Frequently Asked Questions
Is my PDF safe? Do you store my files?
Absolutely safe! Your PDF never leaves your device. All compression happens directly in your browser using JavaScript. We don't upload your files to any server, and we have no access to your documents. When you close the browser tab, your files are completely gone. Your privacy is our top priority.
How much can I compress my PDF?
Most PDFs compress by 40-70%, though results vary depending on the file's content. PDFs with many images typically compress more than text-heavy documents. Files that are already optimized may see smaller reductions. Our tool uses smart compression algorithms to find the best balance between size reduction and quality.
Is there a file size limit?
No! Unlike many online tools, we don't impose file size limits. Compress files of any size, whether it's 1MB or 500MB. Since processing happens in your browser, the only limit is your device's capabilities.
Does compression affect PDF quality?
Our compression maintains readability and document integrity. Text remains crisp and clear. Images are optimized using advanced algorithms that preserve visual quality while reducing file size. For most business documents, presentations, and reports, you won't notice any quality difference.
Do I need to install software?
No installation needed! This is a completely web-based tool. Just visit our website, select your PDF, and compress. Works on any device with a modern browser - Windows, Mac, Linux, iPhone, iPad, or Android.
Can I compress multiple PDFs at once?
Currently, our tool processes one PDF at a time to ensure optimal performance and compression quality. Simply compress your first file, download it, and then process the next one. It's fast enough that handling multiple files individually is still quick and efficient.
Why compress PDFs?
Compressed PDFs are easier to email (most email providers limit attachments to 10-25MB), faster to upload and download, and take up less storage space on your device or cloud storage. They're also quicker to load when viewing on websites or sharing with colleagues.
Is this tool really free?
Yes, completely free! No hidden fees, no subscriptions, no credit card required. We may show ads to keep the service running, but the tool itself costs you nothing.
