Frequently Asked Questions
How much can I compress a PDF?expand_more
It depends on the content. Image-heavy PDFs often shrink by 50 to 80 percent. Text-only files are already compact and see smaller reductions.
Does compressing a PDF reduce quality?expand_more
You choose the compression level. Light compression is nearly lossless, while aggressive compression trades some image quality for much smaller files.
Is my PDF uploaded to a server for compression?expand_more
No. PDFLocal compresses your file entirely in your browser. Nothing is ever uploaded.
Can I compress a PDF that is already compressed?expand_more
You can try, but results vary. If the file was already well-optimized, further compression may be minimal.
