Frequently asked questions
How much smaller will my PDF be?
It depends on the content. Image-heavy and scanned PDFs shrink the most at Medium/High. MagicDocTool never returns a file larger than your original.
Will compression ruin my PDF quality?
Low uses lossless optimisation and keeps text crisp. Medium and High trade some image detail for a smaller size — you always see the exact result before downloading.
Is there a file size limit?
You can compress PDFs up to 200 MB per file.
