Frequently Asked Questions

How does the 50KB JPG compressor maintain sharp edges?▼
By using adaptive discrete cosine transform (DCT) quantization tables, our engine reduces high-frequency background noise first while preserving contrast across facial edges and text lines.
What happens if my original JPG is already close to 50KB?▼
Our smart binary search algorithm measures the exact byte length. If minor compression is needed, it applies a very gentle quality step so virtually no visual loss occurs.
Can I compress PNG images into 50KB JPG format?▼
Yes! Select JPEG as the output format. Transparent pixels are smoothly blended with a clean white canvas background before 50KB compression.
Is an internet connection required while compressing?▼
Once the page loads in your browser, all processing happens locally using JavaScript and Web Canvas. No image data is transmitted over the internet.
