Resize Image to 600 KB
600 KB is enough for a full 1920×1080 photo at high quality — no visible compression, but a fraction of the original phone file. Everything runs in your browser — nothing is uploaded. Need different dimensions instead? Resize or convert.
Why compress to 600 KB?
Many sites cap images at 600 KB — typically for blog images, large web graphics and attachments. That leaves room for roughly a 1920×1440 JPG photo.
About 1920×1440 px fits
At medium quality a detailed JPG photo of roughly 1920×1440 pixels lands under 600 KB; at high quality about 1340×1010.
Typical use
600 KB limits are common for blog images, large web graphics and attachments.
6× smaller than a phone photo
A 12 MP phone photo is around 3–4 MB, so it must shrink about 6×. The tool lowers quality first and resizes only if needed.
Quality to expect
At 600 KB, quality is very good. There is room for a sharp, full-screen photo.
Scans and documents
A scanned A4 page of about 2330×3290 pixels usually fits, because text pages compress far better than photos.
Exact limit, checked
600 KB is measured as 614,400 bytes (1 KB = 1,024 bytes), the way most upload forms count it, so the file is never just over.

Full HD without visible compression
1920×1080 at 600 KB is roughly quality 85–90 for a typical photo. Side by side with the original, most people can't tell them apart.
Galleries. A lightbox that opens images full screen needs them large. 600 KB keeps each one sharp while a gallery of 30 still totals under 20 MB.
Resize and compress. Resize to 1920 wide with the 1920×1080 page first; compressing a 4000-pixel photo straight to 600 KB costs more quality.

Frequently asked questions
Is 600 KB enough for a Full HD photo?
Yes. A 1920×1080 photo at 600 KB is high quality, with no compression you can easily see.
How many pixels fit in 600 KB?
For a detailed JPG photo, about 1920×1440 at medium quality or 2610×1950 at low quality. Simple graphics and scans can be much larger.
What quality will a 600 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 600 KB the same as 600,000 bytes?
Not quite. Most forms count 1 KB as 1,024 bytes, so 600 KB is 614,400 bytes. The tool uses the same count, so a file it marks as under 600 KB is accepted.
Should I use JPG or WebP for 600 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 600 KB?
Very large or detailed images may not reach 600 KB by quality alone. Resize it first (for example to 1920 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.
