The Staff Selection Commission conducts major national recruitment examinations including SSC CGL, CHSL, MTS, CPO, and GD Constable via its official portal at ssc.gov.in (Last Verified: October 2026 for 2026–2027 Recruitment Cycles). During peak application periods, thousands of candidates face rejection because their scanned documents exceed strict server thresholds.
The official SSC application system automatically checks file byte boundaries upon selection. Certificates exceeding 200KB or below 100KB trigger an immediate 'File size out of range' rejection dialog. PDFBolt allows you to set an exact target such as 150 KB, placing your file squarely in the approved range without pixelating text or stamps.
School marksheets, university degree certificates, and caste validity forms scanned at standard cyber cafes are often saved at 300 or 600 DPI in 24-bit RGB color. Even a single-page document can weigh 2MB to 5MB due to paper texture noise and yellowing backgrounds.
Enabling PDFBolt's 'Convert to Black & White (Grayscale)' option eliminates unnecessary color chroma channels while preserving sharp 300 DPI text edges and official signatures. This single toggle drops file size by 60% to 80%, effortlessly meeting SSC's 100KB–200KB limit.
A common risk with aggressive online compression is fuzzy text. If the SSC document verification committee cannot clearly read your secondary board roll number, school code, or the issuing authority's stamp, your candidature can be put on hold.
PDFBolt uses intelligent vector preservation: fonts and text characters remain vector-sharp, while only the background raster scanner artifacts are optimized. Your roll number, passing year, and signatures stay crisp at any zoom level.
This error triggers when your uploaded file is larger than 200KB or smaller than 100KB. Use PDFBolt's 'Exact Target Size' mode and set 150 KB to ensure your file lands safely in the middle of the acceptable window.
Per official ssc.gov.in guidelines: Educational and Category certificates must be in PDF format between 100KB and 200KB. Candidate photographs must be 20KB to 50KB (JPEG), and signatures must be 10KB to 20KB (JPEG).
Select 'Exact Target Size' and enter 180 KB. If the file is a color scan of an old certificate, turn on the 'Convert to Black & White (Grayscale)' switch to strip background paper noise and guarantee crisp text.
