Compress and resize passport photos (20–50 KB, 200x230 px) and signatures (10–20 KB, 140x60 px) for SSC CGL, CHSL, MTS, and GD online forms. 100% in-browser.
Supports JPG, PNG, WebP, HEIC/HEIF • Automatically compresses to 50 KB
Many online application systems enforce strict minimum byte thresholds to reject over-compressed photos. ExactKB injects benign JPEG COM comments to bring files safely above the minimum limit without modifying pixels.
Automated portal validators inspect the APP0 JFIF header. Standard smartphone photos default to 72 or 96 DPI, causing automated rejections. ExactKB writes standard 200/300 DPI headers directly into the stream.
All image compression, HEIC decoding, thresholding, and name/date stamp overlays run 100% locally in your browser’s volatile RAM. No image data is ever uploaded to any server.
