Compress an image to 1 MB

One megabyte is the safe size for MMS texts and the sweet spot for emailing a stack of photos.

  • 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 1.00 MB. We aim for 970 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 1.00 MB

MMS and SMS, email with several photos, and many social upload fields.

What to expect

A 12 megapixel phone photo usually fits at around 2000 pixels wide with little visible change.

How big a picture fits in 1 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)1,800 x 1,200
Typical photo or headshot2,200 x 1,470
Scan, signature or screenshot of text3,810 x 2,540

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 970 KB, which is 30 KB under 1.00 MB, so the file is not turned away over a few bytes.

Questions people ask

A 4K PNG to 1 MB?

Yes. PNG is converted to JPEG by default for this, since lossless PNG of a big picture rarely fits.

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.
