JPEG is the most common photo format but files can be unnecessarily large. This tool compresses JPG images by 50-80% with barely noticeable quality difference — all in your browser, no upload needed.
JPG photos from cameras and phones are often 3-10MB. For web, email, and social media, you rarely need more than 200-500KB. Compression bridges this gap.

Frequently Asked Questions
What is the best quality for JPG compression?
80% is the sweet spot for web use — 60-70% size reduction with imperceptible quality loss. For print: 90-95%. For thumbnails: 60-70%.
Does JPG compression lose quality?
Yes, JPEG is lossy compression. But at 80%+ quality, the loss is invisible to human eyes on screen. Each re-compression adds more loss, so compress from the original.
Can I compress JPG without any quality loss?
Not with standard JPEG. For truly lossless compression, convert to PNG or WebP lossless. But JPEG at 90-95% is visually lossless.
