About Us
We build secure, privacy-first tools to help you prepare documents for immigration, passport, and government portals worldwide.
Our Mission
100kb.in was built to solve a specific, frustrating problem: resizing and formatting sensitive personal documents (like passports, IDs, and signatures) to meet strict government portal requirements, without compromising privacy. We believe that you shouldn't have to upload your most sensitive identity documents to a remote server just to change a file size or format.
Why Trust Us? (E-E-A-T)
Our tools utilize WebAssembly (Wasm) and native browser APIs to process your files entirely on your device. Your photos and PDFs never leave your browser, ensuring absolute privacy and zero risk of data interception.
Our guidelines are researched directly from official government portals (USCIS, UKVI, IRCC, etc.). We constantly monitor for updates to ensure our tools crop, resize, and compress to the exact DPI and byte limits required.
Because files are never uploaded, there is no database to hack and no files to delete. Once you close the tab, all processed data is instantly wiped from your browser's memory.
We leverage open-source, battle-tested libraries (like FFmpeg.wasm and PDF-lib) to power our tools. This transparent approach ensures security through community-audited codebases.
