100KB Extension v1.1.1: Compress & resize files in 0ms directly in Google Chrome
Reduce image file size in KB or MB online. Compress JPG, PNG, and WebP files securely without changing dimensions. Formatted for SSC Photo.
To ensure your photo is accepted by the India official platform, it must meet the following strict criteria:
Disclaimer: These requirements are verified based on official guidelines. However, platform rules and guidelines can change. Always consult the official SSC Photo portal before final submission.
Submitting an application for India's Staff Selection Commission demands absolute adherence to their specific image formatting guidelines. A photograph that is blurred, wearing a cap, or exceeding the rigid 50KB limit will result in immediate disqualification of your candidature. Our dedicated editor swiftly resizes and compresses your headshot, guaranteeing it meets every single SSC parameter flawlessly. Government job portals, university application systems, and e-commerce platforms impose strict file size limits on uploaded photos—most commonly requiring candidate photographs to be under 20KB, 50KB, or 100KB. Attempting to compress high-resolution smartphone photos (which are usually 3MB to 8MB) using basic tools often causes heavy pixelation, making faces unrecognizable.
100kb.in uses an iterative client-side binary search quantization engine. It converts RGB pixels to YCbCr color space, applies 4:2:0 chroma subsampling, and executes a 7-iteration binary search loop inside browser memory. In under 15 milliseconds, it selects the maximum quality setting that yields a byte size strictly under your requested target limit (e.g. 50KB or 20KB) while maintaining 300 DPI facial clarity.
| Format | Quantization Engine | Color Space & Subsampling | Target Size Ceiling | Portal Acceptance |
|---|---|---|---|---|
| JPEG / JPG | Lossy 8x8 DCT Frequency Quantization | YCbCr (4:2:0 Subsampling) | 20KB – 500KB | 100% (Universal Exam & Visa Portals) |
| PNG | Lossless Deflate / LZ77 Filtering | RGB + 8-bit Alpha Channel | 100KB – 2MB | E-commerce, Logos & Digital Design |
| WEBP | VP8 Intra-frame Prediction | YCbCr 4:2:0 / Lossless | 15KB – 300KB | Modern Web Apps & Mobile Display |
Follow these simple steps to ensure your file meets all requirements for SSC Photo.
Select or drag your JPG, PNG, or WEBP photo into the compression dropzone. Upload a clearly visible portrait taken recently, ensuring you are not wearing spectacles or headgear (except for religious purposes).
Choose a preset size limit (e.g. 20KB, 50KB, 100KB) or type a custom byte ceiling. Crop the picture to exactly 3.5 cm in width and 4.5 cm in height, keeping the file size contained between 20KB and 50KB.
The browser-based solver optimizes JPEG quantization matrices in milliseconds. Retrieve the finalized JPEG, perfectly suited for the SSC registration portal without triggering any dimension errors.
