What is Compress Images?
Compression shrinks a file by removing redundant image data. Lossy compression (JPG, WebP) trims data for big savings; lossless compression (PNG) rearranges data with no quality change. A quality slider lets you balance size against sharpness.

Image Format Comparison
When you compress images, the format you export to changes the balance between quality and file size. Here's how the common formats compare:
| Format | Best for | Transparency | Typical file size |
|---|---|---|---|
| JPG | Photographs, complex images | No | Baseline |
| PNG | Logos, graphics, text | Yes | 2–5× JPG |
| WebP | Web images (modern) | Yes | 25–34% smaller than JPG |
| AVIF | Next-gen web delivery | Yes | ~50% smaller than JPG |
Frequently Asked Questions
How much can I compress an image?
It depends on content and format. JPGs often shrink 40–70% with no visible loss; PNGs drop 10–30% losslessly.
What's the difference between lossy and lossless?
Lossy discards some data and may slightly affect quality; lossless reduces size with zero quality loss but smaller savings.
Will compression hurt my image quality?
You control the level. The live preview helps you pick the sweet spot — typically 70–85% quality looks identical to the original.
Is online image compression safe?
Yes. It's 100% browser-based; your images never reach a server.
