Which portals require 20 KB photos?
The 20 KB photo size limit is common on government exam and registration portals across India and Indonesia. Below are examples of systems that frequently enforce this or a similar small-KB limit:
- SSC (Staff Selection Commission) — India: Some SSC exam cycles specify a 20–50 KB range for the candidate photo upload.
- State PSC portals — India: Rajasthan RPSC, UP UPPSC, Bihar BPSC, and similar state PSC portals frequently set 20–40 KB photo limits.
- Railway Recruitment Board (RRB) — India: RRB NTPC and Group D applications have required photos in the 20–40 KB range.
- Municipal Corporation recruitment portals — India: Local government vacancy portals often enforce tighter file size limits than national portals.
- CPNS / ASN registration — Indonesia: Seleksi CASN and similar Indonesian civil service portals specify small file sizes (15–50 KB) for photo and signature uploads.
Always confirm the exact limit on your specific portal's application guide before uploading. Requirements change between application cycles.
Tips for compressing to 20 KB with the best quality
- Use JPEG, not PNG. PNG is lossless and produces much larger files for photos. Convert your image to JPEG first — most portals only accept JPG for photo uploads anyway.
- Reduce pixel dimensions first. If your photo is 1000 px wide or larger, resize it to around 200–300 px wide before targeting 20 KB. A smaller source image compresses to 20 KB with much higher visual quality than a large image forced down to the same size.
- Use a plain white or light background. Solid backgrounds compress more efficiently than complex backgrounds. A passport-style photo against white will reach 20 KB at higher quality than a photo with a busy background.
- Check the portal's pixel dimension requirements too. Many portals specify both a KB limit AND a pixel dimension range (e.g., 200x230 px). Match both requirements simultaneously.
FAQ
Which portals require photos to be exactly 20 KB?
Many Indian government portals including SSC, state PSC boards, and railway recruitment portals specify 20 KB limits. Indonesian CPNS and civil service registration portals also often require small file sizes in the 15–25 KB range. Check your specific portal's instructions before uploading.
Will a 20 KB photo look acceptable on a government form?
Yes, when prepared correctly. Reduce the pixel dimensions to around 200–250 px wide first, then compress to 20 KB as JPEG. At that size, a passport-style photo retains enough clarity for identity verification. Compressing a very large image to 20 KB without resizing first will look blurry.
Should I use JPEG or PNG when compressing to 20 KB?
Always use JPEG. PNG cannot practically reach 20 KB for photos without extreme quality degradation. Convert to JPEG first, then compress. Most government portals only accept JPEG anyway.
What pixel dimensions should my photo be before compressing to 20 KB?
Around 200–250 px wide. A passport-style photo at 200x250 px compressed as JPEG will reach 20 KB at good visual quality. If your photo is larger, resize it first, then compress to 20 KB.
Is 20 KB the same as 20,000 bytes?
In practice, most portals mean 20,000 bytes (decimal KB). UploadReady targets this value. This is the safer limit and will pass validators that use either binary or decimal definitions of "KB".
