Autumn is college application season, with early deadlines on or around 1 November for many US schools and similar deadlines elsewhere. Application portals are strict: they accept certain file types, enforce size limits, and sometimes display documents to admissions staff exactly as uploaded. A badly prepared PDF can look sloppy or fail to upload at the last minute.
Check each portal's rules first
Before converting anything, read the requirements for each school and each upload field:
- Accepted file types (often PDF only).
- Maximum file size per upload.
- Page limits for essays, résumés or portfolios.
- Whether documents should be combined into one file or uploaded separately.
Rules differ between portals and even between fields on the same portal. Make a short list for each application.
Convert essays and résumés to PDF
Write in your usual word processor, then export to PDF rather than uploading a .docx. A PDF looks the same on every computer, keeps your fonts, and cannot be accidentally edited. See how to convert Word to PDF, and for résumés specifically, PDF vs DOCX for résumés.
Before exporting, check:
- The word count meets the limit.
- Your name appears where the instructions ask (some ask for it in the header, some forbid it).
- Fonts are standard and readable.
Scan supporting documents properly
Transcripts, certificates, award letters and identity documents often need to be scanned. Use a scanner app on your phone rather than a plain photo; it crops, straightens and saves to PDF. See scanning documents with your phone. Scan at 150 to 200 DPI for text documents; higher makes files large without helping legibility.
Keep files under the size limit
Phone scans and portfolio images can be large. If a file is too big:
- Compress it. Docento.app has a compress tool that works in the browser without uploading your documents, which matters for transcripts and IDs.
- Remove unnecessary pages.
- For portfolios, export images at a sensible resolution before building the PDF.
Our guide to compressing a PDF for application portals covers this in detail.
Combine or split as instructed
If a field asks for one document, combine related pages, such as a two-page transcript, into a single PDF in the right order. See how to combine PDF files. If the portal wants separate uploads, keep them separate.
Name files clearly
Use a clear, professional file name: Lastname-Firstname-Transcript.pdf rather than scan0003.pdf. Admissions staff sometimes see the file name.
Check the final PDF
Open each file before uploading and check that every page is present, upright and readable. Rotate any sideways pages; see how to rotate a PDF page. If a portal shows a preview after upload, look at it.
Takeaway
Read each portal's file rules, export essays to PDF, scan supporting documents with a scanner app at 150 to 200 DPI, compress anything over the limit, and name files clearly. Do it a week before the deadline, not the night before.
