Resize Image to 800 KB
800 KB holds a detailed photo around 2000 pixels wide — big enough to view full screen on most monitors, small enough to send ten in one email. Everything runs in your browser — nothing is uploaded. Need different dimensions instead? Resize or convert.
Why compress to 800 KB?
800 KB is a common upload limit for blog images, large web graphics and attachments. At that size a JPG photo can be about 2220×1670 pixels at medium quality.
About 2220×1670 px fits
At medium quality a detailed JPG photo of roughly 2220×1670 pixels lands under 800 KB; at high quality about 1550×1160.
Typical use
800 KB limits are common for blog images, large web graphics and attachments.
4.5× smaller than a phone photo
A 12 MP phone photo is around 3–4 MB, so it must shrink about 4.5×. The tool lowers quality first and resizes only if needed.
Quality to expect
At 800 KB, quality is very good. There is room for a sharp, full-screen photo.
Scans and documents
A scanned A4 page of about 2690×3800 pixels usually fits, because text pages compress far better than photos.
Exact limit, checked
800 KB is measured as 819,200 bytes (1 KB = 1,024 bytes), the way most upload forms count it, so the file is never just over.

Photos that are still big, but send easily
Email maths. Most mail services cap a message at 20–25 MB, and attachments grow by about a third when sent. Ten photos at 800 KB is about 11 MB on the wire — well inside.
Full-screen viewing. At 2000 pixels wide the photo fills a laptop or Full HD monitor with detail to spare.
Keep the date. If you want to keep when a photo was taken, untick "Remove EXIF" before compressing — otherwise it is stripped with the rest of the metadata.

Frequently asked questions
Does compressing remove the date a photo was taken?
Only if 'Remove EXIF metadata' is ticked. Untick it to keep the date and camera details.
How many pixels fit in 800 KB?
For a detailed JPG photo, about 2220×1670 at medium quality or 3010×2260 at low quality. Simple graphics and scans can be much larger.
What quality will a 800 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 800 KB the same as 800,000 bytes?
Not quite. Most forms count 1 KB as 1,024 bytes, so 800 KB is 819,200 bytes. The tool uses the same count, so a file it marks as under 800 KB is accepted.
Should I use JPG or WebP for 800 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 800 KB?
Very large or detailed images may not reach 800 KB by quality alone. Resize it first (for example to 2220 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.
