Exam Photo & Signature Resizer
Resize your photo or signature to the exact KB size your form demands — 20KB, 50KB or any custom target — with presets for SSC, UPSC, IBPS, SBI, RRB, NEET and JEE. Also works for job portals, admissions and ID updates via the custom KB option.
🔒 Nothing is uploaded. All processing happens in your browser — your image never reaches our server.
How to resize a photo for exam forms
Most portals reject photos for one of three reasons: file size over the KB limit, wrong pixel dimensions, or non-JPEG format. The presets here fix all three together.
- Upload your photo or signature. Any JPG, PNG or iPhone HEIC image — HEIC converts to JPEG automatically, since portals don't accept it.
- Select your exam or a KB target. One tap applies the official KB range, dimensions and format — or set any custom target for job portals, admissions and other forms.
- Download the exam-ready file. The meter shows the final size, so you know it will pass before leaving this page.

Frequently asked questions
How do I resize a photo to 20KB without losing quality?
Choose the 20KB target — the tool balances JPEG quality and dimensions in an iterative loop, stopping the moment the file fits under the limit instead of blindly over-compressing, which is what makes photos blurry.
Is my photo uploaded to a server?
No. The entire resizer runs in your browser using Canvas. Your photo and signature never leave your phone or computer — there is no copy on any server to leak or misuse.
What photo size is required for SSC?
SSC requires a recent JPEG photo of 20–50 KB and a signature of 10–20 KB. The SSC preset applies these together — and always confirm against the current-year notification.
Can I resize an iPhone HEIC photo?
Yes — HEIC images are converted to JPEG automatically before resizing, since government portals only accept JPEG.
