Image Compressor — Reduce File Size Without Quality Loss
Compress PNG, JPG, and WebP images right in your browser. Adjust quality, resize, and convert formats to dramatically reduce file size — perfect for faster websites, smaller email attachments, and quicker uploads.
How it works
- 100% client-side: Your images never leave your browser. No upload, no privacy concerns.
- Adjustable quality: Slider from 10% to 100% lets you balance file size and image quality.
- Format conversion: Convert to JPEG, PNG, or WebP. WebP typically saves 30–50% over JPEG at the same quality.
- Resize on the fly: Set a max width to scale images down (essential for web).
- Batch processing: Drop multiple files at once.
When to use which format
- JPEG — photographs, complex images with many colors
- PNG — logos, icons, screenshots, images needing transparency
- WebP — best compression for web (supported by all modern browsers since 2020)
Typical savings
A 4 MB JPEG photo at 95% quality can usually be reduced to 800 KB at 75% quality with no visible difference. A PNG screenshot can drop from 2 MB to 200 KB by converting to WebP.
Privacy
All compression happens in your browser using the Canvas API. We never see, store, or transmit your images.
