How to Compress a Photo and Signature for Exam Forms
Updated November 7, 2026
Exam forms usually set a size range in KB, a format and sometimes exact pixels. The safest route is to read the current notice, crop tightly, resize if pixels are given, then compress to just under the maximum. Some exams, including recent SSC ones, no longer take a saved photo at all, so check that first.
Compress a photo to 50 KBWhat two big exam bodies ask for
These rules come from official SSC and IBPS documents we checked in November 2026. Every exam has its own notice, and rules can change between cycles, so treat this as a guide and follow the notice for your exam.
| Exam body | Photo | Signature |
|---|---|---|
| SSC (CGL 2026 notice) | Captured live in the application, not uploaded from a saved file | JPG, 10 to 20 KB, about 6 cm × 2 cm |
| IBPS recruitment forms | 20 to 50 KB, 200 × 230 pixels preferred | 10 to 20 KB |
If your exam captures a live photo
The SSC CGL 2026 notice says candidates must not photograph an existing photo, and that applications doing so can be rejected. No compression tool applies here, because you take the picture through the application itself.
Face the camera in good, even light. The notice says not to wear a cap, mask or glasses. Keep your whole face inside the marked area, and don't sit with a bright window behind you, since that leaves your face dark.
You still upload a signature, so the rest of this guide applies to that.
How to get a photo inside the limit
Work in this order, because each step makes the next one easier and keeps the most quality.
- 1Read the notice and write down three things: the format, the KB range, and any pixel size.
- 2Crop to your head and shoulders. A blank wall still takes up file size.
- 3If pixels are listed, resize to exactly those numbers.
- 4Compress to a little under the maximum, such as 45 KB for a 50 KB limit.
- 5Zoom in on the result. Your face should look clear, with no blocky patches.
How to scan or photograph a signature
Sign with a black pen on plain white paper. Photograph it in daylight, holding the phone straight above the page so the signature isn't slanted. Avoid your own shadow falling across it.
Crop right up to the ink. Signatures are mostly white space, so a tight crop does much of the work. SSC says blurred or miniature signatures are rejected, so the signature should fill the image, and the crop needs to be sharp.
IBPS guidance says signatures in capital letters won't be accepted, so sign the way you normally do.
Why a form rejects your file
Most rejections come down to one of these.
| What went wrong | How to fix it |
|---|---|
| File is under the minimum | Compress less. A range like 20 to 50 KB rejects a 15 KB file too. |
| File is over the maximum | Crop tighter first, then compress again. |
| Wrong format | Save as JPG. iPhone HEIC files need converting. |
| Pixels don't match | Resize to the exact numbers before compressing. |
| Photo looks blurred | Start again from the original, not an already compressed copy. |
Mistakes that cost people time
Don't compress a screenshot of a photo. It's already lost detail, so it gets worse quickly. Keep the original, and always go back to it if you need another try. Our guide to photo size limits explains why.
Don't leave it until the last day. Application sites get busy near a deadline, and a rejected image is much harder to fix in a hurry. After you upload, check the preview on the form, because what you see there is usually what the exam body sees.
