Image Compressor: Reduce JPG, PNG & WebP File Size

Compress JPG, PNG and WebP images in your browser: set quality, convert to WebP, limit the width and download one by one or as a ZIP. No upload, no sign-up.

Drop images here, paste from the clipboard, or

JPG, PNG, WebP, GIF, BMP or SVG. Files never leave your browser.

    How to compress images

    1. Drop one or more images on the box, paste one from the clipboard, or choose files.
    2. Pick an output format. "Same as original" keeps JPG and WebP and turns PNG into WebP, which is usually far smaller.
    3. Move the quality slider. Around 70–80% is a good balance for photos on the web.
    4. Optionally set a max width: resizing a 4000 px photo to 1600 px saves more than any quality setting.
    5. Download each image, or everything as a ZIP file.

    Tips for smaller images

    • Serve images at the size they are displayed. A hero image rarely needs to be wider than 2000 px.
    • Use WebP (or AVIF where supported) for photos; it is often 25–35% smaller than JPEG at the same quality.
    • Keep PNG for screenshots, logos and graphics with sharp edges and few colors.
    • If a compressed file comes out larger than the original, the tool keeps the original automatically.

    Smaller images load faster, improve Core Web Vitals such as LCP, and save mobile data. Need exact dimensions? Use the image resizer.

    All processing happens in your browser. Your images are never uploaded to a server, so the tool works with private photos and keeps working offline once the page has loaded.
