FAQs:
Is this Compress PDF tool free? Yes, it is completely free with no limits and no signup.
Are my PDF files uploaded anywhere? No. Compression happens inside your browser, so your files never leave your device.
Will I lose text or quality after compressing? With Basic, nothing changes. With Recommended and Strong, each page is converted to an image, so image quality is reduced and text can no longer be selected or searched.
Which level should I choose? Use Basic if you need to keep selectable text. Use Recommended for most files, and Strong when you need the smallest size possible.
Why did my PDF not get smaller? Some PDFs are already well optimized, so the result would not be smaller. In that case the tool tells you and your original file stays unchanged.
Can I compress a password-protected PDF? Not directly. Remove the password first, then upload the file.
