Reduce Image File Size
What Does This Tool Do? Reduce photo file size without significantly compromising image quality.
Reduce Image File Size User Guide
Reduce file size by adjusting image quality and output format. Compare both file size and the clarity of text or product photos.
Sample Input and Results
Process the same photo at quality levels 82 and 65, then compare file sizes and the readability of small text. Quality 65 does not mean the file will be 65% of the original size.
How Calculations & Processing Work
Re-encodes the image in the selected format. File size depends on resolution, colors, image complexity, and format.
When Using the Results
The compressed result may be larger than the original, and transparency and metadata may change depending on the format. Use a copy intended for public sharing instead of sensitive originals, such as South Korean resident registration cards.
Image Editing Studio
Use the original preview to adjust cropping, dimensions, enhancements, and output format.
