Compress PDF
Reduce the size of one or many PDFs. Add a batch and each file is compressed and downloaded separately.
This quality level is applied to every file in the batch.

Frequently asked questions
Can I compress multiple PDFs at once?
Yes. Add several PDFs and they are compressed one after another, right from your browser. Each file gets its own download link as it finishes, and you pick a single quality level that applies to the whole batch.
Why are the files processed one at a time instead of all together?
Processing sequentially keeps each file within the per-job limits, gives you clear per-file progress, and lets the others continue even if one file fails. You do not have to wait and re-upload — just add the batch once and the tool works through it.
What happens if one file fails?
Only that file is marked failed with a reason; every other file in the batch still compresses and stays available to download. You can remove the failed one or try again.
Will compression reduce quality?
Higher compression reduces size more and may soften images slightly. Choose a lighter setting (Printer or Prepress) to keep more detail, or Screen for the smallest files.
Why did my file not get much smaller?
PDFs that are mostly text are already compact. The biggest savings come from documents with large or high-resolution images.
How many PDFs can I compress in one batch?
You can line up several files in the browser. Daily usage limits still apply per your plan — sign in or upgrade for higher limits, or use the Falcon PDF desktop app for large bulk jobs.
