Image Compressor
Compress images for websites, email, forms, blogs, product pages, and social media. Upload an image, choose quality and size settings, compare the before-and-after file size, and download the optimized version.
What does image compression do?
Image compression reduces file size so images load faster and are easier to upload, email, store, and publish. The goal is to keep the image visually useful while removing unnecessary file weight. This can help websites feel faster, reduce bandwidth use, and make image-heavy pages easier to browse.
For websites and SEO
Large images can slow down pages, especially on mobile connections. Compressing banners, blog images, product photos, and thumbnails can improve page experience and reduce loading time.
For forms and email
Many application forms, portals, and email platforms have file size limits. Compressing an image can help it fit upload limits without manually resizing it in design software.
For social media and ecommerce
Product photos and social media images should be sharp but not unnecessarily heavy. A balanced quality setting can keep images clear while reducing file size.
How to choose compression quality
A quality setting around 80% is often a good starting point for general web images. If the file is still too large, reduce the quality or lower the maximum width and height. If the image contains text, logos, product details, or important fine lines, keep quality higher and preview the result before publishing.
JPG, PNG, and WebP compression
JPG is usually good for photos. PNG is useful for transparent graphics, screenshots, and logos, but it can be larger. WebP often provides strong compression for web use, but you should confirm compatibility with your website, app, or upload platform before converting every image.

Image Compressor FAQ
Will compression reduce image quality?
Some quality reduction may happen, especially at lower settings. Use the preview and compare the output before publishing.
What quality setting should I use?
Start around 80% for websites. Use higher quality for product details and lower quality when file size matters more.
Can I convert images to WebP?
Yes, choose WebP as the output format. Confirm your target platform supports WebP before uploading.
Why is my PNG still large?
PNG files can remain large because they preserve transparency and sharp edges. Try WebP or JPEG if transparency is not needed.
