Compress PDF Online — Free
Choose a compression level and compare file size. This tool rebuilds each page as an image, which can reduce text searchability and visual detail.
The compressor renders each PDF page to a JPEG image and builds a new PDF from those images. This can reduce file size, but it also rasterizes text and vector content, so text may no longer be selectable or searchable and fine detail can be lost. Compression results depend on the source file and selected settings. Processing runs in your browser; review the downloaded file before sharing or submitting it.

Frequently Asked Questions
How much smaller will the PDF be?
There is no guaranteed reduction. Results depend on the source PDF and compression setting; compare the output size and appearance before using the file.
Will text remain selectable after compression?
This tool rebuilds pages from rendered images, so text and vector elements become raster images and may no longer be selectable or searchable.
Can I compress a password-protected PDF?
Not directly. First use our Unlock PDF tool to remove the password, then compress the unlocked version.
Where is my file processed?
The compressor processes the selected PDF in your browser. Avoid using any online tool for sensitive documents unless its privacy practices meet your needs.
