How to reduce a PDF's size for an online form
Online forms for exams, jobs, admissions and government services often accept only small files. Here is how to get under the limit and keep the document readable.
Tools for this: Compress PDF Scan to PDF Merge PDF Split & Organize PDF
1. Check the exact limit
Read the form: it usually says "PDF, maximum 200 KB" or similar. Note whether it wants one PDF for all pages or one file per document.
2. Start from a good scan
Most oversized PDFs are phone photos. Scan the paper with Scan to PDF instead: it straightens the page and removes the shadow, which already makes the file much smaller.
If colour is not needed, choose Black & white. It is usually the biggest saving of all.
3. Compress to the size you need
Open Compress PDF, type the KB limit (for example 200), and save. The tool aims just under the limit and keeps text as sharp as it can.
4. Fix the pages, not just the size
Remove blank or extra pages with Split & Organize. Fewer pages mean a smaller file.
If the form wants everything in one PDF, join the documents first with Merge PDF, then compress.
5. Check before you upload
Open the result and zoom in on names, numbers and seals. If something is hard to read, compress a little less or scan that page again.
