Frequently asked questions
How do I compress a PDF?
Drop your PDF into the box above, keep the Recommended compression level (or pick another), and press Compress PDF. Your smaller file is ready to download in seconds.
How much smaller will my PDF get?
It depends on the file. PDFs with lots of photos or scans often shrink a great deal; PDFs that are mostly text are usually already small and may not shrink much. You always see the original size, new size and reduction before downloading.
Will compression reduce quality?
Only images are recompressed. Text and vector graphics stay exactly as sharp as before. Basic keeps the highest image quality, Maximum gives the smallest file.
Is there a file-size limit?
You can compress PDFs up to 200 MB. Because everything runs in your browser, very large files need a device with enough free memory.
Are my PDFs secure?
Your files are processed in your browser and never uploaded to a server. Nobody else can see them.
Can I use it on my phone?
Yes. The tool works in modern mobile browsers — tap Choose PDF to pick a file from your phone.
