If you only need a few pages from a large document, use the "Page Range Selection" to dramatically reduce the file size.
Remove Unneeded Data
For maximum privacy and a slightly smaller file, enable the 'Remove Metadata' option to strip hidden author and creation data.

Best Free Compressor Out There
I've tried other online tools, but they were slow or full of ads. This one is clean, fast, and the page selection feature is a great way to shrink big files. Highly recommend.

Perfect for Extracting Pages!
I had a 200-page manual but only needed to send 5 pages to a client. The page selection tool worked flawlessly and created a tiny PDF. So much easier than splitting the file first.

Made My Scanned Documents Usable
Scanned documents are always huge. This tool compressed my scanned invoices by over 80% with the 'High' setting. The text is still perfectly readable. It's now my go-to for archiving.

Frequently Asked Questions
Get instant answers to common questions about our PDF Compression tool.
Is it safe to upload my documents to compress them?
Yes, it is 100% safe. Your privacy is our top priority. The entire compression process happens locally in your browser. Your files are never uploaded to our servers, ensuring your data remains completely private.
Why can't I select text in the compressed PDF?
To achieve the highest possible compression, our tool converts each page of your PDF into a high-quality JPEG image. The final document is then built from these images. Because the pages are now images, the original text data is not retained, making it non-selectable and non-searchable. This method is best for sharing, viewing, or archiving, but not for documents where you need to copy text.
Will compressing reduce the quality of my PDF?
Yes. Because pages are converted to images, there will be a reduction in quality, especially for sharp text or vector graphics. The 'Compression Level' you choose directly controls this balance. 'Basic' offers the best quality with moderate compression, while 'Extreme' provides the smallest file size at the cost of visual clarity.
How much will my file size be reduced?
The reduction can be significant, often over 70-90%, especially for documents heavy with text and vector graphics. The final size depends almost entirely on the 'Compression Level' you select. Selecting a specific range of pages from a large document will also dramatically reduce its size.
What do the compression levels do?
The compression levels directly control the quality of the JPEG images that your pages are converted into.
Basic: High image quality, larger file size.
Recommended: A good balance between quality and file size for most uses.
High: Noticeable quality reduction, but a much smaller file.
Extreme: Lowest image quality for the absolute smallest file size, best for when size is more important than clarity.
What happens to my file after I'm done?
Since your file is never uploaded, it remains on your computer. The compressed PDF is generated in your browser, and you download a new copy. We never see, access, or store your original or compressed files.
