How This Tool Works

This PDF Size Converter allows you to change the file size of your PDF. You can upload a PDF file and select your desired size in KB or MB. Then choose whether you want to reduce or increase the file size.

If you select Reduce Size, the tool will try to make the file smaller. For exact compression, advanced server-based processing is required.

If you select Increase Size, the tool will add extra data to match the selected size (when the original file is smaller).

All processing happens inside your browser. Your file is not uploaded to any server, so your data remains private and secure.
