Image Compressor
Compress and reduce image file size directly in your browser. No upload to any server.
What is this tool?
An image compressor is a free browser-based tool that reduces the file size of JPG, PNG and WEBP images without uploading them to any server. Compression happens entirely in your browser using advanced algorithms — your images never leave your device, ensuring complete privacy.
How to Use
Common Uses
Compress images before uploading to WordPress, Shopify or any website to improve page load speed and Core Web Vitals scores.

Frequently Asked Questions
Does image compression affect quality?
Lossy compression (JPEG) reduces file size by removing some image data, which can slightly reduce quality at high compression levels. The quality slider lets you find the right balance. PNG uses lossless compression with no quality loss.
What is the difference between lossy and lossless compression?
Lossy compression (JPEG) permanently removes some image data to achieve smaller files. Lossless compression (PNG, WebP) reduces file size without any data loss — the image is perfectly reconstructed on decompression.
Is WebP better than JPEG?
WebP typically achieves 25–34% smaller file sizes than JPEG at equivalent visual quality. WebP also supports transparency like PNG. It is supported by all modern browsers.
Are my images uploaded to your servers?
No — all compression happens directly in your browser. Your images are never sent to FixForge servers, ensuring your photos and documents remain completely private.
