How much can I compress an image?

Results vary by image content, but JPG images are often reducible by 50–70% with minimal visual difference at 75–85% quality.

Can I compress multiple images at once?

Yes! The compressor supports multi-file upload so you can compress a batch of images in one go.

What formats are supported?

PNG, JPG/JPEG, and WebP are all supported.

What quality setting should I use for websites?

75–80% is the standard recommendation for web images. This typically cuts file size in half with no visible difference on screen.

Will compressing make my image blurry?

At 70% quality or above, compression artifacts are generally invisible to the naked eye. Going below 60% may introduce visible blurring or blockiness.

Does compressing a PNG make it lossy?

PNG compression is always lossless — reducing the quality slider for PNG affects the compression algorithm level, not visual quality. For lossy PNG compression, convert to JPG or WebP instead.

Why Use Image Compressor?

Large images are the single biggest cause of slow websites. Studies show that 53% of users leave a page that takes longer than 3 seconds to load, and images often account for 60–80% of a page's total weight. Compressing your images before uploading them to your website, CMS, or social media significantly improves loading speed, reduces hosting bandwidth costs, and can improve your Google PageSpeed score. Our compressor keeps your images looking sharp while cutting file sizes by 50–70% — a difference your visitors will notice immediately.
