Email attachment limits (Gmail 25 MB, Outlook 20 MB) prevent sending large PDFs directly. Here are the best free solutions.
Go to pdfeditor.onl/compress-pdf. Use Strong compression. Most PDFs can be compressed to well within email limits. Download and attach the compressed version.
Tip: Strong compression reduces image resolution and stream sizes. For document PDFs without many images, even Strong compression maintains excellent readability.
Upload the large PDF to Google Drive. Right-click → Share → Anyone with the link → Copy link. Paste the link in your email body instead of attaching the file. The recipient downloads it from Drive.
If the PDF must be attached (not shared via link), split it into smaller parts at pdfeditor.onl/organize-pdf. Send multiple emails with one part each.
Option 2 (Google Drive link) is best for legal documents — it ensures the recipient receives the exact file without any compression quality trade-off.
Yes — compression and splitting at pdfeditor.onl are completely free.
