Open Image CompressorHow to Compress Images Online
Compressing images with CompresslyPro takes seconds. Follow these three simple steps:
- Upload your image. Drag and drop a JPG, PNG, WebP, or GIF file (up to 20 MB) into the compressor — or click to browse your files. You can also paste an image directly from your clipboard.
- Adjust the quality slider. Set the compression level from 10% (maximum compression) to 90% (maximum quality). The default of 50% works well for most images — reducing file size by 60–80% with virtually no visible quality loss.
- Download your compressed image. Preview the before/after comparison using the built-in slider. When you're satisfied, click Download to save the compressed file. You can also copy the compressed image to your clipboard.
Why Compress Images?
Image compression is essential for web performance, email attachments, and storage efficiency:
- Faster websites. Images account for 42% of the average web page's weight. Compressing them improves load times, Core Web Vitals scores, and Google search rankings.
- Smaller email attachments. Most email providers limit attachments to 20–25 MB. Compressing photos from 3–5 MB to under 500 KB means you can attach many more images.
- Save storage space. Whether you're storing images on your phone, cloud drive, or server, compressed images use significantly less space.
- Better user experience. Faster-loading images mean visitors see your content sooner and are less likely to leave your site.

Quality Settings Guide
Choosing the right compression quality depends on your use case:
- 80–90%: Archival quality. Minimal compression but nearly lossless results. Best for print or professional photography.
- 60–70%: Web hero images. Excellent quality with significant file size reduction. Ideal for above-the-fold content.
- 40–50%: General web use. The sweet spot for most images — 60–80% smaller with imperceptible quality loss.
- 20–30%: Maximum compression. Visible artifacts may appear but file sizes are extremely small. Useful for thumbnails or low-bandwidth scenarios.

Frequently Asked Questions
Is the image compressor really free?
Yes, 100% free with no limits. No signup, no watermarks, no hidden fees. Compress as many images as you want.
What's the maximum file size?
You can upload images up to 20 MB each. For larger files, we use chunked uploading to ensure reliable transfers even on slower connections.
Can I compress images to a specific file size?
While you can't set an exact target file size, adjusting the quality slider gives you precise control. Quality 40–50% typically produces 100–300 KB files for standard photos. The result shows the exact compressed size before downloading.
Does compression remove EXIF metadata?
Yes, the compression process strips EXIF metadata (camera info, GPS coordinates, timestamps) from your images, which also contributes to smaller file sizes and better privacy.
