Reduce JPG Size to 100KB – Questions & Answers

Does reducing JPG size to 100KB change the pixel dimensions?
Only if the original resolution is too vast to fit within 100KB at minimum compression quality. Otherwise, your original pixel dimensions are preserved.
Can I convert a PNG to a 100KB JPG?
Yes, if you upload a PNG, our tool will convert it to a lightweight JPG that satisfies the 100KB target.
Are my JPG files kept confidential?
Absolutely. No file upload occurs. All processing happens in your device browser RAM.
What happens to transparency when converting PNG to JPG?
Any transparent background areas are filled with crisp white (or your chosen background color).
