Compress PDF
Reduce PDF file size with control over quality.
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.
