PDF Compressor

Make large contracts, drawings, reports and scanned letters small enough to email and upload. Photos and scans inside the file are resized to the resolution you choose; the text stays sharp and searchable.

Step 2

Choose the level

Advanced settings
Files are compressed on your device. Nothing is uploaded. Text, links, bookmarks and form fields stay in place in every level except Smallest.
How to use

Compress a PDF in four steps

The file never leaves your computer. It is read, compressed and saved again by your browser.

  1. Add the PDF filesDrop one or more PDFs on the box, or choose them. Up to 20 files of up to 300 MB each.
  2. Choose the levelBalanced is right for most files. Light keeps more detail for print; Strong and Smallest make the file as small as possible.
  3. CompressEach file is read and compressed on your device. The list shows the size before and after.
  4. Check and downloadOpen a file to check the quality, then download it, or download all the files as one ZIP.
What it does

Where the space is saved

Most large PDFs are large because of what is inside them, not because of the text.

Photos and scans resized

Each image is resized to the resolution you choose, worked out from the page it sits on, and saved again as JPEG.

Repeats merged

Fonts and logos repeated in merged documents are kept once, and data no page uses is removed.

Hidden data removed

Editing history, embedded metadata and page thumbnails are dropped. The content you see is unchanged.

Text kept

Text, links, bookmarks and form fields stay in place, so contracts remain searchable, including in Root Cause Intelligence.

FAQ

Questions about the PDF compressor

Short answers on quality, privacy and file types.

Will the text in my PDF still be searchable?

Yes, at the Light, Balanced and Strong levels. Only the images inside the file are resized and saved again, so text, links, bookmarks and form fields stay as they are. The Smallest level turns each page into one image, so text can no longer be selected or searched.

Are my files uploaded anywhere?

No. The PDF is read and compressed by your browser on your own device. Nothing is sent to a server, so it is safe for contracts and commercial documents.

Which level should I choose?

Balanced suits most files and keeps photos sharp on screen. Use Light for drawings you will print, Strong when an email or portal has a size limit, and Smallest for scanned letters that are only images anyway.

Why did a file hardly get smaller?

Files made mostly of text and vector drawings are already compact; the tool only saves space where there are photos, scans, repeated fonts or unused data. If the result is not smaller, the original is kept.

Can it open password protected PDFs?

No. Remove the password in your PDF reader first, compress the copy, and protect it again if needed.
