Resize Image to 20KB
Compress photo or signature to under 20KB for SSC, UPSC and exam uploads. Browser-only.
SSC, UPSC, and exam photo size requirements
Nearly every Indian government competitive exam — SSC CGL, SSC CHSL, UPSC Civil Services, RRB NTPC, SBI PO, IBPS, NEET, and others — requires candidates to upload a passport-size photo and a signature image within strict file size limits. The photo is typically capped at 20 KB and the signature at 10 KB. Uploading a file that exceeds these limits results in an error, and many candidates discover this only on the last day before the deadline.
How this tool hits the target
This tool uses a binary-search algorithm over JPEG quality settings. It starts at mid-range quality, checks the resulting file size, then adjusts up or down until it finds the highest quality that fits within your target KB. The process happens entirely in your browser — no upload, no account. You can see the resulting size before downloading.
Photo vs signature presets
Use the SSC/UPSC Photo (20 KB) preset for your passport-size photograph, which sets max width to 200 px matching the standard 3.5×4.5 cm scan. Use theSignature (10 KB) preset for your handwritten signature photo, which allows a wider max width (280 px) since signatures are landscape-oriented. If your portal has different requirements, select Custom and enter the exact target KB and max dimension.
After downloading, always verify the file size in your system's file properties before uploading it to the exam portal. The tool displays the achieved file size prominently for quick verification.
Frequently Asked Questions
Why do SSC and UPSC exams require photos under 20 KB?
Government exam portals impose strict size limits to reduce server storage and ensure consistent uploads. Typically, the photo must be 20 KB or less and the signature 10 KB or less.Will my photo quality be acceptable for the exam portal?
Yes. The tool compresses to just under the KB limit while keeping the maximum possible quality. Exam portals check file size, not visual quality rating.Does this tool upload my photo anywhere?
No. Compression is done entirely in your browser. Your photo, signature, or any document never leaves your device.What dimensions should the SSC photo be?
SSC typically asks for 3.5 cm × 4.5 cm (200×230 px at 72 dpi) at under 20 KB. Use the SSC/UPSC Photo preset which sets max width to 200px automatically.What if the tool cannot get the file below 20KB?
This can happen if the source image is very large and complex. Try scanning or photographing with lower resolution first, or cropping to remove background. The tool will report the achieved size.Can I use this for NEET, RRB, bank exams too?
Yes. Most Indian government exam portals use the same 10–20 KB limits. The Custom preset lets you enter any target KB and dimension that the portal specifies.
