Will compression affect the text quality in my PDF?

No. Text is vector-based and is not affected by compression. Only raster images and redundant metadata are optimized, so your text stays sharp and fully readable.

How much smaller will my file get?

Results depend on the content. PDFs with many high-resolution photos can shrink by 70-80%, while text-heavy documents typically see smaller reductions.

Is there visible quality loss on the High compression setting?

High compression applies aggressive image optimization that may cause a slight reduction in image sharpness. For print-quality documents, we recommend Medium or Low.

Can I compress a PDF that has already been compressed?

Yes, but the additional gains will be minimal since redundant data has already been removed in a previous pass.

My file is larger than 100 MB — what should I do?

Use the PDF Page Manager to remove unnecessary pages first, then compress the reduced file. Premium plans also offer higher size limits for large documents.

Is PDF Compress Pro free to use?

Yes, single-file compression is free. Batch processing and priority handling for large files are available on premium plans.
