Common App Documents That Exceed the 2 MB Limit
Scanned Official Transcripts
Schools that scan transcripts at 300+ DPI produce PDFs from 3 to 15 MB. Color seals, watermarks, and multi-page documents make files larger than Common App's 2 MB limit.
Drop the transcript into Diwadi and use balanced compression. The seal, text, and watermarks remain readable. A typical 8 MB transcript shrinks to 1-1.5 MB.
Compress TranscriptRecommendation Letters on Letterhead
Scanned recommendation letters from counselors and teachers are 2-5 MB each, especially with colored letterhead logos and handwritten signatures.
Apply balanced compression. The letterhead, signature, and body text all remain clear. A 4 MB letter typically becomes 400-600 KB.
Compress Recommendation LetterArt Supplement Portfolio PDFs
Art portfolios compiled as PDFs contain high-resolution artwork images. A 10-15 piece portfolio can be 30-60 MB, far exceeding any upload limit.
Compress the portfolio PDF with balanced compression to preserve color accuracy and fine detail. A 40 MB portfolio typically compresses to 6-10 MB. For SlideRoom uploads, compress individual images instead.
Compress Portfolio PDFFinancial Aid and Tax Documents
Scanned tax returns, W-2 forms, and bank statements for CSS Profile and IDOC submissions are often 5-15 MB. These contain sensitive personal and financial information.
Compress offline with Diwadi. Your tax returns, bank statements, and Social Security information never leave your computer. A 10 MB document typically shrinks to 1-2 MB.
Compress Financial DocumentsResearch Papers and Writing Samples
Academic papers with embedded charts, graphs, and citations exported as PDF can be 5-20 MB, especially from programs like LaTeX or Google Docs.
Compress the exported PDF to reduce embedded image overhead while keeping text and figures sharp. A 12 MB paper typically becomes 2-3 MB.
Compress Research PaperActivities Resume or CV
Resumes with logos, images, and formatted layouts exported from Canva or design tools can exceed 2 MB, especially with embedded fonts.
Compress the PDF to strip unnecessary font data and reduce image sizes. A 3 MB resume typically becomes 300-500 KB.

Why Compress Common App Documents Offline?
Sensitive Personal Information Stays Private
Common App documents contain Social Security numbers, financial data, addresses, and personal essays. With Diwadi, none of this ever leaves your computer -- no server uploads, no third-party access, no data stored in the cloud.
No File Size or Daily Limits
Online PDF compressors restrict free usage or limit file sizes. During application season, you may need to compress dozens of documents for multiple schools. Diwadi has no daily caps or file limits.
Instant Compression, No Waiting
No upload and download wait times. Compression happens instantly on your computer, even for large portfolio PDFs. Submit your applications faster.
Compress All Documents at Once
Drop your entire application folder into Diwadi -- transcripts, letters, essays, and supplemental materials. Process everything in batch instead of one file at a time.
Works Without Internet (Deadline Insurance)
Internet outages happen at the worst times. Diwadi works completely offline, so you can compress and prepare all your documents even if your connection drops right before a deadline.
Mistakes to Avoid When Uploading to Common App
Waiting until January 1st to compress files
Many students compress files on the night of the deadline. If something goes wrong, there is no time to fix it. Prepare and compress all documents at least a week before each deadline.
Uploading financial documents to free online compressors
CSS Profile and IDOC documents contain tax returns, bank statements, and Social Security numbers. Never upload these to free online tools. Use a local desktop compressor.
Over-compressing art portfolio images
Maximum compression on artwork reduces color accuracy and fine detail that admissions committees evaluate. Use balanced compression for portfolios and test with one image first.
Not verifying the compressed file opens correctly
After compression, open the PDF and scroll through every page. Check that text is readable, seals are visible, and signatures are clear before uploading to Common App.
Using the wrong file format
Common App accepts PDF, DOC, and DOCX for most uploads. If you are submitting a scanned document, always use PDF. JPG and PNG are only accepted for specific art supplement uploads through SlideRoom.

Frequently Asked Questions
What is the Common App file size limit?
Common App has a 2 MB (megabyte) per-file upload limit for most document types, including transcripts, essays, and recommendation letters. Accepted formats are PDF, DOC, and DOCX. If your file exceeds 2 MB, you will see an upload error and need to compress the file first.
How do I compress a PDF to under 2 MB for Common App?
Use a desktop PDF compressor like Diwadi: open the app, drag and drop your PDF, select balanced compression, and save. Most scanned transcripts and recommendation letters compress from 5-10 MB to under 2 MB without visible quality loss.
Why does Common App say my file is too large?
Common App rejects files over 2 MB. Scanned documents, PDFs with embedded images, and Word files with graphics commonly exceed this limit. Check your file size in your file manager -- if it is over 2 MB, compress it before uploading.
Can I compress my transcript without losing readability?
Yes. Balanced compression reduces a scanned transcript from 8 MB to 1-2 MB while keeping all text, school seals, watermarks, and signatures clearly readable. Admissions officers will not notice any difference.
Is it safe to compress financial aid documents online?
No. Financial aid documents contain tax returns, bank statements, and Social Security numbers. Do not upload these to free online compressors. Use a desktop tool like Diwadi that compresses files locally on your computer without sending them to any server.
What compression level should I use for Common App?
Use balanced compression for most documents. This reduces files by 60-80% while maintaining readability. Only use maximum compression for very large scanned transcripts (over 10 MB) or if balanced compression does not bring the file under 2 MB.
Does compressing a PDF change the content?
No. PDF compression reduces internal image quality and removes unnecessary metadata, but the visible text, layout, and content remain the same. Admissions officers will see the same document.
How do I compress an art portfolio for Common App?
Art supplements are typically uploaded through SlideRoom, which allows 10 MB per image. If you are submitting a compiled portfolio PDF, use balanced compression to preserve color accuracy. For individual images, compress each one separately before uploading.
Can my recommender compress their letter before uploading?
Yes. Share Diwadi with your recommender. They can compress their scanned letter on their own computer before uploading it through Common App. This keeps the letter private and under the 2 MB limit.
What do I do if my file is still over 2 MB after compression?
Try maximum compression. If the file is still too large, it likely contains very high-resolution images. Consider re-scanning the document at 200 DPI instead of 600 DPI, or split a multi-page document into separate files and upload them individually.
Does Common App accept Word documents?
Yes. Common App accepts DOC and DOCX files in addition to PDF. However, PDF is recommended because it preserves formatting across all devices. If your Word file is over 2 MB, export it as PDF first, then compress the PDF.
When should I compress my Common App documents?
Compress all documents at least one week before your earliest deadline. This gives you time to request new copies of any document that does not compress well, verify all uploads, and avoid last-minute technical problems.
