How to Compress a PDF Invoice for Email (Free)
Invoices and receipts as PDFs can be oversized. Compress before emailing clients — free, no account, preserves text quality.
Invoices generated from accounting software are often 2–5 MB due to embedded fonts and graphics. Compressing them before sending keeps email threads clean and attachment sizes reasonable.
Steps
Go to fixmypdf.in/tools/compressor. Upload the invoice PDF. Choose Medium compression (preserves text quality for invoices). Download and attach to email.
Best Compression Level for Invoices
Medium: text remains sharp and legible, logos and graphics are clear, file size reduced by 40–60%. Invoices do not need print-quality resolution for email review, so Medium is the right balance.
Watermarking After Compression
To mark invoices as PAID once settled: compress first, then add a "PAID" text watermark using the watermark tool. Return a watermarked copy to the client as a receipt.
Privacy
Invoice PDFs often contain financial data and client details. FixMyPDF's local processing means this data never reaches a third-party server.
