How to use this tool

  1. Add one PDF. The upload limit is 10 MB, and the file is sent only when you press the button — not while you browse.
  2. Pick a level. Low preserves image detail, Medium is the sensible default, and High pushes for the smallest possible file.
  3. Compress. The progress bar tracks the upload, then the server rebuilds the document. You can leave the tab open while it works.
  4. Compare and download. The result panel shows the original size, the new size and the percentage saved. Download the file if the reduction meets your limit.

Why use this tool

Email attachments, government portals and job boards often impose a hard size cap, and a scanned report can exceed it even though the content is simple. Compression that is too gentle leaves you over the limit; compression that is too aggressive turns readable text into a blur. Having three clear levels lets you make that trade deliberately rather than guessing at a quality slider.

The other half of the problem is trust. Documents sent for compression can contain payslips, contracts or medical records. The file here goes to a single conversion endpoint, is returned to your browser, and is removed from the server within 15 minutes — no account, no permanent library, no copy kept after the job.

Frequently asked questions

Is my PDF deleted after compression?
Yes. The uploaded file and the compressed result are removed from the server within 15 minutes. We do not keep a copy for reuse, training or any other purpose.
What do the three compression levels mean?
Low applies light recompression and keeps images close to their original quality. Medium is the default balance between size and appearance. High downscales images and objects more aggressively, so the file becomes smaller but photographs may look softer.
Why is my PDF only slightly smaller?
Some PDFs are already optimised, and pages that are stored as JPEG scans cannot be compressed much further without visible damage. Try the High level, or check whether the original file can be exported again with smaller images.
What is the upload limit?
One PDF up to 10 MB per conversion. If your file is larger, use the Split PDF tool to separate it into parts, compress each part, and merge the results if you still need one file.
What happens if the service is unavailable?
The page displays a temporary-unavailable message instead of an error code. Your file is not stored when the upload fails, so you can safely retry after a few minutes.
