Compress an image to 500 KB

Half a megabyte keeps a photo very close to the original at normal viewing size.

Nothing is uploaded. Your browser does the compression, so the file stays on your device.

Lands under the real limit. We aim a little below it, so the upload goes through first time.

Fast. A 30 second 1080p clip fits into 10 MB in about two seconds on a desktop.

When you need 500 KB

Support tickets, forums, CMS uploads, and email where you want to keep quality.

What to expect

Most photos keep their full pixel size or lose a little, with quality high.

How big a picture fits in 500 KB

Rough pixel sizes at good quality. The tool checks the real result, so treat these as a guide.

What it is	About this many pixels
Detailed photo (landscape, crowd)	1,270 x 850
Typical photo or headshot	1,560 x 1,040
Scan, signature or screenshot of text	2,700 x 1,800

How we hit the number

We try the highest quality that fits. If the picture still will not fit even at a lower quality, we reduce the pixel size a step at a time until it does. Photos are saved as JPEG by default, which every form accepts. You can switch to WebP or PNG with the format menu.

The target we aim for is 485 KB, which is 15 KB under 500 KB, so the file is not turned away over a few bytes.

Questions people ask

Will a screenshot compress well?

Screenshots with text compress best as PNG for sharp edges, or as WebP if accepted.

Limits change. We link the official page wherever there is one, and the safety margin means a small change is unlikely to matter. Last updated 2026-11-09.
