Frequently Asked Questions

Why are online tools so slow for batches?

You're uploading hundreds of MBs (slow), processing in small batches (queue wait), then downloading results (slow again). Desktop tools skip all that. For 100 images (200MB), online tools take 25-35 minutes while Diwadi takes 30-60 seconds.

Is my data really safe with Diwadi?

Yes. Diwadi processes everything locally on your computer. We literally cannot access your images - they never reach our servers. Online tools upload your images to third-party servers where they're stored temporarily (1-24 hours) and processed by unknown infrastructure.

Can I compress 1000 images at once?

Yes! Diwadi supports unlimited batch processing. Just drag your entire folder. Online tools typically limit batches to 1-20 images at a time due to server resource constraints.

What about high-resolution photos (50MB+ files)?

Diwadi handles unlimited file sizes. Online tools typically reject files >5-10MB. If you have high-res photos, RAW conversions, or large product images, Diwadi is your only realistic option.

Do I need internet connection?

No! Diwadi works completely offline, perfect for travel, flights, or secure environments. Online tools require constant internet connection for upload, processing, and download.

Will quality suffer?

No. Diwadi uses the same algorithms (mozjpeg, pngquant, etc.) as online tools, just locally. Both produce excellent quality - the difference is speed, privacy, and unlimited processing.

Are online tools really free?

Partially. Free tiers have severe limitations: 20 images/month, 5MB limits, slow processing. To get features comparable to Diwadi (unlimited, no watermarks, batch processing), you'd pay $6-25/month. Diwadi is free.

Can I still use online tools sometimes?

Absolutely! For true one-time compression of 1-5 small images when you can't install software, online tools are convenient. But for regular use, large files, or privacy-sensitive content, desktop tools offer better value.

Bottom Line

Online tools = convenient for 1-5 small images.
Diwadi = faster, more private, unlimited for everyone else.
