Photo & signature requirements for exams
Indian government application portals are strict about photo and signature size. If your upload is even a few kilobytes too large, the form rejects it and you waste time re-cropping in paint or other editors. The most common requirements are a photo between 20kb and 300kb and a signature between 2kb and 20kb, with specific pixel or centimetre dimensions for each exam.
The good news: you don't need paid software. A free online photo & signature resizer sets both the KB target and the width and height (in cm or px) at the same time, so the file is always accepted on the first attempt.
SSC photo and signature resizer
The SSC (Staff Selection Commission) portal typically requires a photo of 20kb to 50kb and a signature of 10kb to 20kb, both in JPG format. If you're preparing an SSC photo and signature resizer online kb and cm setup, set your target to 20kb or 30kb and pick the pixel size mentioned in your notification — usually around 200x230 px for the photo.
Use the quick presets on the Photo & Signature Resizer page: the Photo 200 x 230 px preset handles the photograph and the Signature 6cm x 2cm preset handles the signature.
UPSC photo resize to 20kb to 300kb
UPSC and many banking portals accept a slightly wider range. A UPSC photo resize to 20kb to 300kb tool is all you need: choose any target inside that range — say 50kb or 100kb — and the tool compresses automatically. If your notification asks for a specific dimension like resize jpeg to exact 20kb dimension 200x230 px, type 200 and 230 into the width and height boxes and pick the 20 KB pill.
Railway NTPC photo and sign compressor
Railway Recruitment Board (RRB) forms, including NTPC, Group D and ALP, require a Railway NTPC photo and sign compressor online free. The photo is usually 20kb to 50kb and the signature 10kb to 20kb. Upload both files one at a time, set 20kb for the signature and 50kb for the photo, and download each resized JPG. Because everything runs in your browser, there is no upload risk for your personal documents.
IBPS signature resize in cm and kb
IBPS (Institute of Banking Personnel Selection) asks for a signature with exact dimensions in centimetres — commonly 6cm x 2cm under 20kb. For an IBPS signature resize in cm and kb, select the Signature 6cm x 2cm preset, confirm the 20 KB target is active, and download. The tool converts centimetres to pixels automatically using standard print resolution, so the signature keeps the right aspect ratio.
Tip: if your signature file is already tiny (a few KB), you can also convert it to a PDF and merge it with your documents using the JPG to PDF tool, then sign the final PDF with Sign PDF.
How to resize in 3 steps
- Upload. Drop your JPG, JPEG or PNG photo or signature into the Photo & Signature Resizer box. Everything stays on your device.
- Choose size. Tap the KB target required by your form (20kb, 50kb, 100kb, 200kb, 300kb or a custom value) and, if needed, enter the exact width and height in cm or px, or use a preset.
- Download. Click Compress & Download. Your image is saved under the target KB, ready to upload.
If you only need to shrink a large image to a specific KB and don't care about dimensions, the Image Compressor is even simpler — pick the target and download.
Can I make a passport size photo with a white background?
Yes. For an exam that asks for a passport-size photo, crop your image to 3.5cm x 4.5cm using the Passport 3.5 x 4.5 cm preset, then compress to the required KB. To make passport size photo background white online free, choose a photo taken against a plain light wall, increase contrast slightly, and the JPEG compression will keep the background looking clean and white.
Frequently asked questions
How to resize signature to 140x60 pixels under 20kb?⌄
Select the Signature 140 x 60 px preset on the resizer, keep the 20 KB target selected, then click Compress & Download. The output will be 140 x 60 pixels and under 20kb.
What if my photo is already under the KB limit?⌄
Then you only need to check the dimensions. Set the width and height required by the portal, leave a target KB that is higher than your current file size, and download — the tool only compresses enough to fit.
Are my photos uploaded to a server?⌄
No. Both the resizer and the compressor run entirely in your browser. Your photos and signatures never leave your device.
Which format should I use for exam uploads?⌄
Most Indian portals accept JPG or JPEG. Upload a JPG or PNG, and the tools output a JPG under the target size, which works for the vast majority of applications.
