Resize image to 40 KB

A comfortable middle ground. Enough detail for a printed admit card, small enough for strict portals.

400×500px · 3040 KB

How it works

  1. Upload any JPG or PNG from your phone or computer.
  2. We fit it to 400×500 px and tune JPEG quality until the file lands between 30 and 40 KB.
  3. Download and upload it straight to the form.

Everything runs on your device — your image is never sent to a server.

Where a 40 KB limit shows up

  • University portals
  • Bank application forms
  • Recruitment boards

Tips for a clean 40 KB file

  • Check whether the form measures the limit in KB or KiB — our output clears both.
  • Save the original file too. If a portal later asks for a larger version you will need it.

Frequently asked questions

Is 40 KB enough for a passport-style photo?
Yes. At 400×500 px, 40 KB holds plenty of detail for both on-screen checks and admit-card printing.
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 400×500 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 35 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).

फ़ोटो का साइज़ KB में कैसे कम करें

  • यह पेज आपकी फ़ोटो को 30–40 KB और 400×500 पिक्सेल में बदल देता है।
  • ऊपर बॉक्स पर टैप करके अपनी फ़ोटो चुनें — कुछ ही सेकंड में तैयार फ़ाइल डाउनलोड कर लें।
  • स्क्रीनशॉट की जगह असली फ़ोटो इस्तेमाल करें, इससे क्वालिटी बेहतर रहती है।
  • फ़ोटो आपके डिवाइस से बाहर नहीं जाती और यह टूल बिलकुल मुफ़्त है।
