Many government portals, visa applications, exam registration forms, and online job applications require you to upload a photo that is "under 20KB" or "exactly 20KB." This is a real pain point — most photos straight from your phone are 2-5MB, which is 100-250× too large. Here's how to compress your JPEG to under 20KB while keeping it recognizable.
Step-by-Step: Compress JPEG to 20KB
- Open the Image Compressor
- Upload your JPEG photo
- Start with quality around 30-40% — this is much lower than normal web compression
- Check the output file size. If still over 20KB, lower quality further
- If the image becomes too blurry, resize it to smaller dimensions first (try 300-400px wide), then compress
Why 20KB Is So Hard
20KB is an extremely small file size for an image — about the size of a short email. Most photos need to be both heavily compressed AND reduced in resolution to reach this target. It's a two-step process: resize to minimal dimensions, then compress aggressively.
Pro Tips for Hitting the 20KB Target
- Resize first. Use our Image Resizer to reduce the photo to passport-photo size (about 300×400 px) before compressing
- Use JPEG format. JPEG compresses photos much smaller than PNG
- Quality 20-30% is normal for 20KB targets. It won't look great, but it's what these forms require
- Preview before downloading. Our compressor shows before/after side by side — make sure it's still usable
