What is the Image Compressor & Optimizer?
The Image Compressor & Optimizer is a free online tool for reducing image file sizes directly in your browser. It supports batch PNG, JPG, and WebP compression with a live quality slider, before-and-after previews, original-to-optimized size reporting, and one-click downloads. SVG files are optimized too, with redundant metadata, comments, editor attributes, whitespace, and excess numeric precision removed from the markup. The tool is designed for faster websites, smaller design exports, and cleaner assets without requiring signup, watermarks, or server uploads.
How to Use the Image Compressor
- Drag multiple PNG, JPG, WebP, or SVG files into the upload area, or click to select files.
- Adjust the quality slider to preview the compressed size and visual result.
- Choose Auto, WebP, or JPG output for raster images. SVG files remain optimized SVGs.
- Review each file's original size, optimized size, and savings percentage.
- Download a single optimized file or export the whole batch as a ZIP archive.
Use Cases
- Compressing website images to improve page speed and Core Web Vitals
- Reducing design exports before uploading them to CMS, ecommerce, or portfolio sites
- Converting heavy PNG screenshots and UI assets to smaller WebP files
- Cleaning SVG exports from design tools before using them in production code
Frequently Asked Questions
Are my images uploaded to graphic.so?
No. Raster compression uses the browser Canvas API and SVG cleanup runs locally in your browser, so your files stay on your device.
Which formats can I compress?
The tool accepts PNG, JPG, WebP, and SVG files. Raster images export as WebP or JPG, while SVG files remain SVG after metadata and markup optimization.
Can I download multiple optimized images at once?
Yes. You can download individual optimized files or export all processed files together as a ZIP archive.
