Tips for a clean 30 KB file

• •With 30 KB you can keep a slightly larger pixel size — useful if the form prints your photo on an admit card.
• •Avoid screenshots of photos; re-compressing an already compressed image adds blockiness.
• •If your form sets a minimum (for example 20 KB), check the downloaded file size is above it before uploading.
• •Need a different shape than 350×450 px? Tick "Keep original dimensions" — the photo is compressed to 30 KB without cropping.

Frequently asked questions

How do I resize a photo to 30 KB without losing clarity?

Upload it above — the tool outputs a 350×450 px JPEG and automatically tunes quality until the file is under 30 KB. At these dimensions the compression is visually clean for form photos.

What are the pixel and centimetre dimensions of a 30 KB photo?

KB is file size, not pixel size, so there is no fixed conversion. This page outputs 350×450 px (3.5×4.5 cm at standard print resolution), the common passport-photo shape. Always match the pixel size your form states.

Can I compress to under 30 KB without cropping or changing dimensions?

Yes. Tick "Keep original dimensions" before choosing your file — the whole image is kept and only compressed, scaling down only if needed to fit under 30 KB.

My portal requires an image between 20 KB and 30 KB. Will this work?

Yes. The tool targets just under 30 KB, which sits inside a 20–30 KB window for typical photos. Check the downloaded file size; if it falls below your portal's minimum, start from a sharper, larger original photo.

How do I convert a mobile photo or PNG to a 30 KB JPG?

Upload the PNG or phone photo directly — the tool converts it to a 30 KB JPG automatically, on Android, iPhone or desktop. Nothing is uploaded to a server.

Why is 30 KB a common limit on Indian government and admission portals?

Portals cap file sizes to keep application servers fast and storage cheap. 30 KB is a common ceiling for photo uploads on state recruitment boards, university admissions and KYC forms — always check your form's exact KB and pixel requirements.

Is my image uploaded to a server?

No. ShantiTools compresses the image entirely inside your browser — the file never leaves your device.

Common mistakes

• •Uploading a screenshot — screenshots are already compressed and often produce blocky JPEGs. Use the original photo instead.
• •Ignoring dimensions — a file can be the right KB but the wrong shape. This page sets 350×450 px automatically.
• •Cropping too tightly — leave a small margin around the head and shoulders so the form does not cut the face.
• •Wrong background — busy backgrounds eat KB and can get rejected. Plain white or light works best.

Troubleshooting

The result is still too big

Start with a smaller source file or crop closer to the face. If the form allows a smaller size, try 25 KB.

The result is too small

The source image may be very low resolution. Upload a larger original photo and retry.

My form rejected the upload

Double-check both the KB limit and the pixel dimensions in the form. Some forms also require exact aspect ratios (e.g. 3.5×4.5 cm).
