Compress WebP to 100 KB
100 KB of WebP gives a sharp, mid-size web photo. This page converts any image to WebP and keeps it just under 100 KB. Everything runs in your browser — nothing is uploaded. Need different dimensions instead? Resize or convert.
Why compress to 100 KB?
A 100 KB target is usually set for profile photos and document uploads with a strict limit. A WebP photo of around 940×700 pixels fits, with good quality.
About 940×700 px fits
At medium quality a detailed WebP photo of roughly 940×700 pixels lands under 100 KB; at high quality about 650×490.
WebP stretches the limit
WebP packs about 30% more detail into 100 KB than JPG, but check that the site you upload to accepts .webp files.
36× smaller than a phone photo
A 12 MP phone photo is around 3–4 MB, so it must shrink about 36×. The tool lowers quality first and resizes only if needed.
Quality to expect
At 100 KB, quality is good. Plenty for web pages, email and on-screen viewing.
Scans and documents
A scanned A4 page of about 1130×1600 pixels usually fits, because text pages compress far better than photos.
Exact limit, checked
100 KB is measured as 102,400 bytes (1 KB = 1,024 bytes), the way most upload forms count it, so the file is never just over.

Product photos as WebP
Shops and catalogues benefit most from WebP: dozens of product photos per page, each 100 KB instead of 150 KB as JPEG, adds up to much faster loading.
Pixel guide: about 850–900 pixels wide at high quality.
Check your platform. Most modern shop builders and CMSs accept WebP uploads. If yours doesn't, use JPEG to 100 KB.
Transparent product cut-outs stay transparent in WebP.

Frequently asked questions
Can I upload WebP to my online shop?
Most modern platforms accept it. If yours doesn't, compress to JPEG instead.
How many pixels fit in 100 KB?
For a detailed WebP photo, about 940×700 at medium quality or 1270×950 at low quality. Simple graphics and scans can be much larger.
What quality will a 100 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 100 KB the same as 100,000 bytes?
Not quite. Most forms count 1 KB as 1,024 bytes, so 100 KB is 102,400 bytes. The tool uses the same count, so a file it marks as under 100 KB is accepted.
Should I use JPG or WebP for 100 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 100 KB?
Very large or detailed images may not reach 100 KB by quality alone. Resize it first (for example to 940 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.
