Drag and drop your images or click to browse. You can add multiple files at once.
Set quality level, output format, and maximum dimensions to your preference.
Preview the compressed images and download them individually or all at once.
Use our tool with a quality setting of 80-90%. This typically reduces file size by 50-70% while maintaining visual quality that's nearly indistinguishable from the original. For photos, JPEG format works best; for graphics with transparency, use PNG.
Lower the quality slider to reduce file size in KB. A quality of 60-70% usually gives a good balance. You can also resize the image by setting a maximum width, or convert to WebP format which offers the smallest file sizes.
Image compression reduces the file size of an image by removing unnecessary data. There are two types: lossy compression (like JPEG) removes some image data for smaller files, while lossless compression (like PNG) keeps all data but is less effective at reducing size.
To get a specific file size like 100KB, adjust the quality slider while watching the output size. Start at 70% quality and lower it gradually until you reach your target. For large images, also consider reducing the dimensions.
Yes, lossy compression (JPEG, WebP) removes some image data which can affect quality. However, at 70-90% quality settings, the difference is usually imperceptible to the human eye. For important images, use higher quality settings or PNG format.
WebP typically produces the smallest files while maintaining good quality - often 25-35% smaller than JPEG. JPEG is great for photos, PNG for graphics with transparency, and GIF for simple animations. Choose based on your image type.
Simply drag and drop multiple images onto our tool, or click to select multiple files (hold Ctrl/Cmd). All images will be compressed with the same settings, and you can download them individually or all at once as a ZIP file.
Yes, completely safe! All compression happens directly in your browser - your images are never uploaded to any server. This means your files stay private, and the tool works even offline once loaded.
For web use, compress images to 60-80% quality in JPEG or WebP format. Resize images to the maximum display size needed. A typical website image should be under 200KB. Use our tool to achieve optimal web-ready images.
Compressed images load faster, save bandwidth, improve website performance and SEO, reduce storage costs, and make sharing easier via email or messaging. Always compress images before uploading to websites or social media.
Image compression works by analyzing pixel patterns and removing redundant data. JPEG uses lossy compression that discards details the human eye barely notices. PNG uses lossless compression that finds patterns to represent data more efficiently.
For most uses, 70-85% quality offers the best balance of size reduction and image quality. For high-quality prints, use 90-95%. For web thumbnails or email, 60-70% is usually sufficient. Preview to find your ideal setting.
