About this tool

Five megabytes is a large but reasonable size for a design review: several color pages, a portfolio excerpt, a long notebook scan. It is the wrong goal if a form asked for 100 KB. Use it to stop a 40 MB photo PDF from being rude while the images stay recognizable. Start with Recommended and go stronger only if you are still well above 5 MB.

Compress PDF to 5 MB is processed entirely on your device. Your original file remains untouched, and nothing is ever uploaded to a server or saved in the cloud.

  • No upload: the 5 MB goal is applied here, and the PDF is not posted to a compressor.
  • Speed: processing happens instantly on your device with no upload or download delays.
  • Quality: you can check your file before saving, and the original remains unchanged.
