Why forms ask for a PDF under 200 KB
Job portals, scholarship and university applications and many government forms limit each uploaded document, often to 200 KB, so their servers stay fast and storage stays cheap. A phone scan of a single page is often 1 to 3 MB, so it has to be made 5 to 15 times smaller before the form accepts it.
What happens to your PDF
- The pictures inside the PDF (scans, photos) are made smaller and saved at a lower quality. Text, links and form fields stay as they are.
- If scanned pages or diagrams would turn blurry, they are made sharp black and white instead, and photos keep their color.
- If that is still not enough, each page is saved as one image at the highest resolution that still fits under 200 KB. The text then looks the same but can no longer be selected; the result tells you when this happened.
- With Black and white on, scanned pages are stored as pure black and white, which keeps letters sharp in far fewer bytes. Color stamps and photos turn black and white too.
If your PDF is already under 200 KB, you get it back unchanged.
If your PDF will not go under 200 KB
- Turn on Black and white if it is a text document.
- Upload only the pages the form asks for; every page adds size.
- Check whether the form takes a bigger file and set that size on the compress PDF page (300 KB, 500 KB or any number).
- If the form wants a photo instead of a PDF, use the image compressor.
