FAQ
How much can the file size be reduced?
Reduction depends on the content. Image-heavy PDFs can be reduced by 50-80%. Text-only PDFs may see smaller gains since text is already compact.
Does compression reduce quality?
Low compression preserves near-original quality. Medium offers a good balance. High compression produces the smallest file with some visible quality reduction in images.
Is the text still selectable after compression?
Compressed PDFs use rendered page images, so text becomes part of the image. For text-heavy documents, use Low compression for the best results.
Is there a file size limit?
No hard limit. Large files may take longer to process depending on your device. Most PDFs under 50 MB compress in seconds.
Is my PDF uploaded to a server?
No. All compression happens locally in your browser. Your files never leave your device.
