Published sizes disagreed. We checked the notification.Resolved against the GDS Online Engagement Notification, Schedule-II, July 2026, paragraph 5 (pages 23–24). Photograph: JPG, 30–100 KB, recommended 320 × 400 px, aspect ratio 4:5 (width:height), DPI 72–150. Signature: JPG, 20–100 KB, recommended 300 × 120 px, aspect ratio 5:2, DPI 72–150. The stored pixels and KB bands already matched. This file is written at 150 DPI, the top of that range, because 200 DPI is outside it. The portal user manual dated 1 February 2026 (page 20) still says the signature maximum is 50 KB and calls the photograph aspect “5:4 (portrait)”. The July notification is the later document. A signature between 50 and 100 KB matches the notification and not that manual.

How it works
Exam-ready photo and signature in three steps. No editing skills, no software, no upload.
1
Pick your exam
Choose from 129 presets. 35 have been checked against the official notification; every other page says it has not. Pixels, KB band and DPI load with the preset. Not listed? Type your own numbers.
2
Upload and adjust
Drag to position your face, pinch or scroll to zoom. Signatures get one-slider background clean-up. Add your name and the date if the board wants them printed on the photo.
3
Check and download
You get exact dimensions, a file inside the KB band, correct DPI — and a pre-flight report on blur, background and face position before you upload anything.

Questions
What photo size is required for India Post GDS?
The GDS Schedule-II July 2026 notification, pages 23–24, states the photograph as JPG, 30–100 KB, recommended 320 × 400 px, DPI 72–150, and the signature as JPG, 20–100 KB, recommended 300 × 120 px, DPI 72–150. This file is written at 150 DPI. The February 2026 portal manual still says a 50 KB signature ceiling.
My file is smaller than 30 KB. Will it be rejected?
Yes. 30 KB is a floor, not a suggestion, and portals reject files under it exactly as they reject oversized ones. This tool lifts an undersized file over the floor by appending blank JPEG comment data, which decoders ignore. The picture itself is untouched — some tools inject random noise into the image instead, which visibly degrades it.
Are my photos uploaded anywhere?
No. The resizing runs inside your browser using the standard canvas API. Nothing is sent to a server, there is no account, and the page keeps working offline once loaded.
Can I set the DPI?
Yes, and it defaults to 150 DPI here. Browsers write 96 DPI into canvas JPEGs, and some portals read that field and reject the file even when the pixel dimensions are correct. The value is written into the JFIF header of the file you download.
Why do other sites list a different size for India Post GDS?
Resolved against the GDS Online Engagement Notification, Schedule-II, July 2026, paragraph 5 (pages 23–24). Photograph: JPG, 30–100 KB, recommended 320 × 400 px, aspect ratio 4:5 (width:height), DPI 72–150. Signature: JPG, 20–100 KB, recommended 300 × 120 px, aspect ratio 5:2, DPI 72–150. The stored pixels and KB bands already matched. This file is written at 150 DPI, the top of that range, because 200 DPI is outside it. The portal user manual dated 1 February 2026 (page 20) still says the signature maximum is 50 KB and calls the photograph aspect “5:4 (portrait)”. The July notification is the later document. A signature between 50 and 100 KB matches the notification and not that manual. We would rather show you the disagreement than pick one and sound certain.
