“Your message couldn’t be sent — attachment too large.” Email limits are real: Gmail ~25 MB, Outlook ~20 MB, many corporate gateways less. Here’s the fastest path under the limit.
Try these in order (stop when it fits)
- Lossless compress. Open Compress PDF, pick Recommended. Often a 30–60% cut with zero visible change. Many files clear the limit here.
- OCR-then-compress for scans. A scanned PDF is giant images. Run OCR PDF, then compress Strong — 40 MB → under 2 MB is common.
- Downsample images. If still big, use a stronger level (targets ~150 DPI) — fine for screen/email.
- Split it. Still over? Split the PDF into part 1 / part 2 and send two emails.
- Send a link instead. Last resort: upload to your own cloud and share the link.
Don’t do this
- Don’t screenshot every page into a new PDF — it bloats and destroys text.
- Don’t email a ZIP of a single PDF — corporate filters often block ZIPs; it barely shrinks an already-compressed PDF.

FAQ
Will text get blurry? Lossless never touches text. Only aggressive image downsampling softens photos — preview before sending.
