FAQ
About this tool
How and why to compress PDF
Many services limit attachment size, and PDFs with many images may exceed the limit. Online compression helps quickly reduce a document before sending to email, CRM or government portal without complex settings and software installation.
Step-by-step workflow
- Upload the PDF that needs to be reduced.
- Select compression level: low, medium or high.
- Download the lighter file and use it for distribution or upload.
Where this is useful
- Sending reports and acts via email (10–20MB limit).
- Uploading documents to government services, tender platforms, corporate portals.
- Preparing an archive for a client or internal storage.
- Compressing scans before merging or publishing on a website.
Quality tips
If the document consists of photos, reduce their resolution before uploading — this way even high compression will preserve readability. Keep a backup copy of the original to repeat compression with different settings if needed. After reduction, you can additionally merge files or split them into parts using other OKDOCS tools.
