Resize Image to 120 KB
120 KB is enough for a clean photo about 800 pixels wide — a good size for sharing in chats and for link preview images. This page compresses to fit. Everything runs in your browser — nothing is uploaded. Need different dimensions instead? Resize or convert.
Why compress to 120 KB?
Many sites cap images at 120 KB — typically for profile photos and document uploads with a strict limit. That leaves room for roughly a 860×640 JPG photo.
About 860×640 px fits
At medium quality a detailed JPG photo of roughly 860×640 pixels lands under 120 KB; at high quality about 600×450.
Typical use
120 KB limits are common for profile photos and document uploads with a strict limit.
30× smaller than a phone photo
A 12 MP phone photo is around 3–4 MB, so it must shrink about 30×. The tool lowers quality first and resizes only if needed.
Quality to expect
At 120 KB, quality is good. Plenty for web pages, email and on-screen viewing.
Scans and documents
A scanned A4 page of about 1040×1470 pixels usually fits, because text pages compress far better than photos.
Exact limit, checked
120 KB is measured as 122,880 bytes (1 KB = 1,024 bytes), the way most upload forms count it, so the file is never just over.

| Scanned A4 document | about 1040×1470 px |
| Reduction from a 12 MP phone photo | about 30× |
| Output format | JPG (best for photos), WebP or PNG |
| Typical use | Profile photos and document uploads with a strict limit |
Compress an image to 120 KB in 3 steps

Photos for sharing and previews
Link previews. When you paste a link into WhatsApp, Slack or social media, the site's preview image (Open Graph image) is downloaded first. Small preview images load reliably; very large ones are sometimes skipped.
Preview size. The usual preview is 1200×630. Compressing that to about 120 KB keeps it sharp at the size it is shown.
Sharing in chats. Messaging apps recompress photos anyway. Sending a 120 KB version saves data and still looks good on a phone.
Also: 125 KB, JPEG under 120 KB, 150 KB.

Frequently asked questions
What size should a link preview image be?
1200×630 pixels is standard. Keep it well under 300 KB — around 100–150 KB is ideal.
How many pixels fit in 120 KB?
For a detailed JPG photo, about 860×640 at medium quality or 1160×870 at low quality. Simple graphics and scans can be much larger.
What quality will a 120 KB photo have?
Good. Plenty for web pages, email and on-screen viewing. The tool keeps the dimensions where it can and lowers compression quality first, so faces and text stay readable.
Is 120 KB the same as 120,000 bytes?
Not quite. Most forms count 1 KB as 1,024 bytes, so 120 KB is 122,880 bytes. The tool uses the same count, so a file it marks as under 120 KB is accepted.
Should I use JPG or WebP for 120 KB?
JPG is accepted everywhere and is the safe choice for forms. WebP holds about 30% more detail at the same size, ideal for websites that support it.
Why is my file still over 120 KB?
Very large or detailed images may not reach 120 KB by quality alone. Resize it first (for example to 860 pixels wide) with the resizer, then compress again.
Are my images uploaded anywhere?
No. They are read and compressed by your own browser and never leave your device. You can disconnect from the internet once the page has loaded and it will still work.
