Resize image to 45 KB

45 KB is enough for either a very clean portrait or a small scanned document. Which one you should aim for depends on whether the field is labelled photo or document — the two need completely different framing.

Target size
31–45 KB

420×560px · 31–45 KB

How it works

  1. Upload any JPG or PNG from your phone or computer.
  2. We fit it to 420×560 px and tune JPEG quality until the file lands between 31 and 45 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 45 KB limit shows up

  • Mid-range exam form photo fields
  • Small scanned certificates
  • Employer document submission portals

Tips for a clean 45 KB file

  • •For a document at this size, scan rather than photograph. A flat scan compresses to half the size of a phone photo of the same page.
  • •If the text in your scan looks fuzzy after compression, increase the scan resolution and try again rather than lowering it.

Frequently asked questions

Is 45 KB enough for a scanned certificate?
For a single flat page, yes. Multi-page or handwritten documents with faint ink usually need 100 KB or more to stay readable.
Should I use JPEG or PNG?
JPEG. Almost every Indian portal expects JPG, and PNG files of a photo are several times larger at the same visual quality.
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 420×560 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 40 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).
