Compress PDF
Rebuilds each page as a compressed image at your chosen quality — a good fit for image-heavy PDFs. Selectable text will become part of the image, so it won't be selectable afterward.

About the Compress PDF
The PDF Compressor reduces a PDF's file size with an adjustable quality slider. It is useful when an email, job portal or form limits attachment size. After compression the tool shows the original size, the new size and the percentage saved.
It works by drawing every page and re-saving it as a compressed JPEG image inside a new PDF. This can shrink PDFs that are mostly photographs or scans considerably, but it has a trade-off you should know: the text on the pages becomes part of the picture, so it is no longer selectable or searchable, and links are lost. A PDF that is already mostly text and vector graphics may even become larger. If the result is larger than the original, keep the original or try a lower quality setting.
How to use it
- Upload the PDF.
- Move the Quality slider; lower values give smaller files and softer images.
- Press Compress & download.
- Compare the sizes shown and check the result visually.
Tips and good to know
- Try a middle quality first and lower it only if needed.
- Keep the original file; compression cannot be undone.
- For text documents, reduce the size at the source (for example by exporting from the original document with image compression).
Frequently asked questions
Why is the text no longer selectable?
Each page is saved as an image.
Why did my file get bigger?

No.
