Frequently Asked Questions (Document & Certificate Resizer)
What is the standard file size for uploading marksheets and certificates?
Most central and state government exam portals (SSC CGL/CHSL, UPSC, State PSCs) mandate that uploaded educational marksheets, caste certificates, and domicile proofs fall between 100 KB and 300 KB (or 50 KB and 200 KB) in JPG, JPEG, or PDF format.
Will compressing my 10th marksheet make roll numbers and seal stamps blurry?
No. The SignResize Document Resizer utilizes high-frequency text-edge sharpening algorithms that maintain high micro-contrast around numbers, signatures, and board stamps while lowering background photo noise.
Can I resize my Caste Certificate (SC/ST/OBC-NCL/EWS) or Domicile proof here?
Yes. Simply select the 'Caste Certificate' or 'Domicile Certificate' preset. The tool formats the image into a standard A4 portrait scan ratio with exact 100 KB โ 300 KB bounds.
Is it safe to compress Aadhaar cards and sensitive certificates here?
Yes, 100%. SignResize runs completely in your device's browser memory via client-side HTML5 canvas. No files or documents are ever uploaded to external servers, providing maximum privacy for your documents.
