Questions about jpeg compressor
What JPEG quality should I use?+
A quality of 75–85% is a strong starting point for web photos. Use the preview to check fine detail before downloading.
Can I compress JPEG to an exact size?+
Choose Target Size and enter the maximum KB. CompressMint searches for the best quality that fits and may reduce dimensions when necessary.
Are my JPEG photos uploaded?+
Yes. CompressMint processes images locally in your browser. Your photos are not uploaded to our servers, and refreshing the page clears the working session.
