How to use Compress PDF
Upload a PDF, choose output image quality and render scale, then create a new PDF from the rendered pages. Compare the source and output file sizes before downloading.
Supported workflow and limitations
This compression method rasterizes pages. It can remove selectable text, links, forms, accessibility tags and vector sharpness. It is unsuitable when searchable text or exact document structure must be preserved.
Privacy and file handling
Your selected files are processed in your browser. ProTools does not require you to upload them to a document-processing server. Required JavaScript libraries and language data may be downloaded from their respective CDNs. Analytics and advertising are controlled separately by your cookie preferences.
Frequently asked questions
Will the compressed PDF remain searchable?
No. This method rebuilds pages as images, so selectable text is not retained. Use it only when a visual PDF is acceptable.
Why can a PDF become larger?
If the source already contains optimized images or vector content, rasterizing at a high scale may increase file size.
Does compression happen locally?
Yes. PDF rendering and rebuilding are performed in the browser.
