À propos
An online tool to set passwords on ZIP files. You can compress files and folders and protect them with a password.
Supports AES-256 encryption to protect files with high security level. It also supports batch compression of multiple files and password settings.
L'ensemble du traitement s'effectue dans le navigateur et les fichiers ne sont jamais envoyés au serveur.
Comment utiliser
Select Files
Drag & drop or select the files you want to password protect.
Set Password
Enter your password and choose the encryption method.
Save ZIP
Save the generated password-protected ZIP file.
Glossary
- ZIP Archive
- The legacy and universally recognized standard for compressing and archiving multiple disparate files/directories into a single, highly condensed saveable package.
- Encrypted ZIP
- A ZIP package locked cryptographically during the aggregation process. Any user attempting extraction is blocked unless possessing the accurate plaintext password.
- AES Encryption
- Advanced Encryption Standard. A military-grade algorithmic cypher utilized by this tool replacing the fundamentally flawed and easily hackable legacy "ZipCrypto" used by older 90's architecture.
- PPAP Concept
- An obsolete and notoriously insecure Japanese corporate phenomenon of emailing a ZIP file, followed immediately by another email containing the password. This tool exists partly to demonstrate modern alternatives.
- Client-Side Archiving
- The secure data-flow constraint executing the compression math purely harnessing HTML5 functionality resident locally on your machine, eliminating external cloud reliance entirely.
- zip.js Core
- The sophisticated JavaScript mathematical library built into this tool to handle the bitwise compression flawlessly across browsers globally.
- Extraction (Unzipping)
- The reverse-action decoding procedure deploying decompression algorithms recovering the exact structural and binary precision of the original packaged data upon password submission.
FAQ
- Q.Can my boss and IT department confidently trust this with classified data?
- Unconditionally yes. Strict client-node topology mandates that none of your documents cross network barriers. The complex byte-crunching encrypts within your screen securely ensuring supreme corporate secrecy.
- Q.Why is this superior to using the built-in Windows Zip utility?
- Older vanilla Windows versions utilize archaic and highly compromised encryption schemas ("ZipCrypto"). This bespoke online node injects modern robust parameters preventing brute-force trivialities instantly.
- Q.My recipient complains they receive an error while opening the archive. Fix?
- Since this constructs modern AES-secured bundles, recipients relying on outdated Windows 7 default extractors might face incompatibilities. Guide them softly toward installing modern free utilities like 7-Zip or WinRAR globally.
- Q.Will shoving massive 4K movie files into this cause a fiery crash?
- Probably. Browser memory boundaries limit client-side magic. We vehemently advise enforcing limits roughly below 200MB. Towering multi-gigabyte video encodings will inevitably asphyxiate your browser RAM, freezing Chrome violently.
- Q.Why do Japanese text filenames sometimes output as scrambled nonsense globally?
- Actually, our tool prevents exactly that bug! Outdated zip software encodes names haphazardly. We enforce strict UTF-8 Unicode protocols on file-metadata, ensuring Japanese character strings translate identically on Mac, Windows, or Linux platforms unharmed.
- Q.I catastrophically lost the custom password I just locked it with. Is there a back door reset?
- Mathematically devastating, but absolutely no. The cryptography relies entirely on the generated salt and your unique phrase without keeping logs. We physically possess zero mechanism unlocking your newly locked masterpiece if amnesia ensues tragically.
- Q.If the PPAP custom is dead and dangerous, how should I share sensitive things?
- Modern cyber-hygiene dictates utilizing enterprise-class cloud platforms (SharePoint, Google Workspace, Dropbox), assigning granular permission parameters, and dispensing strict link-access ensuring only verified authenticated identities unlock designated deliverables professionally.
