Smaller PDFs

Compress PDFs so plans, reports and invoices are easy to email and upload

Reduce the size of a PDF so it will go through email and upload forms, without installing desktop software. Choose how hard to compress, convert to grayscale if colour is not needed, and see the before and after size when it is done.

Compress PDF

Pick a file, choose a compression mode and, if colour is not needed, convert to grayscale.

Why PDFs get too big to send

Scanned service agreements, photographed forms and image-heavy reports can run to many megabytes. Email systems and online portals often limit attachment size, and large files are slow to upload, share and store. A smaller file is easier for everyone who has to handle it.

How it works

How to compress a PDF

  1. Open Compress PDF from Document Tools.
  2. Choose the PDF you want to shrink.
  3. Pick a compression mode: Aggressive (best balance), Good Quality, Extreme (smallest size) or Screen (maximum compression). Tick Convert to Grayscale if you do not need colour.
  4. Click Upload & Compress PDF and wait for the file to finish processing.
  5. Check the original size, new size and reduction, then download the compressed PDF.
  6. Open the compressed file and make sure it is still readable before you send it.
Why it matters

Built for the files providers actually send

Four modes, one choice

Start with Aggressive for a balance of size and quality. Move to Good Quality when appearance matters, or to Extreme or Screen when size matters most.

Grayscale option

If a document does not need colour, converting to grayscale can reduce its size further.

See what you saved

The result shows the original size, the compressed size and the percentage reduction, so you know whether it worked.

Honest when it cannot help

If a file is already well compressed, the tool tells you no reduction was achieved instead of pretending it worked.

Accountability

Every action is tied to the staff member who ran it and timestamped. Output files are automatically deleted after a set retention window, so you stay audit-ready without the file clutter.

Common questions

Compress PDF FAQ

Which compression mode should I use?

Start with Aggressive, which is the default and aims for the best balance of size and quality. If the result is still too large, try Extreme or Screen. If text or images look too rough, use Good Quality.

Will compressing reduce the quality of my PDF?

It can. Stronger modes trade image quality for a smaller file. Open the compressed file and check it before you send it, and keep your original.

What if the file does not get any smaller?

Some PDFs are already well compressed. When that happens the tool says no size reduction was achieved. You can still download the result, or try a stronger mode.

What does Convert to Grayscale do?

It removes colour from the file. It suits documents where colour is not important, and it can reduce file size further.

Does it replace my original file?

No. You download a new compressed PDF and your original is untouched.

Who can use it?

Access is controlled in Admin Tools. You decide which staff can use Document Tools.
