Published sizes disagreed. We checked the notification.Resolved against the same Photos and Signature instruction. The CDS (II) 2026 notice requires an uploaded photograph, a live photograph and a triple signature, and it states no file size of its own. It points at the same instructions. Photograph JPG 20–200 KB, no pixel size. Signature JPG 20–100 KB, 350–500 pixels. There was no CDS preset before this; NDA and CAPF already had their own pages, and CDS uses this portal rule rather than CAPF’s appendix.

- Photograph JPG, file name photo, 20–200 KB, plain white background, face covering at least three quarters of the frame. The instruction states no pixel size. 400 × 400 is a crop the editor keeps, not a figure in the instruction. Do not sign the photograph. The portal also captures a live photograph and matches it to this one.
- Signature Three signatures, one below the other, in black ink on plain white paper. JPG, file name signature, 20–100 KB, image dimensions 350–500 pixels. The instruction does not say which side. 400 × 400 sits inside that range.

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 UPSC CDS?
The UPSC portal instruction for Photos and Signature states a JPG photograph of 20–200 KB and no pixel size. The signature is three signatures in one JPG, 20–100 KB, with image dimensions of 350–500 pixels. It does not say which side. 400 × 400 sits inside that range. The portal also captures a live photograph. This is the instruction the examination notice points to. It is not the CAPF appendix, and it is not the retired OTR FAQ that still says 20–300 KB.
My file is smaller than 20 KB. Will it be rejected?
Yes. 20 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 200 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 UPSC CDS?
Resolved against the same Photos and Signature instruction. The CDS (II) 2026 notice requires an uploaded photograph, a live photograph and a triple signature, and it states no file size of its own. It points at the same instructions. Photograph JPG 20–200 KB, no pixel size. Signature JPG 20–100 KB, 350–500 pixels. There was no CDS preset before this; NDA and CAPF already had their own pages, and CDS uses this portal rule rather than CAPF’s appendix. We would rather show you the disagreement than pick one and sound certain.
