Compress JPG Online

JPG compression can reduce file sizes by 50-90% depending on the original image and quality settings. Photos with lots of detail compress especially well, often achieving 70-80% reduction at quality 80.

JPG uses lossy compression, so some quality is lost. However, at quality settings of 75-85%, the difference is virtually imperceptible to the human eye while achieving significant file size savings.

For most use cases, 75-85% quality offers the best balance between file size and visual quality. For web images, 80% is ideal. For print or professional work, use 90-95%.

Yes, completely free with no limits. All processing happens in your browser—your images are never uploaded to any server.

Upload the image, press Compress, and read the compressed size shown next to the preview. If it is still above your limit, drag the quality slider down and compress again. Each pass reports the new size in KB, so you can stop as soon as you are under 100KB, 50KB, or 20KB. For a large photo, also set Max Width to 1024px or 800px, which usually cuts more weight than quality alone.

Upload forms for job applications, visas, and government portals normally cap images at 100KB to 500KB, and phone photos are several megabytes. Compressing to quality 60-70 with Max Width set to 1200px brings a typical phone photo under 200KB while still being readable on screen.
