How to jpg to pdf under 100kb
- 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 100KB.
- Check the final file size on the result card.
- Download your under-100KB PDF — ready to upload.

This tool accepts JPG, PNG, WebP (multiple) as input and gives you a PDF under 100KB as output. Files are processed in seconds and never stored — we keep nothing once you have your result.
Where a 100KB PDF limit shows up
A 100KB PDF cap is common on bank KYC uploads, scholarship portals and e-district services — anywhere a form says "upload PDF, max size 100 KB". It's also the classic "jpg to pdf less than 100kb" search: you have a photo of a document and the portal insists on a small PDF.
One or two document pages fit comfortably at this size. The tool shares the 100KB budget across all pages, so fewer pages means sharper output.
How the tool stays under 100KB 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 100KB 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 100KB together.
