How to jpg to pdf under 300kb
- 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 300KB.
- Check the final file size on the result card.
- Download your under-300KB PDF — ready to upload.

Supported formats
This tool accepts JPG, PNG, WebP (multiple) as input and gives you a PDF under 300KB as output. Files are processed in seconds and never stored — we keep nothing once you have your result.
Where a 300KB PDF limit shows up
A 300KB PDF cap shows up on college admission portals, court e-filing systems and document-update forms. It's also a frequent scanner frustration: office scanners at 300 DPI produce PDFs far over 300KB, and this tool rebuilds them from your photo at exactly the size the form accepts.
At 300KB, two to four document pages keep very good quality — the budget only feels tight for dense photo scans.
How the tool stays under 300KB 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 300KB 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 300KB together.
