Resize photo & signature for Aadhaar (UIDAI) (20–500 KB) — Free & Private
Aadhaar — UIDAI document upload and self-service portal. Conducted by Unique Identification Authority of India.
Photograph
Aadhaar processes don't typically require an online photo upload — the photograph is captured biometrically at an authorised enrolment centre. However, UIDAI's Self-Service Update Portal (SSUP) and other Aadhaar workflows do require document scans, and a recent passport-style photograph is sometimes needed at the enrolment centre. This page covers both.

Frequently asked questions
Does Aadhaar require a photo upload online?
Generally no — your Aadhaar photograph is captured biometrically at an authorised enrolment / update centre. Online uploads are used for proof of identity / address documents and, rarely, for facial photographs in specific UIDAI workflows.
What is the document upload limit on UIDAI SSUP?
Documents uploaded on the Self-Service Update Portal must be JPEG / JPG / PNG or PDF, with a maximum file size of 2 MB per document.
What size passport photo do I need at an Aadhaar enrolment centre?
Aadhaar enrolment uses a live photograph captured at the centre. If a printed passport-size photo is asked for (rare), use the Indian passport-photo standard: 3.5 cm × 4.5 cm on a white background.
How do I shrink my Aadhaar document scan to under 2 MB?
Use the Aadhaar preset on this page. PhotoSahi will compress your JPEG / PNG to land safely under 2 MB without distorting the page.
