Image-based compression: pages are rendered as images, so selectable text, links, forms, bookmarks, accessibility tags and signatures may be lost. Use only with documents where a flattened copy is acceptable. No file is uploaded to NextWatch AI.

Frequently asked questions

How can I compress a PDF document online?

Select a PDF, choose a compression level and click Compress PDFs locally. Download only the result if the compressed file is smaller.

Will my PDF text stay selectable?

No. This method creates image-based pages, so text, links, form fields, signatures and accessibility information may be lost.

Can all PDFs be made smaller?

No. Some PDFs are already optimised. If the output is not smaller, the original file is retained and no misleading savings are reported.
