Tips & Best Practices

  • →Compression level 6 is recommended for most use cases — good compression without too much waiting.
  • →Level 0 creates a ZIP with no compression (just packaging) — faster for already-compressed files like JPG, MP4, and ZIP.
  • →Already-compressed files (JPEG, MP4, ZIP, PDF) compress very little — most savings come from text, raw images, and uncompressed audio.
  • →ZIP archives are great for sharing multiple files as a single download link.

Frequently Asked Questions

How do I create a ZIP file online for free?

Drag your files into ezyimg's ZIP Compressor, set the compression level, name your archive, and click Create ZIP. The ZIP is created in your browser and downloaded automatically.

What files can I add to a ZIP?

Any file type — images (JPG, PNG, WebP), videos (MP4, MOV), documents (PDF, DOCX), audio files (MP3, WAV), and more. There is no file type restriction.

Does a ZIP file reduce file sizes?

ZIP compression is most effective on text, CSV, XML, and uncompressed image formats (like BMP or TIFF). Already-compressed files like JPEG, MP4, and MP3 see little reduction.

What is the maximum compression level?

Level 9 is maximum compression — it takes longer but produces the smallest ZIP file. For most use cases, level 6 offers the best trade-off between speed and compression ratio.

Is there a file size limit for ZIP creation?

No — all processing runs in your browser using JavaScript. Very large files (multiple GB) may be slow or exceed available browser memory.
