Compress Documents for Visa Application
Reduce PDF and Image Size to Meet Visa Portal Upload Limits
Visa portals have strict file size limits -- typically 1-6 MB per document. Scanned passports, bank statements, and supporting documents often exceed these limits. Compress them offline without uploading sensitive documents to any server.

Common Mistakes When Compressing Visa Documents
Using online compressors for sensitive documents
Uploading passports and bank statements to free online tools means your sensitive data passes through third-party servers. Use a desktop tool instead.
Over-compressing until text is unreadable
Maximum compression with very low DPI can make passport text and stamps unreadable. Always preview the compressed document. 150 DPI is usually the safe minimum.
Submitting wrong file format
Some portals only accept PDF, others only JPG. Check the portal requirements before compressing. Diwadi can also convert between formats.
Not checking file size after compression
Always verify the compressed file size meets the portal limit before attempting upload. Save time by checking first.
Scanning at unnecessarily high resolution
Scanning at 600 DPI when 300 DPI is sufficient creates files that are 4x larger. Scan at 300 DPI and compress to 150 DPI for uploads.
Visa Document Compression Checklist
- Check the visa portal's maximum file size per document
- Check accepted file formats (PDF, JPG, PNG)

- Compress each document to under the size limit
- Preview compressed documents to ensure text is readable
- Verify passport numbers and dates are clearly visible

- Keep original uncompressed copies as backup
- Name files according to portal requirements
- Test upload with one document before submitting all
Frequently Asked Questions
How do I compress a PDF for visa application?
Use a desktop PDF compressor like Diwadi. Open the app, drop your PDF, select balanced or maximum compression, and save. Most scanned documents compress from 5-10 MB to under 1-2 MB without visible quality loss.
Is it safe to compress visa documents online?
Online compressors require uploading sensitive documents (passports, bank statements) to external servers. For visa documents, desktop tools like Diwadi are safer because files never leave your computer.
What is the maximum file size for USCIS?
USCIS allows up to 6 MB per document for most online submissions. However, some specific forms may have lower limits. Use balanced compression to get documents under 4 MB for a safe margin.
How small can I compress a scanned passport?
A color scanned passport page (typically 3-8 MB at 300 DPI) can be compressed to 200-500 KB at 150 DPI while keeping all text, photos, and stamps clearly readable.
Will compression affect the quality of my visa documents?
Balanced compression preserves text sharpness and keeps images clear. Passport text, stamps, and photos remain fully readable. Only extreme compression at very low DPI may affect readability.
What DPI should I use for visa document scans?
Scan at 300 DPI for the original copy. When compressing for upload, 150 DPI is sufficient for on-screen viewing and meets most visa portal requirements. Text remains perfectly readable at 150 DPI.
Can I compress multiple visa documents at once?
Yes. With Diwadi, you can drag and drop multiple files or an entire folder. All documents are compressed in batch, which saves time when preparing a complete visa application.
What file format should I use for visa documents?
Most visa portals accept PDF for multi-page documents and JPG for photos. Check your specific portal requirements. Diwadi can compress both PDF and image files.
How do I compress bank statements for visa?
Drop your bank statement PDF into Diwadi and select balanced compression. Multi-page bank statements with logos and formatting typically compress from 10 MB to 1-2 MB. Your financial data stays on your computer.
Why does my visa portal reject my document even after compression?
Common reasons: the file is still too large (check the exact limit), wrong file format (some portals only accept PDF), file is corrupted during compression (try again with a different compression level), or the portal has dimension requirements for photos.
