Frequently Asked Questions (FAQ)
Q: Is it safe to use ITKB Image Resizer? Do my private photos get uploaded?
Absolutely safe. This tool uses local Client-Side JavaScript processing. Your image files are managed inside your browser memory and are never uploaded to any cloud storage. You can securely adjust sensitive files like passport scans, ID photos, or confidential documents.
Q: What is the optimal quality setting to minimize KB size without losing clarity?
For most online job portals or school portals requiring files under 200KB or 500KB, setting the quality slider between 75% - 85% is highly recommended. This significantly reduces files size while keeping details incredibly sharp to the human eye.
Q: Why does the quality slider not work when choosing PNG format?
The PNG format uses lossless compression, which prioritizes preserving exact pixel details and transparency. It does not support quality percentage reduction. If you need to compress file sizes drastically, we suggest switching the output format to WebP or JPG.
