The compressor analyzes your PDF and applies multiple optimization techniques: image downsampling, object deduplication, metadata cleanup, and stream compression. The level you choose determines how aggressively these are applied.
For most use cases, yes. Our compressor uses the same techniques as desktop tools (image optimization, deflate compression). The advantage is you don't need to install anything.
Currently, the tool processes one PDF at a time. For multiple files, compress each one individually — it only takes a few seconds each.
