Compress PDF Online — Reduce PDF File Size
Choose the right settings
Start with lossless compression to preserve document content. For image-based output, choose the raster mode and the image quality you need.
Save and review
Select Compress PDF, download the result and check it before sharing. Keep your original files.
Why did my PDF not get smaller?
Already optimized files may not shrink. Lossless mode retains the original when its result is larger. Image-based compression can remove selectable text, links and form fields.
