Who needs a 20 KB image?
A 20 KB cap almost always means an Indian government or examination portal — SSC, UPSC, state recruitment boards, university admission systems. These sites were built when bandwidth was expensive and the limits have never been raised. They typically want a passport-style photo or a signature scan, and they reject the upload outright rather than compressing it for you.
What to expect at 20 KB
For a passport-style headshot this is comfortable — faces compress well and 20 KB is enough to stay clearly recognisable. For a signature scan it is more than enough. A full landscape photograph at 20 KB will look rough, but that is not what these forms are asking for.
A real example
A typical passport-photo crop of 600x800 pixels lands at 20 KB with quality to spare. The same 20 KB spent on a full 4000x3000 holiday photo would look badly degraded — which is why cropping first matters so much at this tier.
Which format to use for 20 KB
Use JPG. Almost every portal that enforces a 20 KB cap also demands JPG specifically, and JPG is the only format that reaches this size with a face still looking natural.
Getting the best result at 20 KB
- Check the portal's pixel dimensions too — most 20 KB forms also specify width and height
- Resize first, then compress; that order always gives a cleaner result
- Signatures and documents reach 20 KB comfortably, so save your effort for the photo

FAQ
The form also specifies pixel dimensions. What do I do?
Resize to those dimensions first with our resize tool, then come back and compress to 20 KB. Doing it in that order gives you the best quality, because the compressor works on fewer pixels.
It says minimum 10 KB and maximum 20 KB. Will this work?
Yes. The tool targets just under your limit rather than compressing as hard as possible, so the result normally lands inside that band. Check the resulting size shown before you download.
Frequently Asked Questions
How do I compress an image to exactly 100 KB or 50 KB?
Upload your image, pick a target (20 KB, 50 KB, 100 KB, 200 KB, 500 KB) or type a custom size in KB, then click Compress. The tool automatically tests quality levels — and reduces the dimensions if needed — to land at or just under your target size.
Are my images uploaded to a server?
No. Everything happens in your browser. Your image never leaves your device — there is no upload and nothing is stored. This makes it safe for IDs, documents and personal photos.
Why do I need an image of an exact size?
Many websites and government / exam / job application forms require photos under a specific size, such as 50 KB or 100 KB. This tool gets you under that limit without manual trial and error.
What if my target size is too small for the image?
If a size is impossible without destroying the image, the tool produces the smallest acceptable version it can and tells you it could not reach the exact target. Try a slightly larger target or a smaller starting image.
Which output format should I choose?
JPG gives the smallest files and is accepted almost everywhere, so it is the default. WEBP can be a little smaller at the same quality but is not accepted by every form. If a form asks for JPG/JPEG, choose JPG.
