How to compress an image online without quality loss?
Image compression reduces file size by 50 to 80% while preserving visual quality. FileSwiftly optimises your JPEG, PNG, WebP and GIF files directly in your browser with no installation required. The result: lighter images that load faster on the web.
JPEG, PNG and WebP compression
For JPEG photos, a quality level between 75 and 85% is the standard used by Google, Facebook and Twitter — visually indistinguishable but 60–75% lighter. For PNG images (logos, screenshots), lossless compression reduces size by 20–40% without changing a single pixel. The WebP format achieves up to 30% additional compression over JPEG at equivalent quality — ideal for modern websites.
Why optimise your website images?
Images account for an average of 60% of a web page's weight. Unoptimised images slow loading, hurt Google PageSpeed scores, and degrade user experience. Reducing image weight directly improves your SEO ranking, Core Web Vitals (LCP), and conversion rates.
Batch image compression with FileSwiftly Pro
The free plan compresses one image at a time. FileSwiftly Pro allows compressing up to 50 images simultaneously, exporting to WebP or AVIF, and accessing the REST API to automate compression in your development workflows.
FAQ
What quality setting should I use?
75–85% is optimal for most web uses. Below 60%, compression artifacts become visible in smooth areas.
Does compression change image dimensions?
No. Compression only reduces file weight, not dimensions (width × height). Use our Resize tool to change dimensions.
Which image formats are supported?
JPEG, PNG, WebP, and GIF as input. Output keeps the same format. Use our Image Converter to change formats.
