- Each one is compressed to fit under 20KB.
- Download the resized files.
Why 20KB limits still exist
Some government portals, older exam boards and legacy intranet systems were built decades ago with very small storage budgets per record, often meant for a thumbnail-sized ID photo or a signature, not a full photo. A 20KB cap is common on these older systems even though most modern uploads allow far more.
What to expect at 20KB
- Small ID-style photos, roughly passport size, usually keep a recognizable, readable result.
- Detailed or high resolution photos need noticeable softening in both quality and pixel size to fit.
- Solid backgrounds and simple graphics compress the most easily, since JPEG and WEBP both handle flat areas efficiently.
20KB compared to other size targets
| Target | Typical use | What changes |
|---|---|---|
| 20KB | Old or very strict portals | Quality and often dimensions both reduced |
| 50KB | Signatures, small ID photos | Some quality reduction, dimensions rarely change |
| 100KB | General ID and application photos | Mostly a quality change only |
Compress to 20KB FAQ
Why is 20KB such a small limit?
Some older government and exam portals set very small upload caps, often meant for signature or thumbnail-sized photo uploads, from systems built decades ago.
How does this hit the target exactly?
It searches for the highest quality that fits under 20KB, then shrinks the pixel dimensions too if quality alone cannot get small enough.
Will the photo look blurry at 20KB?
At 20KB most photos need to shrink in both quality and size, so fine detail is softened. It still works for its purpose: a clear, recognizable ID-style photo.
Can I choose a different size limit?
Yes. TabbyKit also has tools for 50KB and 100KB, or use Compress image to set your own quality.
What kind of source photo works best for a 20KB result?
A smaller, simpler photo, already close to passport size with a plain background, keeps more detail at 20KB than a full resolution phone photo with a busy background.
Does the tool crop my photo to hit 20KB?
No. It never crops. It only reduces quality and, if needed, shrinks the whole photo proportionally.
Can I compress a batch of photos to 20KB at once?
Yes. Drop several photos and each is compressed on its own to fit under 20KB, downloadable together as a ZIP.
Does the output keep the format I uploaded?
Yes, unless you pick JPG or WEBP from the format dropdown. Both usually compress smaller than keeping an original PNG at such a tight target.
