How do I compress a photo to 100 KB without losing clarity?

Upload it above. The tool fits it to 600×800 px and automatically picks the highest JPEG quality that still fits under 100 KB — no quality slider to guess. At 100 KB the compression is visually clean for form photos.

What is 100 KB photo size in pixels?

KB measures file size, not pixel size, so there is no fixed conversion. This page outputs 600×800 px by default. If your form states different pixel or cm dimensions, follow the form, or tick "Keep original dimensions".

My portal asks for a photo between 50 KB and 100 KB. Will this work?

Yes. The tool targets 90–98 KB, which sits inside a 50–100 KB window. Check the downloaded file size against your form's exact minimum and maximum before uploading.

How do I compress a scanned certificate or marksheet to under 100 KB?

Upload the scan and tick "Keep original dimensions" before choosing the file — the whole page is kept and only compressed, so no text, stamp or signature is cropped out.

Can I compress a 5–10 MB phone photo to 100 KB?

Yes. JPG and PNG photos from Android or iPhone work directly in your browser, and the result downloads as a JPEG under 100 KB. If an iPhone HEIC photo won't open, export it as JPG first.

Does the 100 KB file include DPI information?

Yes, the JPEG carries 150 DPI metadata. It doesn't change the pixels, and it doesn't guarantee any portal will accept the file.

Is my image uploaded to a server?

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

Compress Image to 100 KB — 100 KB Photo Size Resizer Online

100 KB is one of the most common upload caps on Indian portals — for photos, marksheets, certificates and KYC documents alike. This tool lands your JPEG just under 100 KB (typically 90–98 KB) so it clears both 'under 100 KB' and '50–100 KB' rules, while keeping far more detail than smaller sizes.

Tips for a clean 100 KB file

•The tool aims for 90–98 KB — safely under the cap, with no wasted quality.
•Uploading a scanned certificate or marksheet? Tick "Keep original dimensions" so text and stamps are never cropped.
•Scan documents in good, even light — shadows and dark edges waste KB that could go into sharpness.
•Keep the original file. If another portal asks for 50 KB or 200 KB later, you will need it.

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 600×800 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 90 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).
