A 40 MB phone scan will bounce off Gmail, Outlook caps, and many government forms. Compression fixes that — if you pick the right quality and understand that browser compress often rasterizes pages. SortMyFile Compress PDF runs locally with quality presets or a target size in KB so you can aim for email-safe files without uploading the scan.
Which PDF compression level should you choose for email?
Start with Recommended for everyday email. Use Extreme only when a portal demands tiny files and you can accept blur. Use Low when the PDF will be printed or stamped. If the portal publishes an exact KB limit, switch to Target size (KB) instead of guessing presets.

What quality do you lose when compressing a PDF for email?
Browser compress typically re-embeds pages as images. Selectable text and crisp vector logos may disappear. Keep the original searchable PDF if you still need Cmd/Ctrl+F. After extreme compress, OCR PDF can restore a searchable layer if the scan is still readable.
How do email size caps differ from portal KB limits?
Gmail-style caps are often around 25 MB for the whole message. University and government uploads frequently demand 100–500 KB for a single scan. Those are different problems — use target KB for portals and gentler presets for email when clarity matters.
Do files leave your device when you compress a PDF?
Compression runs in your browser. SortMyFile does not store compressed or original PDFs on an upload API for this tool. That matters when the attachment is an ID proof or bank statement.
