How to reduce image file size without losing quality (5 techniques)
Short summary
Three techniques significantly reduce image file size without quality loss: convert to WebP/AVIF formats (which save 25-60% vs JPEG), strip EXIF metadata to remove 50-200KB per image while protecting privacy, and size images to actual display dimensions rather than uploading 10x-oversized originals. Use target file-size constraints rather than guessing quality sliders for precise compression. All techniques are available in free browser tools requiring no sign-up.
