Tips for effective PDF compression

  • Compress each supporting document separately, not the whole dossier
  • Passport photo pages need 120 dpi minimum to stay verifiable
  • Keep the uncompressed original in case an officer requests a reprint
  • Ten pages of dense color scans cannot fit 400 KB: split first
  • Check embassy checklists, some fields cap at 300 KB instead

Frequently Asked Questions

How do I compress a PDF to 400 KB?

Upload the dossier to EasyPDF and pick strong compression. A 4-6 MB scan of mostly text pages compresses to about 400 KB at 100-130 dpi.

Is 400 KB safe for visa documents?

Yes: passport data pages, bank statements and invitation letters stay verifiable at 100-130 dpi. Always keep the uncompressed original in case an officer requests a reprint.

My multi-page file will not reach 400 KB. What now?

Split the PDF so each document travels separately, then compress each part. Ten pages of dense color scans cannot fit 400 KB without becoming unreadable.
