Nothing is uploaded

The file is processed locally by your browser and never sent to UtilityHub.

Your original stays intact

Every action creates a separate download and leaves the source file unchanged.

Check the result

Open the downloaded file and confirm it meets the destination’s current requirements.

Practical guidance

Use the result with confidence

PDF compression rebuilds document pages at a lower image resolution. It works best for scanned documents; searchable text, forms, links or signatures may not behave like the source, so inspect every page in the output.

Before you finish

  • Page count and order are unchanged.
  • Names, numbers, stamps and signatures remain readable.
  • The file is below the required maximum.

Questions

Why can text look different?

The compressor may render pages as images to reduce size. Use the original when searchable text or interactive fields must be preserved.

Can every PDF reach 100KB?

No. Multi-page or detailed scans may become unreadable before reaching a very small target.

Is the PDF sent to a server?

No. Processing is performed in your browser.
