Is 150 KB enough for a full A4 page?

For reading on screen, yes. For a page that will be printed again at full size, a 300 KB or larger cap gives a better result.

What if my scan is a PDF?

This tool works with JPG and PNG images. Export or screenshot the page as an image first, then compress it here.

Is my image uploaded to a server?

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

150 KB is where you stop making trade-offs. A full A4 page scan holds its small print, and a portrait keeps enough detail to be printed at passport size without looking soft.

How it works

Upload any JPG or PNG from your phone or computer.
We fit it to 700×900 px and tune JPEG quality until the file stays under 150 KB. Prefer your photo's own shape? Tick Keep original dimensions before choosing a file — nothing is cropped.
Download and upload it straight to the form.

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

Tips for a clean 150 KB file

•For an A4 page, 700×900 px is roughly 90 DPI. That is fine on screen; if the document will be re-printed, ask whether a larger cap is allowed.
•Turn off any 'document mode' filter on your phone scanner app for legal papers — it can erase faint but important pencil markings.

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 700×900 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 120 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).
