How to Compress Photos Inside Zip Files Online (Without Unzipping)

Zipped photo folders are everywhere—whether you're submitting a form, sharing client deliverables, or uploading to cloud storage. But here's the catch:

Most online compressors can't compress images inside ZIP files. You're forced to extract, compress, and re-zip manually. Waste of time.

🚀 The Smarter Way: Use ZipnZip

ZipnZip is a modern web app that lets you:

• Compress multiple images within a ZIP file
• Preview before downloading
• Work directly from your mobile browser

No unzipping. No app installs.

2. Upload Your ZIP File

Just drag and drop or use the upload button. ZipnZip will scan your archive and extract all image files it can process.

3. Preview & Adjust Compression

You can:
