How the tool compresses to 20 KB
This page starts at 20,480 bytes. For an image above that limit, it searches JPEG quality first. If the result is still too large and resolution reduction is enabled, it tries smaller dimensions. The panel reports the size reached, including a warning when the target was missed.
Where compressing an image to 20 KB falls short
- The target is a ceiling, not a minimum-to-maximum range. It cannot check the other conditions in an application notice.
- JPEG encoding can soften detail. Inspect the downloaded result rather than treating a size badge as a legibility check.
- This tool uses 1024 bytes per KB. For a 20,000-byte ceiling, a 19KB setting is 19,456 bytes; still check the achieved result.
Questions about compressing an image to 20 KB
Will my exam portal accept this 20KB file?
The tool can report bytes and dimensions, but it cannot validate the portal’s rules. A target can be missed, and an under-target result may still have the wrong dimensions, format or appearance.
Why did the resolution change when I only wanted a smaller file?
Resolution reduction was enabled and the quality search could not meet the ceiling at the original dimensions. Turn that option off to keep the dimensions, accepting that the size target may be missed.
What happens if my photo still cannot reach 20KB?
The result shows the missed target and actual size. It remains downloadable, so check the warning before using it.
Are ID photos sent to a server for this compression?
No. File decoding and compression run in this browser tab. This describes how the tool handles the file; it does not certify a document’s suitability for an official submission.
