JPG to PDF under 100 KB

From photos to a compact PDF

Phone photos of documents are big, and portals often want a single PDF under 100 KB. Converting the photos to a PDF first and then compressing it wastes quality twice. This tool does both in one step: it scales and compresses the page images so the finished PDF lands under your target.

Each image becomes one page in the order you added it. On A4, landscape photos get landscape pages. After the PDF is built, its real size is checked, and if it came out above the target the tool tightens the settings and builds it again.

How to convert JPG to PDF under 100 KB

1. Add the images in page order. JPG, PNG, WebP or HEIC. Add page 1 first; the list shows the order.
2. Set the target size. 100 KB is preset; use the quick buttons for 200, 300 or 500 KB.
3. Choose page size and colour. A4 suits most forms. Tick grayscale for printed documents.
4. Make the PDF. Download it when the result shows a size under the target.

Settings explained

Page size

A4 fits each image on a standard page; “Same as image” makes each page the image’s own shape.

Grayscale

Often halves the size of document scans with no loss of legibility.

Several documents, several PDFs

If a portal asks for each certificate separately, make one PDF per document instead of one large file, so each has the full size budget.

Get better results from phone photos

Photograph documents flat, in daylight, filling the frame. Crop away the table around the page before adding it. A clean, tightly cropped photo compresses much better than one with shadows and background.

Troubleshooting

The pages are in the wrong order

Choose Clear and add the images again in the right order.

“Could not reach the target”

Use grayscale, fewer pages, or a higher limit if the portal allows.
