Common App & Coalition App Document Upload — File Size Guide
Most document upload failures on Common App are file size issues. Fix them here before they block your submission.
Common App serves 900+ universities; Coalition App serves another 150+. Both have per-slot file size limits that are smaller than most applicants expect. A scanned transcript from a school copier routinely comes out at 8–15 MB — several times over the Common App's main essay slot limit of 500 KB. The most common support request from applicants is "why did my file upload fail?" — the answer is almost always file size. Compress your documents here before starting your application.

Common mistakes to avoid
- Uploading a 15 MB scanned transcript: school office copiers scan at 300 DPI color by default; the resulting file is 8–20 MB. Compress to under 5 MB with the tool above.
- PDF with embedded fonts that don't render in Common App's viewer: use Print to PDF (not Save As PDF) to flatten fonts before uploading — this prevents text from showing as boxes or blank.
- Assuming all slots have the same limit: the main essay slot is 500 KB, but school-specific supplemental essay slots may allow more — always check each slot's tooltip before uploading.
- Uploading a Word .docx file: Common App requires PDF for most document types. .docx files are silently rejected on most slots without a clear error message.
Frequently asked questions
- What is the maximum file size for Common App essay uploads?
- The Common App main essay slot accepts PDF files up to 500 KB. School-specific supplemental essay slots vary by institution and may allow up to 5 MB. Always check the tooltip or file requirements shown next to each upload field.
- Why does Common App say my file failed to upload when it's only 8 MB?
- The main essay slot caps at 500 KB — 8 MB is 16 times over the limit. An 8 MB file is typically a scanned document or a Word file exported with embedded graphics. Compress it to under 500 KB using the PDF compressor above.
- Should I use Print to PDF or Save As PDF for my Common App essay?
- Use Print to PDF. It flattens all fonts and formatting into a universal PDF that renders correctly in any viewer — including Common App's built-in document preview. "Save As PDF" from Word can embed fonts that don't render correctly on the Common App side, showing blank text boxes.
- What is the difference between Common App and Coalition App document requirements?
- Both platforms accept PDF documents and cap individual slot uploads at around 500 KB. The difference is which universities use which platform — most of the same schools accept both, but a few use only one. Upload requirements at the slot level are similar.
- Can I upload a Word document to Common App, or does it have to be PDF?
- Common App requires PDF for document uploads. Word .docx files are rejected — often silently, without a clear error message. Convert your essay to PDF using Print to PDF before uploading.
- My transcript is 12 MB — how do I compress it without losing text readability?
- Use the PDF compressor above targeting 5 MB. A 12 MB transcript is typically a color scan at 300 DPI; the compressor converts to grayscale and reduces DPI, bringing it to under 3 MB while keeping all printed text clearly readable. If your school submits transcripts via Naviance or Parchment, you may not need to upload a transcript yourself at all.
