Compress an image to 150 KB

A hundred and fifty kilobytes is a common cap for product photos and profile pictures.

  • 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.
Where are you sending it?

Custom size 150 KB. We aim for 146 KB, a small safety margin so the file never lands just over.

Sent to our servers: 0 bytes. It all happens in this tab.

When you need 150 KB

Marketplace thumbnails, school and HR portals, and website images that need to load fast.

What to expect

A photo keeps about 800 to 1000 pixels of width at good quality.

How big a picture fits in 150 KB

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

What it isAbout this many pixels
Detailed photo (landscape, crowd)700 x 470
Typical photo or headshot850 x 570
Scan, signature or screenshot of text1,480 x 990

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 146 KB, which is 5 KB under 150 KB, so the file is not turned away over a few bytes.

Questions people ask

Is this a good size for a website photo?

Yes. Pages with images around 150 KB load quickly on phones. Choose WebP for the smallest file if your site accepts it.

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.
