Resize Image to 80 KB
80 KB is a realistic budget for the main image on a mobile page — the one that decides how fast the page feels. This page compresses to fit it. Everything runs in your browser — nothing is uploaded. Need different dimensions instead? Resize or convert.
Why compress to 80 KB?
Many sites cap images at 80 KB — typically for profile photos and document uploads with a strict limit. That leaves room for roughly a 700×520 JPG photo.
About 700×520 px fits
At medium quality a detailed JPG photo of roughly 700×520 pixels lands under 80 KB; at high quality about 490×360.
Typical use
80 KB limits are common for profile photos and document uploads with a strict limit.
45× smaller than a phone photo
A 12 MP phone photo is around 3–4 MB, so it must shrink about 45×. The tool lowers quality first and resizes only if needed.
Quality to expect
At 80 KB, quality is fine for small display. Good for thumbnails, profile photos and forms.
Scans and documents
A scanned A4 page of about 850×1200 pixels usually fits, because text pages compress far better than photos.
Exact limit, checked
80 KB is measured as 81,920 bytes (1 KB = 1,024 bytes), the way most upload forms count it, so the file is never just over.

| Photo at medium quality | about 700×520 px |
| Photo at low quality | about 950×710 px |
| Scanned A4 document | about 850×1200 px |
| Reduction from a 12 MP phone photo | about 45× |
| Output format | JPG (best for photos), WebP or PNG |
| Typical use | Profile photos and document uploads with a strict limit |

The first image a visitor sees
Page speed. The largest image near the top of a page is often what Google's speed measure (Largest Contentful Paint) waits for. Keeping it under about 80–100 KB on mobile is one of the easiest speed wins.
Serve a mobile-sized version. A phone screen is about 400 points wide — 800–1080 pixels at 2–3× density. Resize to that width, then compress to 80 KB.
Avoid text in images. Words baked into a photo show compression blur first. Put headlines in the page's HTML instead.

Frequently asked questions
How small should a mobile hero image be?
Around 80–150 KB for a photo sized to the phone's width. Smaller is faster, but check it still looks clean.
How many pixels fit in 80 KB?
For a detailed JPG photo, about 700×520 at medium quality or 950×710 at low quality. Simple graphics and scans can be much larger.
What quality will a 80 KB photo have?
Fine for small display. Good for thumbnails, profile photos and forms. The tool keeps the dimensions where it can and lowers compression quality first, so faces and text stay readable.
Is 80 KB the same as 80,000 bytes?
Not quite. Most forms count 1 KB as 1,024 bytes, so 80 KB is 81,920 bytes. The tool uses the same count, so a file it marks as under 80 KB is accepted.
Should I use JPG or WebP for 80 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 80 KB?
Very large or detailed images may not reach 80 KB by quality alone. Resize it first (for example to 700 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.
