Compress images online for free with a live quality preview. Our image compressor uses the HTML5 Canvas API to re-encode JPG, PNG, and WebP files at the exact quality level you choose, reducing file size for faster websites, smaller email attachments, and quicker uploads to social media. Everything happens locally — your images never touch a server.
Drag and drop a JPG, PNG, or WebP file, or click to select one. The original file size is shown so you can compare.
Move the slider to balance file size against visual quality. Watch the preview update in real time and see the new size before saving.
When you're happy with the size/quality trade-off, click download. The compressed image keeps the original format.
Large images are the single biggest cause of slow websites. A page with 5MB of images loads three to five times slower than the same page with images compressed to 500KB total — and Google uses page speed as a ranking signal. Compressing your images is the fastest SEO win available.
Email providers like Gmail and Outlook reject attachments larger than 25MB. A handful of phone photos quickly hits that limit. Compressing them first lets you send the whole set in one email.
Unlike server-based compressors, this tool processes images in your browser. There's no upload wait, no privacy risk for personal photos, and no daily file count limit. Compress as many images as you need.
