100KB Extension v1.1.1: Compress & resize files in 0ms directly in Google Chrome
Convert JPG, JPEG, and PNG images into PDF files. Automatically scale and compress pages to fit under your desired limit.
Online application forms frequently demand supporting documents—such as passport photos, educational marksheets, degree certificates, and identity cards—to be uploaded strictly in PDF format under 100KB or 200KB, even if you took the photo with a smartphone camera as a JPG or PNG.
Converting raw images into standardized PDFs involves more than changing the file extension. Renaming image.jpg to image.pdf creates an invalid file that government portal scrapers reject immediately. Our client-side JPG to PDF converter wraps your image pixels inside a compliant PDF/A container object tree, applies bi-cubic dimension scaling, and deflates image streams so the output PDF is instantly accepted by official validation systems.

| PDF / A-1b (Scanned Certificates) | FlateDecode + Bi-Cubic Resampling (150 DPI) | 100KB – 300KB | Retained as Vector | 100% (UPSC, NTA, SSC, IBPS) |
| Standard PDF / 1.7 (Multi-Page) | Stream Dictionary LZ77 Deflate | 200KB – 1MB | Full Font Subsetting | 100% (USCIS, UKVI, IRCC) |
| High-Res Print PDF | Uncompressed Native Stream | 2MB – 10MB | Embedded TrueType | Requires Compression for Portal Caps |
