JPEG + Smart + 1280px for 150KB target

Compress Image to 150KB | MiniPx — Free, Fast & Private

150KB is a common upload limit for profile photos on professional networks, content management systems, and online forms. MiniPx makes it easy to compress images to this target while maintaining good visual quality.

For most photos: JPEG format, Smart preset, 1280px max width produces files of 80-200KB. If over 150KB, switch to Tiny preset or reduce to 800px width. The Smart preset at 1280px typically produces excellent quality.

At 150KB, images look sharp enough for profile pictures, blog thumbnails, and form uploads. The quality difference from the original is minimal on screen — only noticeable when comparing side-by-side at full zoom.

MiniPx shows the exact compressed size so you can adjust settings until you hit the 150KB target. The real-time preview lets you verify quality before downloading.

All processing is private and browser-based. Your profile photos and documents are never uploaded to any server.

Frequently asked questions

What settings hit 150KB?

JPEG + Smart + 1280px for most photos. Reduce to 800px or use Tiny preset if still over 150KB. Photos with simple backgrounds compress more easily than complex scenes.

Is 150KB enough for a profile photo?

Yes. At 1280px wide, a 150KB JPEG looks excellent as a profile picture. Most platforms display profile photos at 200-400px, so 1280px input is more than sufficient.

Can I batch compress to 150KB?

Yes. Apply the same settings to all images and check each output size. Complex images may need individual adjustment.

Is this free?

Yes. MiniPx is completely free with no limits on file count, file size, or features. No account needed.
