Create ZIP (ZIP / RAR / 7Z Archiving)

This tool collects and compresses multiple files into a single archive file. The purpose is simple: smaller size, sharing with a single file, organized archiving and, if necessary, password protection.

What does it do?

• Converts multiple files into a single archive:
  • ZIP (highest compatibility)
  • 7Z (generally higher compression potential)
  • RAR (common, with strong additional features in some scenarios)
• Offers compression settings:
  • Fast / Normal / Maximum (level)
• Optional security:
  • Password encryption
  • (Optional) “hide file names” (especially a strong use in 7Z)

Note: AES-based encryption is common in ZIP and 7Z; the 7Z format explicitly supports AES-256 encryption.  

Specification/application notes on the ZIP side are defined through PKWARE APPNOTE; details such as AES usage are included here.  

How to use?

1. Upload files (multiple select / drag and drop)
2. Select Format: ZIP / RAR / 7Z
3. Select Compression Level: Fast / Balanced / Maximum
4. (Optional) Set a Password
5. Create → download the archive

Format selection (user clear guide)

ZIP (most compatible)

• Opens on almost every device/operating system.
• There may be a need to choose between “old compatibility” and “strong encryption” (e.g., ZipCrypto vs AES). The compatibility difference between ZipCrypto/AES options in ZIP is specifically noted in 7-Zip interface documents.  

7Z (high compression + strong encryption)

• The 7Z format supports AES-256 encryption and methods that provide high ratios like “solid compression”.  
• Gives a “more serious” perception for jobs requiring password protection.

RAR (common ecosystem + damage tolerance approach)

• RAR has features aimed at repairing damaged archives, such as “recovery record” (slightly increases archive size but provides recovery chance).  

Features (fine-tuning that brings transformation)

1) Compression level

• Fast: finishes quickly on large files, lower ratio
• Balanced: ideal for most users
• Maximum: smaller file, longer time

2) Archive organization

• Protect files with folder/root structure
• Automatic naming: archive-2026-01-02.zip like
• “Keep folder name” option (critical especially in project deliveries)

3) Password and encryption

• Set password + re validation
• (If available) option to encrypt file names (very valuable in 7Z; even the file list becomes invisible)

4) Large file / long path name warnings (real-life breaking point)

On Windows, the classic path length limit is MAX_PATH ~260 characters; the user may experience “error while extracting”. This limitation is due to Windows API.  

Therefore, a small warning text in the tool reduces the support burden after conversion: “Do not use a very deep folder structure, shorten file names.”

Use cases

• Sending files in a single package without hitting email attachment limits
• Agency deliveries: making design files + fonts + brief into a single archive
• Marketplace/product content packages: images + descriptions + documents
• Password-protected “custom” file sharing

FAQ

Should I choose ZIP or 7Z?

If you want compatibility, choose ZIP. If you aim for stronger encryption and higher compression, choose 7Z. (7Z’s AES-256 support is clear.)  

Can encrypted ZIP be opened everywhere?

Compatibility may vary in some types of ZIP encryption (ZipCrypto/AES). Therefore, it would be correct to put clear option names like “Compatible encryption” and “Strong encryption” in the tool.  

What if I get a ‘path too long’ error while extracting the archive?

This usually stems from Windows’ path length limit; shortening folder depth and file names solves the issue.
