Good to know
This tool shrinks a PDF by turning each page into a compressed image. It works very well for scanned documents and photo-heavy files. Because pages become images, the text in the new file cannot be selected or searched, so keep your original for editing. If the result would not be smaller, the file is already optimised.
Frequently asked questions
Will the quality drop?
Slightly. Recommended keeps pages clear on screen and in print. Use Light for the best quality or Strong for the smallest size.
Why can I not select text after compressing?
Pages are saved as images to reduce size. Keep the original PDF if you need searchable text.
Is my file uploaded?
No. Compression happens in your browser.
