Why Compress JPG Files?
Large JPG files slow down websites, get rejected by email attachments, and eat up storage. Compressing to under 200KB is standard practice for web images. Our tool uses advanced algorithms to reduce file size by 50–80% while keeping the image visually sharp.
Best Quality Setting for JPG Compression
- 80–85% - Best for web use: sharp images, small file size
- 70–75% - Good for email attachments and social media
- 60–65% - Aggressive reduction for very large photos
- 90–95% - Minimal compression, nearly lossless
Frequently Asked Questions
Does compressing a JPG reduce quality?
At 75–85% quality, the difference is invisible to the human eye. Only at very low settings (below 50%) does compression become visually noticeable.
Is my JPG uploaded to a server?
No. All compression happens in your browser using JavaScript. Your images never leave your device - they are 100% private.
What is a good JPG file size for a website?
Under 150KB for blog images, under 300KB for hero images. Google PageSpeed recommends images be compressed as much as possible without visible quality loss.
Can I compress multiple JPG files at once?
Currently this tool handles one file at a time. Batch compression is coming soon.
