About the Compress Image Tool

Frequently Asked Questions

How much can I compress an image without losing visible quality?+
For JPG and WebP, reducing to 70-80% quality typically produces a file 60-80% smaller with no perceivable quality loss on screens. PNG uses lossless compression that preserves every pixel.
What is the difference between lossy and lossless compression?+
Lossy compression (JPG, WebP) permanently removes some image data to achieve smaller files. Lossless compression (PNG) reorganizes data without any quality loss. For photos, lossy is usually fine; for logos with text, use lossless.
Can I compress multiple images at once?+
Currently you compress one image at a time to give you full control over quality preview. The entire process takes under 5 seconds per image.
Will compressing an image change its dimensions or format?+
No. Compression only reduces file size. The output image has the same pixel dimensions and format as the original.
