Compress PDF

Maximum compression gives the smallest file — good for documents that will only be read on screen. Balanced is a sensible default for most use cases. Best quality makes a modest size reduction while keeping the document sharp — best if the file will be printed.

If Riqa detects that further compression would not meaningfully reduce the file size, you will be told the file is already well-optimised and offered the original to download. A credit is still used because the operation ran — this is consistent with how all Riqa operations are charged.

No. Text, formatting, and document structure are always preserved. Only image data within the PDF may be downsampled, depending on the quality setting you choose.

You will need to decrypt it first using Riqa's Unlock PDF tool before compressing.

Compressing costs 3 credits.
