Frequently Asked Questions (FAQ)
Common queries about resizing images, fixing portal upload errors, and converting documents.
How to fix "Photo size too large" or "File must be between 20 KB and 50 KB" error?
Government portal upload validators reject images that exceed 50 KB or fall below 20 KB. In our resizer tool, simply select the SSC Photo (20-50 KB) preset. Our engine automatically adjusts JPG quality parameters and recalculates file bytes before download to guarantee the output is strictly within the allowed range.
Can I resize photo and signature on mobile without downloading any app?
Yes! This web tool runs directly in Google Chrome, Safari, or any mobile browser using client-side HTML5 canvas. Your photos are processed in your phone's memory without being sent to external servers, protecting your privacy.
What is the correct left thumb impression size for IBPS and Railway RRB?
For IBPS Bank PO/Clerk and RRB Railway exams, the applicant's left thumb impression must be scanned on white paper with blue or black ink. Dimensions should be 3 cm × 3 cm (240 × 240 pixels at 200 DPI), and file size must be strictly between 10 KB and 20 KB in JPG format.
Why do cyber cafe and Xerox shop operators choose DocuMate® Windows software?
