How to put photos or scans into one PDF under a size limit

Portals often ask for one PDF with several pages, for example both sides of an ID card or every page of a marksheet, and cap the file at a few hundred KB.

Steps

1. Open Image to PDF, or a preset page such as JPG to PDF under 100 KB or under 300 KB.
2. Add the photos in the order you want the pages, and move them up or down if needed.
3. Choose A4 or Letter for documents, or Fit to image to keep each photo’s shape.
4. Set Max KB to your portal’s limit. The tool lowers the image quality evenly across the pages until the whole PDF fits.
5. Download the PDF and check each page.

Tips for sharp pages at small sizes

• Shoot documents flat, in daylight, and fill the frame with the page.
• Crop away the table or floor around the document first with Crop image.
• Fewer pages means more KB for each one, so leave out anything the portal didn’t ask for.

Already have several PDFs? Merge them into one, then compress the result.
