How to jpg to pdf under 1mb
- 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 1MB.
- Check the final file size on the result card.
- Download your under-1MB PDF — ready to upload.

Where a 1MB PDF limit shows up
"Under 1MB" is the classic email-attachment and LMS-upload rule, and plenty of portals cap PDFs at exactly 1MB. A single phone photo often exceeds it on its own — so a multi-photo PDF needs the size managed for you.
At 1MB nearly everything fits at high quality: think 6–10 photographed pages, or fewer pages at near-original sharpness.
How the tool stays under 1MB 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 1MB 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 1MB together.
