Compress Image to 150 KB

Compress an image to 150 KB — the lower end of the range a full-width hero image usually wants.

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

How to compress an image to 150 KB.

The target is preset, so this takes three steps — plus what to expect at 150 KB.

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 150 KB

This page is preset to 150 KB, 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. Roughly 1750 × 1750 px is the realistic pixel budget at 150 KB — download when it looks right.

Getting the best results

Choose an image that compresses well

Soft backgrounds, shallow depth of field, and open sky compress far better than dense detail. When a hero is being selected anyway, this is worth factoring into the choice.

Preload the hero

A preload hint tells the browser to fetch the hero immediately rather than waiting to discover it in the markup, which can remove hundreds of milliseconds from Largest Contentful Paint.

Compressing an image to 150 KB.

What 150 KB is actually for, what it can hold, and how to get there without wasting quality.

What 150 KB is good for

150 KB is where a full-width hero starts to look genuinely good. Below it you are usually trading visible quality on wide screens; above it you begin to delay the moment the page becomes usable.

It is the size to reach for when the main image carries the design. A hero at 150 KB is a defensible balance between impact and speed.

Where this size is required

Full-width hero and banner images, landing page headers, above-the-fold photography, and section backgrounds on marketing pages.

What to expect at 150 KB

Photographs hold quality to roughly 1750 × 1750 pixels, or about 3 megapixels — enough for a full-bleed image on most laptop and desktop displays.

Frequently asked questions.

Everything you need to know about compressing images to 150 KB.

Not if it is the page's main image and you preload it. The rule of thumb is that the LCP element should arrive within about 2.5 seconds — at 150 KB that is achievable on typical mobile connections.

WebP if you control the markup, since it delivers more detail at the same 150 KB. Keep a JPEG fallback if you need to support older browsers.

Not for the page's main image, provided you preload it. The target to keep in mind is Largest Contentful Paint completing within about 2.5 seconds.

A preload hint tells the browser to fetch the hero immediately rather than waiting to discover it in the markup, which can remove hundreds of milliseconds from your LCP measurement.

Soft backgrounds, shallow depth of field, and open sky. Dense foliage, crowds, and fine texture need more data, so factor that in when choosing a hero photograph.

For a photographic JPEG, roughly 1750 × 1750 px 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.
