How to jpg to pdf under 150kb
- Add one or more images (JPG, PNG or WebP).
- Each image becomes an A4 page, compressed to the highest quality that keeps the whole PDF under 150KB.
- Check the final file size on the result card.
- Download your under-150KB PDF — ready to upload.

Where a 150KB PDF limit shows up
150KB sits between the two most common caps and appears on state PSC applications, university admission forms and payment-proof uploads. If your portal says "PDF up to 150 KB", this page makes exactly that.
It's enough for two to three clean document pages, or one detailed photo page at good quality.
How the tool stays under 150KB without ruining quality
A PDF's size is almost entirely the images inside it, and image size is controlled by two levers: JPEG quality and resolution. This tool never pushes quality below the level where JPEG compression turns blocky. If the 150KB budget is too tight at full resolution, it reduces the image resolution step by step instead — a slightly soft page reads fine on screen and in print, while a blocky one looks broken.
That is the same approach our exam-photo tools use, and it matters most for multi-page PDFs: the byte budget is shared across every page, so the tool finds the single quality level that fits all pages under 150KB together.
