Compress Image to 20KB – Questions & Answers

Will my image look blurry when compressed to 20KB?
Our algorithm searches for the highest possible visual quality that remains strictly under 20,480 bytes. If your original image is large, it may slightly downscale the pixel dimensions so details stay sharp without pixelated compression artifacts.
Is it safe to compress sensitive signatures or IDs to 20KB here?
Yes, 100%. Exact Image Resizer runs entirely on your local device via Web APIs. Your files are never uploaded to any server or cloud database.
Why does the tool convert PNG to JPG when targeting 20KB?
PNG is a lossless compression format that ignores lossy quality sliders in browsers. To reach a tiny target like 20KB, JPEG or WebP compression is essential.
What should I do if my portal asks for between 10KB and 20KB?
Setting 20KB in our engine guarantees the output file will be at or just below 20KB (typically around 18KB–19.8KB), perfectly clearing the requirement.
