Compress an image to 3 MB

A 3 MB limit appears on some government, bank and insurance portals and older mail systems.

The target is already set to 3 MB. The tool tries the highest quality first and lowers it step by step until the file fits. It shrinks the pixel size only when quality alone cannot get under the limit. It aims slightly below 3 MB, counting 1 KB as 1,000 bytes, so the file also passes on systems that count 1,024 bytes.

What fits in 3 MB

As a JPG or WebP, a typical photo of close to the full resolution of a phone photo fits in 3 MB. Screenshots, logos and scans of text behave differently: flat colors compress very well, and fine texture or noise compresses poorly. If the file cannot reach 3 MB at a reasonable size, the list tells you and shows the smallest result.

Tips for reaching 3 MB

  • A photo from a recent phone can be over 5 MB. Compression to 3 MB is mostly invisible.
  • A HEIC photo from an iPhone can be converted to JPG and compressed to 3 MB in one step.
  • Compress from your original file. Compressing a copy that was already compressed loses more detail.

Frequently asked questions

How do I compress an image to 3 MB?

Add the image. The target is already 3 MB, so the tool finds the highest quality that fits and shows the result. Download it when it looks right.

Will the image still look good at 3 MB?

Usually yes for the sizes listed on this page. If the original has far more pixels than 3 MB can hold, the tool reduces them too, so a very large photo may look smaller but not blocky.

Can I compress a HEIC photo to 3 MB?

Yes. Add the HEIC file and keep JPG as the output. The tool converts it and reduces it to the target. Some browsers load a small decoder for HEIC first.

What happens if my image is already under 3 MB?

Nothing is changed. The tool keeps your original file when it already fits and no resize is requested.
