Quick answer
Open the KitPadi Image Compressor, choose your JPG, PNG or WebP file, then reduce the maximum width and quality until the downloaded JPG is below your target. For a 100KB target, begin around 1200 pixels wide and 70–80% quality. For 50KB or 20KB, use a smaller width and lower quality, but inspect the text and face before submitting.
What 20KB, 50KB and 100KB mean
KB means kilobytes and describes the amount of storage used by the file. Pixel dimensions describe its width and height. They are related, but they are not the same: two 600 × 800 images can have very different file sizes because of format, detail and compression.
| Typical target | Useful starting point | Check carefully |
|---|---|---|
| 100KB | 1200px width, 75% quality | Faces and small writing |
| 50KB | 800px width, 60–70% quality | Edges, stamps and signatures |
| 20KB | 400–600px width, 45–60% quality | Whether the portal also requires exact dimensions |
These are starting points, not guarantees. A busy photograph normally needs more compression than a simple signature on a white background.
Compress the image step by step
- Keep a copy of the original image.
- Open the KitPadi Image Compressor and select the file.
- Set a sensible maximum width. Do not shrink below a portal’s required dimensions.
- Choose a moderate quality setting and preview the result.
- Download the compressed JPG and check its size in your phone or computer file details.
- If it is still too large, reduce width or quality a little and repeat.
- Zoom in on important details before uploading.
Best approach: make small reductions rather than jumping straight to the lowest quality. This usually preserves more useful detail.
If the image is still too large
Crop empty space around the subject, reduce the pixel dimensions, or convert a detailed PNG to JPG. Screenshots and scanned pages often contain more pixels than an application portal needs. However, never crop away document edges, official stamps or required head-and-shoulder space.
Common mistakes to avoid
- Confusing 100KB with 100MB. One megabyte is roughly 1,000 kilobytes.
- Checking only the filename instead of the downloaded file size.
- Repeatedly compressing an already-compressed copy; always return to the original when possible.
- Ignoring exact pixel dimensions specified by the receiving portal.
- Submitting a blurred signature, face or certificate simply because the file passes the size limit.
Frequently asked questions
Can every image be reduced to exactly 20KB?
Most images can be made very small, but the result may become unsuitable. The real goal is to stay below the limit while keeping required details readable.
Does KitPadi upload my image?
The compressor is designed to process the image in your browser. You should still avoid using public devices for sensitive documents.
Should I choose JPG or PNG?
JPG is usually smaller for photographs. PNG is useful for sharp graphics and transparency, but can be much larger.
