How to Use Image Compressor
-
1. Upload Your Image
Drop a JPEG, PNG, WEBP, or SVG file onto the drop zone, or click Browse Files. You can compress multiple images in sequence.
-
2. Adjust Quality Settings
Use the quality slider to balance file size against visual fidelity. For SVGs, toggle specific SVGO optimizations to control what gets stripped.
-
3. Download the Compressed File
The compressed output and size savings percentage appear instantly. Click Download to save the optimized file.
The Technical Details
This interactive web utility provides fast, reliable, and completely private data transformations. In modern workflows, quick formatting, conversions, or estimations are essential. By running all logic entirely in your browser with client-side JavaScript, this tool guarantees that your data never leaves your machine. This approach delivers maximum performance and absolute data privacy, as no information is ever sent to a server.
Frequently Asked Questions
How much can the file size be reduced?
Results vary by image. JPEGs at quality 75–80 typically lose 40–70% of their original size with minimal visible difference. SVG compression can be even higher for complex files.
Is compression lossless or lossy?
JPEG and WEBP compression is lossy — lower quality means smaller files but more artifacts. PNG and SVG compression uses lossless or structure-only optimizations.
Which formats are supported?
JPEG, PNG, WEBP, and SVG. Each format uses format-appropriate compression: Canvas re-encoding for raster images and SVGO for vector files.
Are my images uploaded to a server?
No. All compression runs in your browser. JPEG, PNG, and WEBP use the HTML5 Canvas API; SVG uses the SVGO library loaded locally. Nothing leaves your device.
