Compress Image to 120 KB — 120 KB Photo Size Resizer Online

Where a 120 KB limit shows up

• Scanned certificates, marksheets, and passbook uploads
• Attested and notarised document verification portals
• Bank statement and KYC document pages
• Portals with a 100–120 KB document upload cap

Tips for a clean 120 KB file

• •For scanned documents, tick Keep original dimensions before choosing the file — the whole page compresses under 120 KB without losing edges, stamps, or signatures.
• •Round office stamps in blue or purple ink compress badly. Scan in colour at this size so the stamp stays legible.
• •Do not sharpen the image before uploading. Sharpening adds edge noise that makes the file larger and the scan look artificial.
• •If a portal allows up to 120 KB, aim for 110–115 KB output — some servers measure in kibibytes and reject files sitting exactly at the cap.

Frequently asked questions

How do I compress an image or photo to exactly 120 KB?

Upload your photo above and the tool lowers JPEG quality step by step until the file lands under 120 KB, then hands you the download. No sliders, no guessing — the whole thing runs in your browser in a few seconds.

What are the best pixel dimensions for a 120 KB photo or document?

For a portrait photo, 640×860 px at 150 DPI keeps faces sharp at this size. For a full document page, keep the original scan dimensions and let the compression do the work — detail matters more than the pixel count.

How do I reduce a file to 120 KB without cropping or stretching?

Tick the Keep original dimensions option before selecting your file. The tool then compresses the whole image as-is — same shape, same edges — and only adjusts quality to reach 120 KB.

Can I compress scanned certificates, marksheets, or bank passbook photos to 120 KB?

Yes — that is one of the most common uses of this page. Photograph or scan the document in good light, upload it here with Keep original dimensions ticked, and the text, stamps, and signatures stay readable at 120 KB.

Can I convert smartphone photos, PNG, or WEBP images to a 120 KB JPG?

Yes. Upload any JPG, PNG, WEBP, or phone camera photo (including HEIC shots saved as JPG) and the tool converts and compresses it to a 120 KB JPG in one step.

Why do portals reject my 120 KB upload even when the file size is correct?

Usually one of three reasons: the file is not a JPG (rename alone does not convert it), the aspect ratio does not match the portal's expected shape, or the server measures in kibibytes so a file at exactly 120.0 KB tips over. Compressing to 110–115 KB with the correct format avoids all three.

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 640×860 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 100 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).
