Frequently asked questions
Is this PDF compressor free?
Yes, completely free with no usage limits.
How much will the file be reduced?
Lossless mode trims 5-30% on most PDFs. Balanced and Maximum rasterize each page as a JPEG and typically cut size by 50-80% — at the cost of selectable text.
Will compression affect quality?
Lossless keeps the file pixel-perfect (it only restructures the PDF). Balanced and Maximum rasterize pages at 144 or 96 DPI respectively — text turns into an image and becomes unsearchable.
Will my PDF be uploaded to a server?
No. Compression runs entirely in your browser.
Does it work offline?
Yes, after the first visit.
