Common Questions About PDF Compression

How much can I reduce my PDF file size?

Depending on the content (images vs. text-heavy pages), our tool can typically decrease PDF file size by anywhere from 40% to over 90%, especially for scanned documents or image-heavy files.

Will compressing my PDF reduce its quality?

Our compression engine is designed to strike a balance. When you choose the “high quality” setting, the visual difference is barely noticeable, even though the file becomes significantly smaller. If maximum size reduction is your priority, the “high compression” option will minimize PDF size more aggressively.

Is it safe to upload sensitive documents?

Yes. All files are transferred using secure encryption, and we do not retain copies of your documents after the compression process is complete.

Can I compress a password-protected PDF?

For security reasons, you’ll need to remove the password before compression, or use a version of the tool that supports protected files.

Do I need to install any software?

No. This is entirely an online pdf compressor, meaning everything happens in your browser — there’s nothing to download or install on your device.

Is there a limit to how many files I can compress?

No daily limits apply. You can use our free compress pdf online service as many times as you need.

Tips to Keep PDF File Sizes Small From the Start

While our tool makes it easy to compress a PDF file after the fact, here are a few habits that can help you avoid oversized files in the first place:

• Optimize images before inserting them into your document — resize photos to reasonable dimensions before adding them to a PDF.
• Avoid embedding unnecessary fonts — stick to standard fonts when possible.
• Scan documents at a reasonable resolution — scanning at 300 DPI is usually sufficient; higher resolutions dramatically increase file size.
• Remove unused pages or elements before exporting to PDF.
• Use our tool regularly as part of your workflow whenever you export or receive large PDFs.
