Why compress PDF for email?
Email attachment limits are one of the most common frustrations when sharing documents. Whether you're sending a contract to a client, submitting homework, or sharing a report with your team, oversized PDFs can stop you in your tracks. AskPDF's compression tool is specifically optimized for email — it targets the sweet spot between file size and readability so your recipients can open and read everything without issues. Most email providers cap attachments at 20-25MB, and our tool consistently gets files well under that threshold.
