How to use a free online PDF compressor
Upload the PDF, choose the right mode, wait for processing, and download the result.
Step 1. Upload the PDF
Add up to 4 PDF files and make sure each file fits the current size limit.
If the document is very large, start by choosing the most important files first rather than uploading everything at once.
Step 2. Pick a mode
Start with strict when the PDF should look as close to the original as possible.
Move to balanced or maximum only when you need stronger size reduction.
Step 3. Download the result
When processing ends, download the optimized PDF as soon as it is ready.
Because this is a processing tool, not long-term storage, it is better to keep your final file in your own storage.
