Compress Image to 4 MB

Compress an image to 4 MB — roughly what a camera produces, with the excess trimmed away.

Supports JPEG, PNG, WebP, GIF, BMP and more — up to 50 MB

How to compress an image to 4 MB.

The target is preset, so this takes three steps — plus what to expect at 4 MB.

1
Step 1

Upload your image

Click upload or drag and drop any JPEG, PNG, WebP, SVG, or GIF file from your device.

2
Step 2

Target is already set to 4 MB

This page is preset to 4 MB, so there is nothing to type. Choose JPEG or WebP output for the most efficient result at this size.

Step 3

Compare, then download

Press compress and check the result against your original in the slider. Typical of a full-resolution camera JPEG is the realistic pixel budget at 4 MB — download when it looks right.

Getting the best results

Re-encoding a camera JPEG can be free

Camera encoders prioritise write speed. Re-compressing at high quality often trims 30–40% with no visible difference, because you are removing inefficiency rather than detail.

Check what stock libraries require

Stock agencies publish minimum resolutions and often reject visible artefacts. Keep the quality setting high for submissions and verify against their specification.

Compressing an image to 4 MB.

What 4 MB is actually for, what it can hold, and how to get there without wasting quality.

What 4 MB is good for

4 MB is about what a modern camera or phone writes for a single high-quality JPEG. Targeting it means keeping essentially all the useful detail while removing the inefficiency of an in-camera encoder optimised for speed rather than size.

In-camera JPEG compression is deliberately conservative, which leaves real savings available at no visible cost.

Where this size is required

Full-resolution copies of camera files, professional delivery sets, stock photography submissions, and masters for further editing.

What to expect at 4 MB

Essentially full camera resolution with no visible loss — around 24 megapixels for a typical modern sensor.

Frequently asked questions.

Everything you need to know about compressing images to 4 MB.

If storage is a constraint, a high-quality re-encode is usually invisible and saves a third. If you shoot RAW, keep the RAW files and treat JPEGs as derivatives.

No. Compressing to a target size adjusts the encoding, and only reduces dimensions if the target cannot be met otherwise. At 4 MB a full-resolution photo comfortably fits.

If storage is a constraint, a high-quality re-encode is usually invisible and saves about a third. If you shoot RAW, keep the RAW and treat JPEGs as derivatives.

No. The compressor adjusts encoding first and only reduces dimensions if the target cannot be met otherwise, which at 4 MB is not the case for a normal photo.

Because camera encoders prioritise write speed over efficiency. Re-compressing at high quality removes that inefficiency rather than visible detail.

For a photographic JPEG, typical of a full-resolution camera JPEG is the practical ceiling before compression becomes visible. Flat graphics, screenshots, and document scans do considerably better, because they contain less fine detail to preserve.

No. Images are processed on our secure server only to perform the compression and are deleted immediately after your download. They are never stored, shared, or accessed by anyone.
