Quick answer
How do you reduce an image file size without losing quality?
Upload your JPEG, PNG or WebP image (25 MB maximum), choose a compression quality, then download the result. A quality around 75%, the default setting, cuts the file size noticeably with little visible loss on screen. Compression runs in your browser, and the tool shows the size before and after along with the percentage reduction achieved.
About the Image Compression
What is it?
The image compressor reduces the file size of your JPEG, PNG and WebP files without perceptible loss of visual quality, directly in your browser.
Why use it?
Loading speed is a Google ranking factor and a major conversion factor. An unoptimized image can weigh several MB and significantly slow down your site.
How does it work?
Import your image, adjust the compression level and download the compressed file. All compression happens locally - your images never transit through our servers.
Usage tips
- For the web, aim for under 200 KB per content image, under 100 KB for thumbnails
- JPEG is ideal for photos, PNG for images with transparency
- Combine compression and resizing for maximum gain
- Images are the primary cause of slowness on most e-commerce sites
- Your files never leave your device - 100% private compression
