Compress an image to 3 MB

Three megabytes is a common limit for uploads on classifieds, rentals and real estate sites.

  • 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 3.00 MB. We aim for 2.91 MB, 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 3.00 MB

Listing photos on marketplaces and property sites, and support portals.

What to expect

Most phone photos keep their full resolution at high quality.

How big a picture fits in 3 MB

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)3,110 x 2,070
Typical photo or headshot3,810 x 2,540
Scan, signature or screenshot of text6,610 x 4,410

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 2.91 MB, which is 90 KB under 3.00 MB, so the file is not turned away over a few bytes.

Questions people ask

My photo is 8 MB. Will it lose quality?

Very little. We first try lowering the quality slightly, which is hard to see, and only reduce the pixel size if that is not enough.

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.
