Compress WebP to 500 KB
500 KB of WebP keeps large photos and artwork at near-original quality. This page converts to WebP and keeps the file just under 500 KB. Everything runs in your browser — nothing is uploaded. Need different dimensions instead? Resize or convert.
Why compress to 500 KB?
A 500 KB target is usually set for blog images, large web graphics and attachments. A WebP photo of around 2100×1570 pixels fits, with very good quality.
About 2100×1570 px fits
At medium quality a detailed WebP photo of roughly 2100×1570 pixels lands under 500 KB; at high quality about 1470×1100.
WebP stretches the limit
WebP packs about 30% more detail into 500 KB than JPG, but check that the site you upload to accepts .webp files.
7.2× smaller than a phone photo
A 12 MP phone photo is around 3–4 MB, so it must shrink about 7.2×. The tool lowers quality first and resizes only if needed.
Quality to expect
At 500 KB, quality is very good. There is room for a sharp, full-screen photo.
Scans and documents
A scanned A4 page of about 2540×3590 pixels usually fits, because text pages compress far better than photos.
Exact limit, checked
500 KB is measured as 512,000 bytes (1 KB = 1,024 bytes), the way most upload forms count it, so the file is never just over.

Big, detailed images in WebP
Near-original. Most phone photos fit in 500 KB as WebP at full or near full resolution with no visible difference.
Digital art and illustrations with flat colours and sharp lines compress especially well in WebP — often better than both JPEG and PNG.
Where WebP isn't accepted (some forms and older software), use JPEG to 500 KB instead.
Batch. Convert a whole folder at once and download a ZIP.
Nearby: 300 KB. Plain conversion: PNG to WebP.

Frequently asked questions
Will a photo look the same at 500 KB WebP?
Almost always, at normal viewing size — 500 KB is generous for WebP.
How many pixels fit in 500 KB?
For a detailed WebP photo, about 2100×1570 at medium quality or 2850×2130 at low quality. Simple graphics and scans can be much larger.
What quality will a 500 KB photo have?
Very good. There is room for a sharp, full-screen photo. The tool keeps the dimensions where it can and lowers compression quality first, so faces and text stay readable.
Is 500 KB the same as 500,000 bytes?
Not quite. Most forms count 1 KB as 1,024 bytes, so 500 KB is 512,000 bytes. The tool uses the same count, so a file it marks as under 500 KB is accepted.
Should I use JPG or WebP for 500 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 500 KB?
Very large or detailed images may not reach 500 KB by quality alone. Resize it first (for example to 2100 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.
