Compress PDF for Email (small size)
Shrink a PDF to fit email attachment limits with an aggressive size-focused preset. Free and private — the PDF is processed in your browser, never uploaded.
Email attachment limits are usually 20–25 MB. This preset re-renders PDF pages at reduced image quality (50%) and resolution (1.2×), which typically shrinks scanned or image-heavy PDFs by 70–90% — enough to attach to any email. Processing happens locally in your browser.
🔒 Compression runs in your browser — your PDF is never uploaded. Note: pages are rasterised, so text becomes part of the image.
How it works
- Choose a PDF file.
- Adjust the quality and resolution sliders.
- Click Compress, then download the smaller PDF.
Frequently asked questions
Why is my PDF too big to email?
Scanned pages and embedded photos inflate PDFs quickly. Re-rendering them at lower quality and resolution removes most of that weight.
Will the text stay selectable?
No — pages are re-rendered as images to achieve the size reduction, so text becomes part of the image. Keep the original if you need selectable text.
