Which Forms Need 100KB?
- RRB Group D — photo up to 100KB.
- JEE Main — signature up to 100KB.
Need an exact pixel size too? Use the Exam Photo & Signature Resizer, which sets both dimensions and KB range together from each exam's official spec.
Frequently Asked Questions
What kind of upload limits sit around 100KB?
100KB is a common ceiling for ID document scans (Aadhaar, PAN, marksheets) and profile photos on job portals and government e-services — larger than the tight 20-50KB passport-photo range, but still small enough that a site keeps thousands of uploads light.
Is 100KB enough to keep a scanned document readable?
Yes, for a typical ID card or certificate scan — this tool searches for the highest JPEG quality that still fits under 100KB, which at this size comfortably preserves printed text and photo detail, unlike the much more aggressive compression a 20-50KB target needs.
My scanned PDF page is too big — can I use this?
This tool compresses image files (JPG, PNG, WebP), not PDFs. If your document is a PDF, export or screenshot the page as an image first, or check whether the portal accepts a direct PDF upload instead.
Does it also resize the image's pixel dimensions?
No — only the file size changes here, dimensions stay as uploaded. If a form also specifies an exact width and height (most passport-style photo specs do), use the Exam Photo & Signature Resizer instead, which sets both together.
