Client and Vendor Portals
5 MB limitAccounting platforms, legal submission portals, and vendor management systems frequently require uploaded documents to be under 5MB.
LMS and Course Platforms
5 MB limitLearning management systems like Canvas, Blackboard, and Moodle often limit file uploads to 5MB for course materials and assignments.
Mobile File Transfer
Under 5 MB idealSharing PDFs over messaging apps or AirDrop is faster when files are under 5MB. Large files take longer to send and may fail on slow connections.
Document Archiving

How to Compress a PDF to Under 5MB
Open Diwadi
Download and install Diwadi on your Mac or Windows computer. No account required.
Drop Your PDF
Drag your PDF into the app. Diwadi shows the current file size immediately.
Select Compression Level
For most documents, Quality Priority or Balanced compression brings files under 5MB. Only use Maximum for very large files over 30MB.
Check and Save
Diwadi shows the compressed file size. If it is under 5MB, save the file. If not, try a higher compression level.
Choosing the Right Compression Level for 5MB
The right setting depends on your original file size and content type.
Quality Priority
Up to 40% smaller
Best for PDFs already 5-10 MB
Minimal image quality loss. Ideal for reports and documents with a few charts or photos that are close to the 5MB target.
Try this first if your PDF is under 10 MB.
Balanced
Up to 70% smaller
Best for PDFs 10-25 MB
Reduces images and optimizes fonts while keeping text sharp. The best option for most documents targeting 5MB.
Recommended for most 5MB targets.
Maximum Compression
Up to 90% smaller
Best for PDFs over 25 MB
Aggressive compression for very large files with many images. Some visible quality reduction in photos, but text stays clear.
Use for large scanned documents or image-heavy catalogs.
Common Documents That Need 5MB Compression
Annual Reports and White Papers
10-50 MBAnnual reports include high-resolution photos, infographics, charts, and multi-page layouts that push files well past 5MB.
Balanced compression typically brings a 30-page annual report from 15MB to under 5MB while keeping graphs readable.
Product Catalogs and Lookbooks
15-80 MBCatalogs with dozens of product photos and descriptions generate very large PDFs, especially at print resolution.
Balanced or Maximum compression can reduce a 40-page catalog from 30MB to under 5MB. Images stay clear enough for screen viewing.
Multi-Page Scanned Documents
5-50 MBScanning 10 or more pages at 300 DPI produces files that easily exceed 5MB. Medical records, legal documents, and contracts are common examples.
Maximum compression with image downsampling to 150 DPI brings most multi-page scans well under 5MB.
Presentation Decks (20+ slides)
8-40 MBLarge slide decks exported as PDF include full-resolution backgrounds, logos, and graphics on every slide.
Quality Priority compression usually reduces a 20-slide deck from 12MB to under 5MB with no visible quality loss.
User Manuals and Guides
5-30 MBTechnical manuals with screenshots, diagrams, and step-by-step photos grow large quickly, especially when exported from documentation tools.
Balanced compression works well for technical content. Screenshots and diagrams compress efficiently while staying readable.
Portfolios and Design Work
10-100 MBDesign portfolios with high-resolution images, artwork, and project photos often exceed 5MB by a wide margin.
Balanced compression reduces most portfolios to under 5MB. For portfolios over 50MB, Maximum compression is needed.

Tips for Getting Under 5MB
Start with Quality Priority compression
Since 5MB is a more generous target, Quality Priority mode often gets the job done with the least impact on image quality.
Remove unnecessary pages first
If your PDF has blank pages, appendices, or sections you do not need, remove them before compressing. Use Diwadi's PDF split tool to extract only the pages you need.
Check your original file size
If your PDF is 6-10MB, Quality Priority will likely work. If it is 10-25MB, use Balanced. Over 25MB, use Maximum compression.
Compress scanned documents more aggressively
Scanned PDFs are essentially images. They compress much more than text-based PDFs. Use Maximum compression for multi-page scans.
Process multiple files in batch
If you have several documents to compress, drop them all into Diwadi at once. Each file is compressed independently to the smallest possible size.
Keep original files as backup
Always save a copy of your original before compressing. You may need the full-quality version for printing or archiving later.

Can I compress any PDF to exactly 5MB?
Diwadi compresses to the smallest possible size at each compression level. For most PDFs between 6-50MB, Quality Priority or Balanced compression will bring the file under 5MB. Very large PDFs over 100MB may need Maximum compression.
Will compressing to 5MB affect text quality?
No. Text in PDFs is stored as vector data and is not affected by compression. Only embedded images are compressed. Text remains fully searchable and sharp at any compression level.
How do I know if my PDF is under 5MB after compression?
Diwadi shows the compressed file size immediately after processing. You can also check the file size in your operating system's file browser (right-click the file and select Properties on Windows, or Get Info on Mac).
What if my PDF is still over 5MB after maximum compression?
For extremely large PDFs (100MB+), try these steps: remove unnecessary pages using the PDF split tool, then compress. If the document has hundreds of high-resolution images, splitting it into smaller sections and compressing each part can also help.
Is it safe to compress sensitive documents to 5MB?
With Diwadi, yes. All compression happens locally on your computer. Your files are never uploaded to any server. This makes it safe for financial documents, legal papers, and confidential business reports.
Can I compress multiple PDFs to under 5MB at once?
Yes. Drag multiple files into Diwadi and compress them all in batch. Each file is processed independently, so they all get compressed to the smallest possible size.
Does Diwadi work offline?
Yes. Diwadi works completely offline after installation. No internet connection is needed for PDF compression.
What platforms does Diwadi support?
Mac (Apple Silicon and Intel) and Windows (10, 11). Download the version for your operating system from the downloads page.
Which compression level should I use for a 15MB PDF?
For a 15MB PDF targeting 5MB, start with Balanced compression. It typically achieves 50-70% reduction, bringing a 15MB file to 4-7MB. If the result is still over 5MB, switch to Maximum compression.
Is Diwadi free to use?
Yes. PDF compression is free with no limits on file size, number of files, or number of compressions. No account or signup required.
