Image Compressor

What is Image Compressor?

Image Compressor reduces the file size of images directly in your browser by adjusting output quality and format. No upload to a server  Eyour images are processed locally using the browser's Canvas API.

How to use

1. Click Choose Image and select a JPEG, PNG, or WebP file.
2. Adjust the quality slider (lower = smaller file, less detail).
3. Optionally select an output format (JPEG, WebP).
4. Click Compress and download the result.

Notes

• JPEG and WebP use lossy compression. Some image quality is lost at lower settings.
• PNG compression is lossless  Eswitching a PNG to WebP may give better size reduction.
• WebP typically produces 25 E5% smaller files than JPEG at the same visual quality.
• Compression is done in your browser. Images are never sent to a server.

FAQ

What quality setting should I use?

80 E5% quality is a good starting point for web use  Eit produces noticeably smaller files with minimal visible quality loss. Go lower for thumbnails or background images where fine detail matters less.

Should I use JPEG or WebP?

WebP is supported by all modern browsers and typically produces smaller files. Use JPEG for maximum compatibility with older systems or when WebP support is uncertain.

Does compression affect image dimensions?

No. This tool compresses quality only, not dimensions. Use the Image Resizer tool to change width and height.
