Most email services cap attachments at 10-25 MB. Compressing a PDF to under 10 MB makes it email-friendly — typically reducing size by 60-90% with no visible loss.

Email services and corporate mail servers impose strict size limits — 10 MB on most, 25 MB on Gmail. Scanned documents and image-heavy PDFs often exceed these limits. Compressing to email-friendly sizes ensures delivery without bouncing.

The compressor analyzes the PDF structure, downsamples high-resolution embedded images to email-appropriate resolution, re-encodes them efficiently, and strips redundant metadata. Text and vector content are preserved losslessly.

• Emailing large PDFs to clients or colleagues.
• Sending scanned documents via email.
• Sharing reports, invoices, or contracts by email.
• Meeting Gmail/Outlook attachment limits.
• Reducing PDF size for corporate email systems.
• Preparing PDFs for email marketing campaigns.
• Sharing PDF forms with limited bandwidth.

Email-optimized PDFs compress images to screen resolution — fine for reading on phones and laptops. Text stays sharp (vector content is lossless). For print-quality, use the general PDF compressor.

• Embedded images are downsampled — print quality may suffer.
• Scanned PDFs compress dramatically; text PDFs less so.
• Very small PDFs (under 1 MB) may already be email-friendly.
• Encrypted PDFs must be unlocked first.
• Some PDFs are already optimized and won't shrink much.

• Output PDF opens in every browser, reader, and OS.
• Text stays searchable and selectable.
• Editable in Adobe Acrobat, PDF-XChange, Foxit.
• Accepted by Gmail, Outlook, Yahoo, and corporate email.
• Standard PDF — no special software needed.

• Most email services cap at 10-25 MB.
• Scanned PDFs compress dramatically (60-90%).
• Text stays sharp (vector content is lossless).
• For larger savings, use target-size variants (5 MB, 2 MB).
• Batch-compress up to 50 MB at once.

Use the target-size variants (5 MB or 2 MB) for more aggressive compression.

Text looks blurry

Text should stay sharp (vector). If blurry, the PDF was likely scanned.

Images are pixelated

Email-optimized PDFs compress images to screen resolution. For higher quality, use the general PDF compressor.
