Frequently Asked Questions
Find answers to common questions about One Resizer's tools, privacy, exact KB sizing, and supported file formats.
1. Are my photos or documents uploaded to your servers?
No. All 36 tools operate locally inside your web browser. Your files never leave your device, ensuring maximum privacy and security for confidential documents.
2. How do I resize an image to an exact size like 20 KB or 50 KB?
Use the Image Resizer or Signature Resizer tool. Enter your target file size in the "Target KB" input field. Our binary search compression engine will automatically iterate to produce a file within 1 KB of your target.
3. Is One Resizer completely free to use?
Yes. All standard image, PDF, document, and QR utilities are 100% free with no hidden charges or required software downloads.
