Frequently Asked Questions
How much can I compress my PDF?
The final reduction depends on the file contents. PDFs with large images usually shrink the most, while mostly-text documents often keep a smaller but still useful size reduction.
Will compression affect text quality?
Text stays sharp and readable. Compression focuses mainly on embedded images and document structure so the file becomes easier to share without making the text blurry.
Which compression level should I choose?
Use the recommended middle level for most documents. Higher compression is useful for email attachments and uploads, while lighter compression keeps more image detail.
Is it safe to upload my PDF?
Files move over HTTPS and go through short-retention processing. Temporary files are scheduled for cleanup after the workflow finishes.
When should I compress a PDF?
Compression is useful before sending files by email, uploading documents to forms or portals, or sharing PDFs on websites where smaller files load faster.
