Supports JPG, PNG, WebP
How to Use the Image Compressor
Upload any image (JPG, PNG, or WebP) by dragging it into the dropzone or clicking to browse. Adjust the quality slider to control the compression level — lower values mean smaller files but reduced quality.
Compression Settings
- Quality Slider — Ranges from 1% (maximum compression) to 100% (original quality). A setting of 70–80% typically offers the best balance between file size and visual quality.
- Output Format — Choose JPEG for photos or WebP for modern browsers with better compression.
How It Works
The tool uses the HTML5 Canvas API to re-encode your image at the selected quality level. Everything runs entirely in your browser — your images are never uploaded to any server.
Frequently Asked Questions
How much can I reduce the file size?
Typical savings range from 30% to 80% depending on the original image and the quality setting you choose. Photos with lots of detail compress more than simple graphics.
Does compression reduce image dimensions?
No. The image compressor only reduces file size by adjusting encoding quality. The width and height of your image remain unchanged. Use the Image Resizer tool to change dimensions.
Which format gives the smallest file size?
WebP generally produces smaller files than JPEG at the same visual quality. However, JPEG has broader compatibility with older browsers and applications.
Is my image uploaded to a server?
No. All compression happens locally in your browser using the Canvas API. Your image never leaves your device.
What is the best quality setting?
For most photos, 70-80% quality provides excellent visual quality with significant file size reduction. For images where quality is critical, try 85-90%.
