PDF too large to send by email? Compress it in seconds. PDFico reduces file size in your browser without uploading to any server. Works with Gmail, Outlook, Yahoo, and every other email provider.
Compress PDF for Email — FreeEvery email provider has a maximum attachment size. If your PDF exceeds the limit, it will bounce or the provider will replace it with a download link. Here are the most common limits.
Go to the Compress PDF tool and drop your PDF file or click to browse.
For most email attachments, the "Balanced" setting works perfectly. It reduces file size significantly while maintaining readable quality. If you need the absolute smallest size, select "Maximum compression".
The compressed PDF is ready to attach to your email. The tool shows you exactly how much smaller the file is, so you can verify it fits within your provider's limit.
Sending a contract, invoice, or financial report? Your files never leave your device. Other compression tools upload your documents to their servers first.
Nothing looks more unprofessional than a watermarked PDF attachment. PDFico never adds watermarks, even on the free tier.
Because compression happens locally in your browser, there is no upload or download wait time. Your compressed PDF is ready in seconds.
Compress PDFs on your laptop, tablet, or phone. PDFico runs in any modern browser with no software to install.
PDFs become large when they contain high-resolution images, embedded fonts, or scanned pages. A scanned 10-page document can easily reach 30-50 MB. Compression optimises these elements to bring the file size down.
Image-heavy PDFs typically shrink by 40-70% with balanced compression. A 30 MB scanned document could compress to 10-15 MB. Text-heavy PDFs with few images see smaller reductions of 5-15%.
With the "Balanced" setting, quality loss is minimal and usually unnoticeable in email attachments. Text remains perfectly sharp. Only high-resolution photos may show slight softening when zoomed in.
If the compressed file still exceeds your email limit, consider using the Split PDF tool to send it in multiple parts, or remove unnecessary pages first.
