Compress PDF files for email and web
Email services and online forms often cap uploads at 10–25 MB. Use this compress PDF online tool to reduce PDF file size so your resumes, invoices, or onboarding packets upload without errors. It’s perfect when you need to shrink PDF for email upload or for LMS, HR, and legal portals.
How does this PDF compressor work?
We inspect every page, recompress embedded images, remove unused objects, and clean metadata to deliver the smallest possible file while keeping text sharp. For scanned documents, reducing image DPI and JPEG quality yields dramatic savings without hurting readability.
Which compression level should I choose?
- Low compression – Best for printing and graphic-heavy decks. Minimal change to visual quality.
- Balanced – Ideal for general sharing, web publishing, and email. Keeps text crisp with smaller files.
- Strong – Maximum size reduction for strict upload limits. Expect more aggressive image compression.
Is my PDF safe?
Yes. Files are transmitted over HTTPS, processed temporarily, and deleted shortly after compression. Password-protected PDFs aren’t supported yet, but unencrypted files never leave the secure environment longer than necessary.
Use cases
- Submitting applications or forms to government and university portals.
- Sending scanned contracts, NDAs, or receipts via email without bounce-backs.
- Reducing marketing reports, brochures, and pitch decks for sharing online.
- Compressing multi-page scans from copiers that output 50 MB+ PDFs.
FAQ – Compress PDF
Is this PDF compressor free to use?
Yes. Compress unlimited PDFs online for free without watermarks.
Will compressing a PDF lower its quality?
Images may be recompressed, but text layers stay crisp. Choose Low compression if you need print-level quality.
How much can you reduce the file size?
It depends on the original. Scanned PDFs often shrink by 50–80%, while already-optimized files might only drop slightly.
Do you store my PDF?
No. Files are processed temporarily and deleted shortly after the download is ready.
Can you compress scanned PDFs with images?
Yes. Those typically benefit the most thanks to downscaled, recompressed images.
Why is my PDF not shrinking much?
Some PDFs already use optimized images. Try the Strong compression level or verify if the file already meets the size limit.
What’s the maximum PDF size supported?
PDFs up to 60 MB per upload are supported. Larger documents should be split before compressing.
