FAQ

Frequently asked questions

It depends on the content of your PDF. Files with many high-resolution images can often be reduced by 60–80%. Text-heavy PDFs without images will see a smaller reduction of around 10–30%. Maximum compression mode provides the greatest size reduction at a slight cost to image quality.
Yes. All file transfers use SSL/TLS encryption. Your uploaded PDF and the compressed output are stored in a secure, isolated environment and are permanently deleted from our servers within 1 hour of being processed. We never read, share, or sell your file content.
You can compress PDF files up to 50MB in size. This covers the vast majority of PDF documents. If your file is larger, consider splitting it into smaller parts before compressing.
For most purposes, Balanced is the best choice — it significantly reduces file size while keeping images looking crisp. Use Maximum when you need the smallest file possible (e.g. email attachments with strict size limits). Choose Light when the PDF contains important photos or artwork where quality must be preserved.
No. Text, fonts, and vector elements are not degraded by our compression process. Only embedded raster images are resampled to reduce file size. The PDF remains fully searchable and text remains perfectly sharp at all zoom levels.
