Frequently Asked Questions
Find answers to common questions about this tool
How can I reduce PDF file size online?
Select a PDF up to 100 MB, run compression, and download the smaller file. Processing happens in your browser.
Will compressing a PDF affect readability?
Text and images keep their original resolution. This tool removes redundant structure and metadata rather than downsampling images, so savings vary and some files barely change.
Is this PDF compressor good for scanned files?
It can remove unneeded objects, but it does not recompress the scanned images. For image-heavy scans, compress the images first and then rebuild the PDF.
Can I compress a PDF for email attachments?
Yes, but there is no guaranteed size reduction. If the result is still too large, split the PDF and send only the needed pages.
Why is my PDF the same size after compression?
The file may already be optimized, or most of its size may come from embedded images that this tool leaves untouched.
Is this PDF compressor free?
Yes. There is no signup, watermark, or daily quota; the limits are one PDF at a time and 100 MB.
