To reduce the size of a JPEG file, you have several effective methods depending on your device and preferences:

On Windows

• Use the Photos app : Right-click the JPEG file, open with Photos, click the three dots menu, select "Resize image," enter new dimensions or adjust quality, then save the file

• Use Paint : Open the image in Paint, click "Resize," enter new horizontal or vertical values while maintaining the aspect ratio, then save the resized image

On Mac

• Use the Preview app : Open the image in Preview, go to Tools > Adjust Size, change width or height and/or resolution (72 PPI for digital use), then save the modified image

Using Photoshop

• Open the image in Photoshop, go to Image > Image Size, adjust dimensions and resolution (72 PPI for web, 300 PPI for print), choose resampling method like Bicubic Sharper, then save the image

Online Tools

• Use online compressors like TinyIMG, TinyJPG, CompressJPEG, Smallpdf, ShortPixel, or Watermarkly. These tools allow you to upload JPEG files and reduce file size by compressing them without significantly losing quality. Some let you set quality levels or target file sizes and support batch processing

Key Tips for Reducing JPEG File Size

• Lower image dimensions (width and height).
• Reduce image resolution (PPI) for digital use.
• Adjust JPEG quality/compression level (around 80% quality balances size and visual quality).
• Use lossless or intelligent compression tools to maintain image clarity while reducing size.

By combining resizing and compression, you can significantly reduce JPEG file size for easier sharing, faster uploads, or saving storage space
