About this tool
Even though Gmail allows up to 25 MB attachments and Outlook a similar range, corporate mail gateways, mailing lists, and older systems often reject anything larger than a few megabytes. Compressing a PDF to around 1 MB is a safe, universal bet — small enough for the strictest recipients, large enough to preserve readable pages. This landing tunes the PDF compressor for a ~1 MB target. Everything runs in your browser.
FAQ

Almost always — even strict gateways typically allow 5–10 MB.
Yes, use our 500 KB PDF landing for tighter caps.
Text becomes flat images; if you need editable output, keep the original.
No. Email-oriented PDF compression stays in your browser; Konvert does not receive the PDF.
