FAQ
Will compression reduce image quality?
Depends on the quality setting. 100% is nearly lossless; 75-90% is hard to distinguish; below 50% shows visible blurring. WebP is smaller at the same quality.
What image formats are supported?
Input: JPG, PNG, WebP, GIF. Output: JPG, PNG, WebP. GIF output loses animation and keeps only the first frame.
Is there a size limit?
Theoretically unlimited, but constrained by browser memory. Single images should be under 20MB to avoid crashes.
