Make a 3×4 cm photo (354 × 472 px)
A 3×4 cm photo is a standard requirement for applications, ID cards, and government forms, especially in Indonesia. The correct digital size depends on the resolution: at 300 DPI it is 354×472 pixels, at 150 DPI it is 177×236 pixels. This preset uses 300 DPI, crops to a clean 3:4 portrait ratio, and compresses to 200 KB because that is a frequent portal limit. The crop is centred, so choose a source photo with the face near the middle and some space above the head. If a portal specifies a different file size or dimensions, change the target before processing. Rules differ between agencies and selection years, so the official instructions always win.

How do I resize a photo to 3×4 cm?
Upload a portrait, and Toolabs crops it to the 3:4 ratio at 354×472 pixels, the standard 3×4 cm size at 300 DPI. It then compresses the JPG to 200 KB by default. Choose a source with the face centred, adjust the target size if your portal uses different rules, then download.
How to use it
- Upload a recent portrait with the face clearly visible and a plain background.
- The crop is set to 3:4 and 354×472 px. Adjust the crop position only by choosing a better source photo.

- Process the photo and check the preview, dimensions, and file size.
- Download the JPG and submit it where the 3×4 cm photo is required.

At a glance
| Print size | Pixels at 300 DPI | Typical use |
|---|---|---|
| 2×3 cm | 236×354 | Small application forms, student cards |
| 3×4 cm | 354×472 | CPNS, job applications, general forms |
| 4×6 cm | 472×709 | Larger application photos, visas |
| 6×9 cm | 709×1063 | Some passport and immigration requirements |
Always confirm the current size, background colour, and file limit in the official portal instructions.
Use a plain background and soft, even lighting. Compression preserves a clean portrait better than a busy background with fine patterns.
Frequently asked questions
What is the exact pixel size of a 3×4 cm photo?
At 300 DPI it is 354×472 pixels. At 150 DPI it is 177×236 pixels. For online portals, 354×472 px is the safer choice because it keeps enough detail for both screen and print.
Is 354×472 px the same as 3×4 cm?
It becomes 3×4 cm when printed at 300 DPI. The file itself stores pixels; DPI is metadata that tells a printer how densely to place them. Some portals ignore DPI and only check pixels and file size.
Why is the target set to 200 KB?
Many Indonesian government and recruitment portals use a limit around 200 KB. Requirements vary, so change the target if your official instructions say 100 KB, 500 KB, or another number.
What background should a 3×4 photo have?
Follow the specific portal. Red, blue, and white backgrounds are all used in Indonesia for different purposes. This tool does not replace the background; it only crops and compresses the photo you provide.
Can I use a phone photo?
Yes, if the face is well lit and the background is not distracting. Phone cameras produce excellent portraits. Avoid heavy beauty filters and wide-angle distortion, and make sure the head and shoulders fit the 3:4 crop.
Does the tool print the photo?
No. It produces a digital JPG that you can print at a photo shop or upload to a portal. For a print sheet with multiple copies, use your print shop’s layout service.
