Compress PDF for Email
Reduce PDF file size for Gmail, Outlook, and portal uploads — when to compress, when to split, and free tools on FileToolsHub.
Email providers and HR portals reject oversized PDFs even when the content is fine. Image-heavy scans, exported slide decks, and merged invoices are the usual culprits — not “too many words.”
Compress PDF on FileToolsHub optimizes those heavy pages. If the file is still too large, split unused sections out or merge fewer pages first.
Step-by-step
Clean pages before compressing
Delete blank or duplicate pages with Edit PDF Pages to avoid compressing junk.
Open edit pdf pagesSplit if still too large
Use Split PDF to send chapters or appendices as separate attachments.

Tips
- Keep an uncompressed master for printing; email the compressed derivative.
- Scanned color photos shrink more than text-only pages — expect bigger wins on camera scans.
- For phone photos not yet in PDF, use JPG to PDF or Images to PDF, then compress.
