Quick answer
Make the PDF smaller, but do not sacrifice readability.
A PDF that is under the size limit is not useful if names, certificate text, stamps or signatures become unreadable. Reduce file size carefully and always open the final PDF before uploading.
Why PDF files become too large
Most large PDFs are made from high-resolution scanned photos. A single mobile photo can be several MB, and a PDF made from many such photos can quickly cross portal upload limits.
Digital PDFs created from text are usually smaller. Scanned certificates, ID proofs and image-heavy files need more careful preparation.
- Large scanned photos increase PDF size.
- Extra blank or duplicate pages add unnecessary size.
- High-resolution images may not be needed for form upload.
- Compression has limits if the file is already optimized.
Clean the PDF before compression
Before compressing, check whether the file has pages you do not need. Removing pages and using smaller images often gives a better result than compression alone.
- Delete blank or duplicate pages.
- Crop photos before converting to PDF.
- Use only required certificates or pages.
- Keep the original file as backup.
