Click the upload area or drag and drop your image file into the tool. Supported formats include JPEG, PNG, and WebP images of any resolution.
Adjust the quality slider to set your desired compression level. Lower values produce smaller files but may introduce visible quality loss, while higher values preserve quality at the cost of larger file sizes.
Preview the compressed result side by side with the original to visually compare quality. The tool displays both file sizes so you can see exactly how much space you are saving.
Download the compressed image when you are satisfied with the quality-to-size ratio. The output file is ready for use on websites, emails, or social media.
Website page load speed is a critical ranking factor for search engines. Compressing images before uploading them to your website can reduce page load times by 40-70%, directly improving your SEO rankings and user experience.
Social media platforms, email services, and content management systems often impose file size limits. Compressing images ensures your visuals meet upload requirements without sacrificing clarity or visual appeal.
All image processing happens directly in your browser. Your photos, screenshots, and sensitive images are never uploaded to any server, guaranteeing complete privacy. This makes the tool safe for medical images, personal photos, and confidential documents.
Reduced image sizes mean lower bandwidth costs for website operators and faster downloads for visitors on slower connections. A single page with properly compressed images can save megabytes of data transfer per visitor.
Unlike many online compressors that add watermarks, limit file sizes, or require paid subscriptions, this tool is completely free with no restrictions on the number of images you can process.
For photographs, JPEG compression at 75-85% quality usually provides an excellent balance between file size and visual quality that most viewers cannot distinguish from the original.
PNG images with large areas of solid color compress very well. Consider converting complex photographs from PNG to JPEG for significantly better compression ratios.
WebP format often produces files 25-35% smaller than JPEG at equivalent visual quality. If your target platforms support WebP, prefer this format for maximum compression.
Always keep an original copy of important images before compressing. Compression is a lossy process for JPEG and WebP, meaning quality cannot be restored once reduced.
For JPEG images, you can typically reduce file size by 60-80% with minimal visible quality loss using a quality setting of 70-85%. The exact savings depend on image content: photographs retain quality well at lower settings, while images with text or sharp edges may need higher quality. PNG images can be reduced 30-50% through lossless optimization.
Yes, all image compression happens entirely in your browser using client-side JavaScript and the HTML5 Canvas API. Your images never leave your device, are never uploaded to any server, and are never stored anywhere. This makes the tool completely safe for personal photos, sensitive documents, and confidential business images.
WebP is currently the best format for web images, offering 25-35% smaller files than JPEG at equivalent quality, with support from all major browsers. JPEG remains excellent for photographs when broad compatibility is needed. PNG is ideal for images requiring transparency or those with text, logos, and sharp edges where lossless compression is important.
Absolutely. Google considers page speed a ranking factor, and images are typically the largest contributors to page size. Properly compressed images can improve your Core Web Vitals scores, reduce Largest Contentful Paint (LCP) times, and lead to better search engine rankings. Google recommends keeping total page weight under 1.6MB, with images accounting for a significant portion.
The current version processes one image at a time for maximum quality control. For each image, you can adjust the quality slider and preview the result before downloading. This approach ensures you get the optimal compression level for each individual image based on its content and your quality requirements.
Since processing happens in your browser, the maximum size depends on your device's available memory. Modern devices with 4GB or more RAM can typically handle images up to 50 megapixels (approximately 8000x6000 pixels) without issues. For very large images, processing may take a few seconds longer but will complete successfully on most modern devices.
