How to use the image compressor
This image compressor is created for first-time users who want to shrink picture files without losing visual quality. Upload a JPG, PNG, or WebP image and choose how much compression you need. The image compressor will then reduce the file size while keeping the image looking good.
If you are new to an image compressor, focus on the preview and the size savings the tool shows. This makes it easy to understand how much space you can save before you download the final image. The image compressor is designed to keep the workflow simple and fast.
You can use this image compressor whenever you need smaller images for web pages, email attachments, or sharing. It is a convenient online tool for anyone who wants a quick and user-friendly way to reduce image size.
About this tool
Optimize JPG, PNG, and WebP images directly in your browser. Tweak compression quality, resize by percentage or exact dimensions, and download smaller files after previewing the savings. Large, unoptimized images are a major cause of slow website loading times, which hurts both user experience and search engine rankings. Whether you are preparing images for a website, optimizing photos for email, or reducing storage costs, image compression is essential.
Our image compressor tool handles JPG, PNG, WebP, and other common formats. Adjust compression quality with an easy slider—higher quality means larger file size, while lower quality reduces file size but may show artifacts. The preview window shows the original image alongside the compressed version so you can see the quality tradeoff before downloading.
Beyond compression, the tool also resizes images by percentage or exact dimensions (width × height in pixels). This is useful for creating thumbnails, fitting images to specific layouts, or reducing dimensions for faster uploads and downloads.

Download optimized image
Click Download to save the compressed/resized image to your computer. The file size will be significantly smaller than the original.
Frequently Asked Questions
What's the difference between compression and resizing?
Compression reduces file size while keeping dimensions the same by removing visual redundancy. Resizing changes dimensions (width/height) which also reduces file size. Use both together for maximum optimization.
Will compression affect image quality?
Yes, but you control how much. High compression = small file + visible quality loss. Low compression = larger file + barely visible quality loss. Preview the result before downloading to find your ideal balance.
What image formats are supported?
The tool supports JPG, PNG, WebP, GIF, and BMP. Different formats have different compression characteristics—JPG is best for photos, PNG for graphics with transparency, and WebP offers excellent compression.
Can I batch compress multiple images?
The current version processes one image at a time. For batch compression, you can compress multiple images individually by repeating the process, or use command-line tools like ImageMagick.
Is my image data private?
Yes, completely. All image processing happens in your browser. Your images are never uploaded to servers or stored anywhere. Close your browser and the image is gone—perfect for privacy-sensitive photos.
