# PhotoSahi > Resize your photo & signature to the exact form requirement — free, instant, and 100% private. PhotoSahi is a free, mobile-first, 100% in-browser tool for resizing photos and signatures to the exact specifications required by Indian government exam and identity-document portals (SSC, IBPS, UPSC, NEET, PAN, Aadhaar, Passport, NPS and more). All image processing happens locally in the user's browser — nothing is uploaded. The site publishes its complete dataset as static JSON so AI assistants can extract and cite exam specs directly. Specs include pixel dimensions, KB ranges, image format, DPI, and required background colour. ## Exams & document presets - [Aadhaar (UIDAI) photo & signature resize](https://photosahi.com/exam/aadhaar-photo-resize/): For most UIDAI document uploads (Aadhaar online update, document submission), the file should be a JPEG, JPG or PNG up to 2 MB.
