In the digital age, high-resolution images are essential for engagement, but they often come with massive file sizes that slow down websites and eat up storage. Our lossless image compressor is designed to solve this problem. By using advanced browser-side algorithms, we allow you to compress png and jpg without losing quality, ensuring your photos look crisp while being significantly lighter.
Website speed is a critical factor for both user experience and SEO. Large images are the primary cause of slow page loads. When you use a tool to shrink file size, you reduce the data transfer required for a visitor to view your page. Unlike lossy compression, which can leave artifacts and blurriness, our lossless approach maintains the integrity of every pixel. This is particularly important for logos, infographics, and professional photography where detail matters.
By optimizing your assets, you can improve your Core Web Vitals and provide a smoother experience for mobile users on limited data plans. If you need to further adjust your images, you might also find our Image Size Reducer helpful for specific dimension adjustments.
Our tool operates entirely within your browser. When you upload a file, we use the HTML5 Canvas API to re-encode the image. For JPEGs, we apply a high-fidelity quantization table that removes imperceptible data. For PNGs, we strip unnecessary metadata chunks (like EXIF data and color profiles) that don't affect the visual output but add to the file weight.
Lossy compression (like standard JPEG saving) discards data to achieve the smallest possible size, which can lead to "blocky" images. Lossless compression, on the other hand, focuses on efficiency without sacrificing clarity. If you are a photographer or a designer, lossless is the gold standard. It allows you to reduce mb to kb while keeping your portfolio looking professional.
To get the best results, always start with the highest quality original. Compress your images as the final step before uploading them to your website or social media. If you are working with web-specific formats, consider converting your files to WebP for even better compression ratios without quality loss.
No, there are no limits! Since the tool runs locally in your browser, you can compress as many images as you like without any daily restrictions or subscriptions.
If you upload a PNG with transparency, our compressor will preserve the alpha channel, ensuring your transparent backgrounds remain intact.
We currently support files up to 10MB. For larger files, we recommend resizing the dimensions first to ensure optimal performance in the browser.
