How the Image Compressor to 100KB Works
Many online application portals, especially government recruitment systems in India (such as UPSC, SSC, IBPS, and state PSC exams), mandate passport photo uploads to be compressed to **exactly 100KB or less**. This browser tool runs an automated local canvas-rescaling iteration loop. It recursively adjusts quality values (from 0.99 down to 0.01) and image width/height dimensions inside your browser's offscreen memory, guaranteeing that the exported file meets size criteria without uploading your personal files to any third-party servers.
Common Government Exam Upload Constraints
When preparing application materials, sellers and students must satisfy strict digital requirements:
- Passport Photo: Typically sized between 20KB and 50KB.
- Signature Scan: Generally restricted to under 20KB.
- Supported Formats: Strictly JPG or JPEG. If you select standard PNGs, our converter compiles it directly to a compliant JPEG format.
Frequently Asked Questions
What images can I compress to 100KB?
You can upload any JPG, PNG, WEBP, or HEIC image. The tool will automatically compile it to a highly compatible JPEG format under 100KB.
Are my photos secure?
Yes. All file actions, conversions, and rendering runs client-side. We never store or inspect your documents, satisfying strict privacy policies.
Why does the resolution change?
If the source image contains high pixel dimensions, quality compression alone cannot meet the 100KB target size. The engine scales the width and height down proportionally to compress the size successfully.
