Image Compressor
Free online image compression tool, processed locally no upload
Why Compress Images?
Large images slow down page loading, increase bandwidth costs, and hurt SEO rankings. Image compression reduces file size while maintaining acceptable visual quality. This is especially important for websites, mobile apps, and email attachments where every kilobyte matters.
How to Compress Images
Upload an image (JPEG, PNG, or WebP). Adjust the quality slider — lower values produce smaller files but may introduce artifacts. Set a maximum width to resize large images. Click Compress and download the result.
▶What quality level should I use?
For web images, 70-85% quality is usually the sweet spot — significant file size reduction with minimal visible quality loss. Below 60%, artifacts become noticeable.
▶Does compression reduce image dimensions?
Only if you set a maximum width. Otherwise, the pixel dimensions remain the same and only the file size is reduced through lossy compression.
▶Is this lossy or lossless compression?
This tool uses lossy compression (adjustable quality). For lossless compression, use PNG format which compresses without quality loss but may produce larger files.
