Frequently Asked Questions
How does the tool guarantee an exact KB size?
Our algorithm performs binary-search quantization and multi-pass resolution scaling in-memory, ensuring the final exported file size is strictly less than or equal to your requested limit without unnecessary loss of clarity.
Is it safe to upload government ID cards or signatures?
Yes, 100%. All processing happens entirely within your web browser's memory using HTML5 Canvas. Your documents and photos never leave your device.
