Email attachments
Compress PDF for email when the attachment is too large
Most email providers cap attachments around 25 MB. BotMart shrinks office PDFs and scans so you can send them as normal attachments.
When Gmail, Outlook, or a company mail server rejects your PDF, the fix is almost always a smaller file—not a different email app. Compress in the cloud, download the result, then attach it to your message.
Why compress a PDF before emailing?
- Fit provider limits — Gmail and many providers block attachments above about 25 MB; corporate servers can be stricter.
- Faster for recipients — Smaller downloads on mobile data and slow connections.
- No desktop software — Upload from phone or laptop, download a lighter PDF, attach as usual.
How to compress a PDF for email
- Sign in (free account).
- Open the PDF compressor and upload your file.
- Choose a quality preset (screen or ebook for email; print only if you need higher fidelity).
- Download the smaller PDF and check the size on disk.
- Attach it to your email—or send a cloud link if it is still over your provider's limit.
Scanned documents and photo PDFs
Scans and image-heavy PDFs are often the largest. Compression helps a lot for those. Text-only office PDFs are usually already small; if yours is huge, it may contain embedded images or high-resolution pages.
FAQ
What size can I email?
Aim well under 25 MB for Gmail and similar providers. Some workplaces allow only 10 MB—compress until you are safely under the limit.
Will the PDF still open normally?
Yes. Output is a standard PDF. Compression can reduce image detail on scans; pick a higher-quality preset if print fidelity matters.
How long are files stored?
Uploads and outputs are removed automatically within 24 hours. Only you can access your jobs while they exist.
