Questions and practical tips
Which compression mode should I choose?
Try structural optimization first when preserving the document structure matters. Image-based compression renders pages as images and can reduce scanned or image-heavy documents more strongly.
Can stronger compression affect searchable text?
Yes. Image-based compression can remove text selection, searchability and interactive features. Keep the original and test the exported PDF before replacing it.
Processing and file safety
This tool processes files in your browser. Loading the page, libraries or AI models can still require network connections. Keep a copy of your original files and check the downloaded result before deleting them. Large files may require more memory and processing time than your device can provide.
