❓ FAQ

What quality setting should I use?+

For web use: 70-80% quality is ideal. For social media: 80-85%. For print: 90-95%. 80% typically reduces file size by 60-70% with barely visible quality loss.

Does PNG compression work the same way?+

PNG compression converts PNG to a compressed JPEG internally. If you need to maintain transparency (alpha channel), use our Image Converter to convert to WebP which supports compression + transparency.

Why Optimize and Compress Images?

Images are typically the heaviest assets on any modern website. Large, unoptimized images slow down page load speed, which directly damages user experience, increases bounce rates, and lowers your Google search rankings. Google's search algorithms use Core Web Vitals (specifically Largest Contentful Paint) as a ranking signal, making speed critical. Our online Image Compressor helps you compress JPG, PNG, and WebP graphics by up to 80% without visible quality loss.

The Physics of Lossy vs. Lossless Compression

Understanding how compression works helps you choose the best settings for your assets:

Lossless Compression: Removes redundant metadata and internal file profiles without altering a single pixel of image data. Ideal for logos and vector graphics.
Lossy Compression: Safely discards subtle color variations and pixel groupings that the human eye cannot easily distinguish. This yields massive file size reductions (often 70-90%) with negligible visual difference, making it perfect for blog photos and banners.
Local Processing: Our tool uses WebAssembly to process images locally inside your browser. No files are uploaded, ensuring 100% data privacy and instant processing speeds.

FAQs on Image Compression

Will my image quality drop?

At 80% quality settings, the difference is practically invisible to the human eye, while the file size is often reduced by more than half.

Is WebP better than JPEG?

Yes. WebP is Google's modern image format, offering up to 30% better compression ratios than standard JPEGs at similar quality settings.

Are my private photos uploaded?

No. Your images are compressed locally in your web browser. Your data never touches our servers, keeping your graphics completely private.
