JPG to PDF with a size cap

Convert JPG to a PDF Under 300 KB

Upload boxes that cap PDFs at 300 KB are common on tender sites, scholarship forms and document repositories. This preset converts your images and automatically tunes JPEG quality until the finished PDF fits under the cap.

The tool opens with the 300 KB preset already applied | nothing is uploaded anywhere.

A PDF built from untouched photos is often five to ten times larger than the cap a portal allows. Re-exporting each image by hand in an editor is slow, and guessing quality values wastes attempts.

This page opens the JPG to PDF tool with a maximum size of 300 KB pre-filled. The builder re-encodes your images at progressively lighter quality until the assembled PDF measures under the cap, then stops at the best quality that fits. Pages, order and orientation controls stay exactly as in the full tool.

Everything happens inside your browser: images are read from disk, encoded locally, assembled with a local PDF library, and the result downloads straight from memory.

What if my PDF still exceeds 300 KB?
The builder steps quality down in six measured passes. If even the lightest pass cannot fit, the result card tells you the best achievable size so you can remove a page or two.
Does text inside scanned images stay readable?
Scans tolerate moderate quality well. The passes start high (0.85) and only go lighter when the cap demands it.
Can I mix JPG and PNG inputs?
Yes. PNGs are converted through the same quality pipeline when a target is set, so mixed batches still land under the cap.
