How can I compress an image to under 50KB or 20KB for online forms?

Choose the Target Size (Exact KB) option and enter your desired limit (e.g. 50KB). The optimizer calculates the ideal quantization to stay within the limit.

What is the difference between lossy and lossless image compression?

Lossless retains raw data saving 10-25%. Smart Lossy removes imperceptible pixel data, saving up to 85% with zero visible degradation.

How can I visually verify quality retention after compression?

Click the Compare button on any compressed card to inspect original vs compressed side-by-side using our split-screen slider.

Does compressing images improve website performance?

Yes, reducing image weights enhances LCP (Largest Contentful Paint), boosting Google Core Web Vitals and overall user retention.

Image Compression — Frequently Asked Questions

Key insights about file reduction, target KB, and preserving photo clarity.

Choose the "Target Size (Exact KB)" option in Step 2, and enter 50 (or 20). Our algorithm uses intelligent multi-pass quantization to guarantee the final file size stays under your specified threshold while keeping details crisp.

Lossless compression removes invisible metadata without touching pixels, reducing size by 10-25%. Smart Lossy compression (used by our Balanced mode) removes imperceptible color data that the human eye cannot detect, saving 70-85% in file size with zero visible loss.

After compression, click the "Compare" button on any result card. This opens our interactive Split Slider modal where you can slide left and right to inspect the Original vs Compressed image side-by-side.
