Frequently Asked Questions

How much can I compress an image?

It depends on the format and content. JPG photos typically compress by 50-80% at quality 80. PNG files compress by 20-40%. WebP and AVIF already use efficient compression, so gains vary.

Does compressing an image reduce quality?

Lossy compression (JPG, WebP, AVIF) does remove some data, but at quality 75-85 the difference is invisible to the human eye. PNG compression is lossless.

Which format gives the smallest file size?

AVIF produces the smallest files, followed by WebP, then JPG. PNG is the largest for photographs but ideal for graphics with transparency.

Can I compress images for email attachments?

Yes. Compress your photos to stay under Gmail's 25 MB or Outlook's 20 MB limit. Aim for quality 80 to get files under 1 MB each.

Are my images safe?

Yes. Files are processed on our server via HTTPS and automatically deleted after 1 hour. They are never shared or used for any other purpose.
