Readability matters
Exact compression depends on the original file. Scanned documents usually compress differently from text PDFs. If the result is blurry or still too large, try a higher target, rescan around 150 DPI, or split a multi-page PDF.
Before you upload
- Check the official portal requirement before processing.
- Preview names, dates, seals, signatures, and marks.
- Keep the original file until your application is accepted.

Common upload errors solved
Scanned certificate text is blurry
Scan at a slightly lower resolution (150 DPI) or save in greyscale before compression to preserve readability.
File is still slightly over 100KB
If the source file has multiple pages or image scans, try a lower target or split the file if allowed by the portal.
Privacy and file handling
This workflow uploads the selected file to the processing service. Files are handled automatically and removed from processing storage after the configured one-hour retention period. Use a service appropriate for the sensitivity of the document and keep the original file.
