FAQ
Compress PDF — frequently asked questions
How much can I reduce my PDF's size?
It depends on what is inside. PDFs full of photos and scans shrink a lot, while text-only PDFs are already small. Pick a quality profile or set a target size and the tool shows the result size.
Will the text stay sharp after compression?
Yes. The compressor reduces the resolution of images but keeps text and vector graphics intact, so words stay crisp and selectable.
Can I compress several PDFs at once?
Yes, up to five files in one go, and you can download each compressed file separately.
Is my file uploaded? Is Compress PDF safe to use?
Compress PDF needs our processor to do the conversion, so your file travels over an encrypted HTTPS connection to a private temporary folder. It is deleted automatically when the download finishes or you leave the page, and we never read, keep or share it.
Is Compress PDF free? Is there a file size limit?
Yes, it is free with no account, signup or watermark. Very large files can be rejected or take longer, so split or compress them first if the upload does not go through.
