Compress Image to 150KB

Fit a 150KB limit with room left for detail.

KB
Advanced (optional): exact pixels or minimum KB

Many forms ask for pixels as well as KB. Leave empty if yours does not. Examples are common sizes only – always use the size your form states.

When 150KB is the number

150KB is a mid-size limit used for profile photos on some marketplaces, certificate uploads and CMS media fields. It keeps about 700 × 900 pixels of a portrait, which holds up on a laptop screen.

Example. A photo of a printed A4 letter is often 1.5–3 MB. At 150KB the body text is typically legible when you zoom to 100%, though not crisp enough to read from a thumbnail.

Quick tips

  • For text, photograph in portrait orientation so the page fills the frame.
  • If you need to share the file on WhatsApp too, send it as a document so it is not compressed again.
  • For website images, 150KB is a reasonable upper limit per image, but see the website guide for dimensions.

Common slip-ups

  • Choosing 150 when a form says 1.5 MB (1,500KB). That is ten times more space.
  • Uploading an image with a transparent background converted to black. Add white borders in Advanced options if needed.

Questions about: Compress Image to 150KB

Is 150KB okay for a website hero image?

It works for modest widths. For full-width banners aim for 100–200KB at 1600 pixels wide and test on mobile.

Why is the result smaller than 150KB?

The tool picks the best quality that fits under your limit, so it can come out slightly below.

Can I compress a PNG logo here?

Yes, but the result becomes a JPG, which has no transparency. Use white borders or keep the PNG for logos.

About the Compress Image to 150KB tool

This page reduces an image to 150KB or less. That size works well for web pictures, blog images and many document uploads. The tool searches for the highest JPG quality that fits, so the picture stays as detailed as the limit allows.

How to use the Compress Image to 150KB tool

  1. Tap “Select Images” and choose your JPG, PNG, WebP or HEIC file.
  2. The size box is already set to 150. Change it only if your form states a different limit.
  3. Leave the width and height empty for web images so the picture keeps its original proportions.
  4. Press the green button, check the Before and After sizes, then download the file (or the ZIP if you added several).
