A lighter PDF, kept local.
Rebuild scanned or image-heavy pages in your browser. Output pages are images; text selection, search, links, and forms are not preserved.
Add PDF files
Drop one PDF or a small batch into the workbench. Files stay in the browser and are not uploaded.
Choose compression mode
Small favors smaller output, Balanced is the default, and Sharp keeps more visual detail.
Download compressed PDFs
The browser renders pages, rebuilds a new PDF, and lets you download the compressed result.
PDF compressor FAQ
Key details about browser-based PDF compression.
Are my PDFs uploaded?
No. PDF processing runs in your browser and does not upload files to PixLoading servers.
Does this use credits?
No. PDF Compressor is a free utility and does not create AI tasks or use credits.
Why can some PDFs become larger?
This tool rebuilds pages from rendered images. It works best for scanned or image-heavy PDFs. Vector-heavy text PDFs may not shrink.
Can it process encrypted PDFs?
Encrypted or restricted PDFs may fail if the browser cannot render the pages.
Will text remain searchable and selectable?
No. Pages are rebuilt as images, so searchable/selectable text, links, forms, and other interactive content are not preserved. Keep the original PDF if you need those features.
