Why Use This Tool?

Page load speed is a Google ranking factor, and images are the most common cause of slow load times. Compressing a 3MB photograph to under 400KB with no perceptible quality loss can significantly improve Largest Contentful Paint (LCP) scores and reduce mobile data usage. All processing happens in your browser β€” no file is uploaded.

Frequently Asked Questions β€” Image Compressor

Common questions about this tool.

What quality level should I use?
0.65-0.75 for web and social media. 0.85+ for print-preview images. 0.50 for thumbnails.
Does compression affect my original file?
No. The tool creates a compressed version in memory β€” your original is never modified.
Why is the output always JPEG?
JPEG supports lossy compression for smaller sizes. PNG and WebP inputs are processed through the JPEG encoder.
Is my image sent to a server?
No. All processing uses the HTML5 Canvas API locally in your browser.
What is the maximum file size?
No hard limit, but very large images (50MB+) may slow the browser since processing is in-memory.

About Image Compressor

Image file size directly impacts website performance, email deliverability, and storage costs. A large uncompressed photograph can exceed several megabytes, causing web pages to load slowly on mobile networks. Image compression reduces file size by selectively discarding visual data the human eye is least sensitive to, while preserving the overall appearance. Start with quality 0.70 β€” this typically reduces file size by 40-70% while keeping the image visually indistinguishable from the original. Slide lower for social media thumbnails or higher for portfolio images.
