Reduce image file sizes by up to 80% without losing visible quality. Fast, private, and runs 100% in your browser.
Large, uncompressed images are the #1 cause of slow websites and high mobile bounce rates. Our free online image compressor reduces PNG, JPG, and WebP file sizes instantly inside your browser — boosting your website's Core Web Vitals without sacrificing visual clarity.
According to Google web performance studies, over 50% of mobile users abandon a website if it takes longer than 3 seconds to load. Massive 4 MB to 8 MB raw photos from cameras and smartphones bottleneck network bandwidth, causing poor Largest Contentful Paint (LCP) metrics and lower search rankings.
By compressing images before uploading them to WordPress, Shopify, Webflow, or custom web apps, you dramatically reduce data payloads, slash server hosting bandwidth costs, and provide your visitors with instantaneous page loads.
| Format | Best Used For | Transparency | Typical Compression Ratio |
|---|---|---|---|
| JPEG / JPG | Photographs, complex gradients, blog heroes | No | 60% – 85% file reduction |
| PNG | Logos, UI icons, screenshots, graphics with text | Yes (Alpha channel) | 40% – 70% file reduction |
| WebP | Modern web graphics, e-commerce, universal photos | Yes (Full support) | 70% – 90% file reduction (25% smaller than JPG) |
Optimize your entire visual asset pipeline with our suite of free browser utilities:
Our tool applies intelligent lossy compression using the browser's native Canvas rendering engine. It removes redundant image metadata (EXIF data, camera profiles, timestamp tags) and optimizes color frequency tables. By fine-tuning quantisation matrixes at a 75–85% quality threshold, it slashes file size by up to 80% while retaining crisp, high-resolution details indistinguishable to the human eye.
For web banners, blog hero images, and e-commerce product photos, a compression quality setting between 75% and 82% is ideal. This delivers maximum byte reduction (often taking a 3 MB photo down to ~200 KB) while keeping images sharp on Retina and 4K displays.
Yes. Images account for over 60% of total web page weight. Heavy uncompressed photos severely degrade Largest Contentful Paint (LCP) and PageSpeed Insights scores. Compressing your images accelerates page loading, reduces bounce rates, and directly improves mobile search rankings in Google.
Yes! Our compressor supports transparent PNG and WebP images. It optimizes alpha channels and compresses RGB color data without creating ugly black or white artifact borders around transparent areas.
No. Unlike other online converters that upload your media to third-party cloud servers, our image compressor operates 100% client-side inside your browser sandbox. Your photos, private documents, and screenshots are never transmitted over the internet.
You can compress images up to 25 MB and 8000×8000 pixels. Because processing occurs directly in your local hardware memory, there are no artificial limits, hourly quotas, or premium watermarks.
Instant, browser-local utilities to streamline your digital workflows.
