Reduce Image Quality
Upload any JPG, PNG, WebP, or GIF image to process instantly in your browser.
Choose Image FileLower image quality and byte size with precision compression sliders to meet exact file weight constraints for portal uploads and emails.
Upload any JPG, PNG, WebP, or GIF image to process instantly in your browser.
Choose Image FileAdjust compression ratio from 5% to 95% with live byte-size feedback.
Inspect original vs compressed image clarity before saving.
Safe for sensitive identity documents, passports, and utility bills.
Rapidly tune and save multiple images in succession.
The Image Quality Reducer applies discrete cosine transform (DCT) quantization scaling in your browser.
By zeroing out high-frequency spatial luminance and chrominance coefficients according to the selected quality factor, high-frequency noise is eliminated while structural edge clarity is preserved.
The resulting compressed stream is packaged into standard JPEG or WebP files ready for instant download.
Reduce identity photos to meet strict 200KB upload limits.
Downsize signature scans and passport photos to sub-50KB portal requirements.
Optimize mobile web assets for 2G/3G network performance.
Shrink multi-megabyte photo sets to fit standard 10MB email attachment quotas.
Upload your photo, set the quality slider to around 60%-70%, and monitor the estimated file size. If necessary, combine with downscaling.
No. The pixel width and height remain identical; only the compression quantization matrix is adjusted.
Yes. Softnag operates 100% inside your browser with zero cloud storage or server processing.
Many enterprise and government systems limit upload sizes to conserve server storage and bandwidth across millions of applicants.
Yes. You can re-encode PNG files to optimized lossy WebP or JPEG formats to achieve massive size reductions.
Between 70% and 85% provides significant size reduction with virtually indistinguishable visual difference.
