Frequently Asked Questions

How much can I compress a JPG without losing quality?

Typically 50-70% file size reduction with minimal visible quality loss. JPG compression is 'lossy' but our algorithms preserve important details while removing redundant data. For web use, 80% quality setting is usually perfect.

What's the difference between JPG and JPEG?

No difference - they're the same format. 'JPG' is the 3-letter file extension used on Windows, while 'JPEG' is the full name. Our tool handles both .jpg and .jpeg files identically.

Should I compress JPGs that are already compressed?

Be careful with re-compression. If your JPG is already optimized (under 500KB for web photos), further compression may degrade quality noticeably. Use our quality preview to check before downloading.

Can I compress JPG images in bulk?

Yes! Upload multiple JPG files at once and we'll compress them all with the same settings. Perfect for optimizing entire photo albums or website image folders.

Will compressing JPGs affect print quality?

For web/screen viewing, compressed JPGs look identical. For high-quality printing, keep original uncompressed files and only compress copies for digital use.

How does JPG compression work technically?

JPG uses DCT (Discrete Cosine Transform) to analyze image blocks and remove data the human eye can't perceive. Our tool optimizes this process for maximum compression with minimal quality loss.

What quality setting should I use for different purposes?

Web/social media: 80-85% quality. Email attachments: 70-80%. Thumbnails: 60-70%. Professional portfolios: 90-95%. The key is testing what looks good for your specific use case.

Pro Tips

  • Start with the highest quality original - you can't add quality through compression
  • For web use, aim for 200-500KB per image for optimal loading speed
  • Use 'Progressive JPEG' encoding for better perceived loading on slow connections
  • Crop unnecessary areas before compressing to maximize quality of important parts
  • For product photos, maintain higher quality (85-90%) to show fine details
  • Batch compress entire folders to maintain consistent quality across your site
  • Always keep uncompressed originals in case you need higher quality later
  • Test compressed images on mobile devices - they often show compression artifacts more clearly
