and marketers.
Helping users open a vendor zip without admin install rights. Open in the browser, grab what they need, problem solved.
Zip a delivery folder, password-protect, send. Client unzips on their side; nobody has to install anything.
Bundling campaign assets for partners. Two minutes to a clean zip — easier than chasing the right shared-drive permissions.
06Questions
Zip, plainly answered.
Questions before your first drop. Missing one? hello@wirelogs.com.
01Are my files uploaded to a server?
No. Everything happens in your browser via WebAssembly. Files never leave your device — important when zipping or unzipping sensitive content.
02How large a zip can I handle?
Up to several gigabytes for unzip, hundreds of megabytes for zip — limited by your browser tab's available memory. For very large jobs, a desktop tool is more comfortable.
03Does it support password-encrypted zips?
Yes. You can create AES-256 password-protected archives and extract password-protected ones. AES-encrypted zips offer real confidentiality (legacy ZipCrypto does not).
04Can I unzip a single file without extracting all?
Yes. The contents view lets you preview the structure and download individual files.
05What formats are supported?
Standard .zip archives. For other formats (.rar, .7z, .tar.gz), use a dedicated desktop tool — those aren't natively supported by browsers.
06Is it free?
Yes. No sign-up, no usage cap, no watermark.
