The common PDF problem
Email and form upload limits are still a real issue. A scanned contract, report, portfolio, or application packet can easily become 20 MB, 50 MB, or larger. The fastest fix is usually PDF compression, but many PDF websites require a full file upload before they can process anything.
If the PDF contains client details, financial data, signatures, or internal notes, upload-based compression may be the wrong default.
Start by checking the target limit
Before compressing, confirm the limit you need to meet. Common targets are:
| Use case | Practical target |
|---|---|
| Email attachment | Under 20 MB |
| Web form upload | Under 10 MB |
| Client portal | Under 25 MB |
| Mobile sharing | Under 5 MB |
Do not compress more than necessary. The goal is a smaller file that still looks readable.
Compression method that keeps files local
Use EaziApps PDF Compressor when you want the PDF to stay in your browser.
- Open the compressor page.
- Choose the PDF from your device.
- Select a quality level.
- Download the compressed result.
- Open the output and check text, signatures, page order, and readability.
Because the work happens in your browser, performance depends on your device. A short PDF usually processes quickly. A large scanned PDF can take longer because every page image needs to be handled locally.
Quality setting guide
Use this starting point:
| Setting | Best for | Tradeoff |
|---|---|---|
| High | Reports, proposals, design documents | Smaller reduction |
| Medium | Most scanned PDFs and forms | Good balance |
| Low | Simple scans or files that only need to be readable | More visible quality loss |
If the file is still too large after medium compression, try splitting the PDF first. Sending two smaller files is often better than making one unreadable file.
Important limitation
Some browser-based PDF compression workflows rasterize pages. That means text may become part of an image and may no longer be selectable. This is acceptable for many scanned forms, but it is not ideal for searchable legal documents, academic PDFs, or documents where copyable text matters.
Always open the output before sending it.
Better results with split and merge
If one appendix or image-heavy section causes most of the size, split the PDF first:
- Use PDF Split to extract the large section.
- Compress only the large section.
- Use PDF Merge to rebuild the final packet.
This keeps the important text-heavy pages cleaner while still reducing the total size.
Bottom line
Compressing a PDF should not automatically mean uploading a private document. For many everyday files, local browser compression is enough. Use the lowest compression level that meets your size target, then check the final PDF before sending it.
