    About the Image Compressor tool

    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.

    How to use the Image Compressor

    1. Step 1: Upload your image

      Drag and drop a JPG, PNG, or WebP file, or click to select one. The original file size is shown so you can compare.

    2. Step 2: Adjust the quality slider

      Move the slider to balance file size against visual quality. Watch the preview update in real time and see the new size before saving.

    3. Step 3: Download the compressed image

      When you're happy with the size/quality trade-off, click download. The compressed image keeps the original format.

    Why use this Image Compressor?

    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.

    Frequently asked questions

    How much can I compress an image?
    Photos typically compress 60-90% with no visible quality loss at 75-85% quality. Screenshots and graphics compress less because they have less redundant data.
    What's the best quality setting?
    85% is a great default for photos — invisible quality loss with big file savings. Drop to 70% for very large reductions; stay at 90%+ for archival images.
    Does it support PNG?
    Yes. PNG compression uses a different algorithm (palette reduction and Canvas re-encoding) but achieves significant savings for screenshots and graphics.
    Will compressed images upload faster?
    Yes — proportionally to the size reduction. A 5MB photo compressed to 500KB uploads 10x faster on any connection.
