General

Heavy, unoptimized images are the number one cause of slow-loading websites. By compressing your images, you dramatically reduce the file size which speeds up page loading times. Faster loading times lead to better user experiences, lower bounce rates, and higher rankings in search engines like Google (Core Web Vitals).
Yes! WebP and AVIF are next-generation image formats that provide superior lossless and lossy compression compared to traditional JPEG and PNG formats. You can easily select WebP or AVIF from the format settings above before dropping your images.
Absolutely. Unlike traditional online tools that force you to upload files to their servers, this tool runs 100% locally in your browser. Your files are processed using your own device's memory and are never transmitted over the internet, making it entirely safe for private, client, or sensitive photos.
Yes, the tool is fully responsive and works natively on iOS and Android devices. Since modern mobile browsers (like Chrome and Safari) have robust processing capabilities, you can compress photos directly from your camera roll.
No, never. We do not alter your image visually other than the compression algorithms you select, and we definitely do not apply any watermarks or hidden branding to your converted files.

How does it work

Lossy compression is a method that significantly reduces file size by permanently removing minor visual information that the human eye cannot easily detect. This is standard for formats like JPEG and WebP. By intelligently stripping redundant color data and metadata, file sizes drop drastically while the image still looks practically identical to the original.
When you drop an image into the tool, we utilize the native HTML5 Canvas API. Your browser reads the image into its local memory, redraws it applying your chosen compression settings and resizing rules, and then packages it back into a downloadable file. This entirely skips the need for a backend server.
Formats like JPEG and PNG have universal support. WebP is currently supported by 97%+ of all browsers worldwide. AVIF is supported by all modern browsers (Chrome, Safari 16+, Firefox) but may not display on very old systems. For universal safety on modern websites, WebP is the recommended choice.
If an image is already heavily compressed, re-processing it (especially into lossless formats like PNG) can sometimes increase the file size due to format headers and canvas overhead. Additionally, converting a lossy JPEG to a lossless PNG will almost always result in a larger file without improving quality. If your file size increases, simply keep the original!
Yes. By default, drawing an image through the browser's Canvas API automatically strips out EXIF metadata, such as GPS location, camera model, and exposure settings. This is fantastic for both reducing the final file weight and protecting your privacy when publishing images online.

Web compressor

Yes! Because the processing happens locally on your own hardware rather than on an expensive cloud server, there are no server costs. We offer this tool completely free of charge with no hidden subscriptions or premium tiers.
You can drag and drop up to 20 images at a time. While there is no strict file size limit, remember that the tool uses your device's RAM to process the images. Dropping 20 massive RAW files might cause your browser to lag or crash, so we recommend batches of standard web images for the best experience.
Currently, if you upload an animated GIF, the tool will extract the first frame and convert it into a static image (like a JPEG or WebP). Full animated GIF optimization is highly complex for browser-side processing and is not natively supported yet.
For images containing text, sharp lines, or transparent backgrounds (like logos or illustrations), you should use PNG or WebP (with quality set high). JPEG is lossy and introduces "artifacts" around sharp edges, making text look blurry or pixelated.
