Resize Image to 0.5 MB
Half a megabyte is a common limit on upload forms and websites. This page compresses your photo under 0.5 MB with the highest quality that fits. Everything runs in your browser — nothing is uploaded. Need different dimensions instead? Resize or convert.
Why compress to 0.5 MB?
0.5 MB is a common upload limit for blog images, large web graphics and attachments. At that size a JPG photo can be about 1780×1330 pixels at medium quality.
About 1780×1330 px fits
At medium quality a detailed JPG photo of roughly 1780×1330 pixels lands under 0.5 MB; at high quality about 1240×930.
Typical use
0.5 MB limits are common for blog images, large web graphics and attachments.
7× smaller than a phone photo
A 12 MP phone photo is around 3–4 MB, so it must shrink about 7×. The tool lowers quality first and resizes only if needed.
Quality to expect
At 0.5 MB, quality is very good. There is room for a sharp, full-screen photo.
Scans and documents
A scanned A4 page of about 2150×3040 pixels usually fits, because text pages compress far better than photos.
Exact limit, checked
0.5 MB is measured as 524,288 bytes (1 KB = 1,024 bytes), the way most upload forms count it, so the file is never just over.

Half a megabyte is plenty
0.5 MB is about 500 KB. Forms written in megabytes mean the same limit as “500 KB” (or 512 KB if the site counts 1 MB as 1024 KB). Either way, this page keeps your file safely below it.
Room for a good photo. Half a megabyte holds a sharp photo of about 1600–2000 pixels on the long side, more than enough for most forms and web pages.
Need the KB version? The 500 KB page does the same job; use whichever matches the wording of your form.

Frequently asked questions
How many pixels fit in 0.5 MB?
For a detailed JPG photo, about 1780×1330 at medium quality or 2410×1810 at low quality. Simple graphics and scans can be much larger.
What quality will a 0.5 MB 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 0.5 MB the same as 500 KB?
Most forms count 1 MB as 1,024 KB (524,288 bytes). The tool uses that count, so the result fits under the limit.
Should I use JPG or WebP for 0.5 MB?
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 0.5 MB?
Very large or detailed images may not reach 0.5 MB by quality alone. Resize it first (for example to 1780 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.
