Stamp size photos (commonly 2 × 2.5 cm in India) appear on school, college, admission, and some office forms. They’re smaller than passport 3.5 × 4.5 cm, so using a passport file without resizing can fail dimension checks or leave the face looking wrong on printed labels.
Imgician pre-fills stamp size so you can resize at home on phone or desktop.
Steps
- Open Resize image to stamp size.
- Upload a clear face photo.
- Confirm 2 × 2.5 cm.
- Cast the spell and download.
- If the form has a KB cap, compress with 50KB or 20KB.
Stamp size vs passport / Aadhaar
| Size name | Typical cm | When it’s used |
|---|---|---|
| Stamp size | 2 × 2.5 cm | Many school/college/office forms |
| Passport / Aadhaar-style | 3.5 × 4.5 cm | Passport, Aadhaar, many exams |
| PAN-style | 3.5 × 2.5 cm | PAN applications |
If the form literally says “passport size,” use 3.5×4.5 cm — not stamp size.
Framing tips
Stamp photos are small. Start with a tight head-and-shoulders crop:
- Crop or crop free so the face fills most of the frame.
- Resize to stamp size.
- Compress only if needed.
A wide full-body photo shrunk to 2×2.5 cm will look like a tiny blob.
Print vs digital
- Digital forms: JPG + correct cm + KB limit.
- Physical forms: resize correctly, then print at the stated size; ask the print shop to verify centimeters on the ruler.

When the form says “stamp size” but means something else
In casual Indian usage, people sometimes say “stamp size” when they mean any small ID photo. If the printed form shows a box closer to passport proportions, measure the box or read the cm printed on the form.
- Box looks tall like a passport → try 3.5×4.5 cm
- Box looks short/wide like PAN → try 3.5×2.5 cm
- Form literally prints 2 × 2.5 cm → stay with stamp size
Digital upload checklist
- Correct 2 × 2.5 cm (or the stated size)
- JPG format (converter / HEIC to JPG)
- Under the KB limit if any
- Face large enough in the frame to stay readable after print or upload compression
FAQ
Can I reuse a passport photo for stamp size?
You can crop and resize it, but the aspect ratio differs — don’t just shrink a 3.5×4.5 file without checking the face framing.
Will Imgician print the photo?
No — it prepares the digital file. Take the download to a print shop if the form is physical.
Is processing private?
Yes. Resize runs in your browser; Imgician doesn’t upload your photo for this tool.
