Frequently Asked Questions

How to reduce PDF size for a job application?
Just upload your resume or portfolio PDF. We will optimize the embedded images and fonts to ensure the file size drops below common portal limits (like 2MB or 5MB).
Will my scanned signature still be readable?
Yes. While we aggressively compress the image to save space, we ensure the resolution stays high enough for signatures and text to remain perfectly crisp on screen.
Does this tool add a watermark to my PDF?
Never. Unlike other free tools, we don't stamp our logo on your important documents. It's 100% clean.
Can I compress a PDF directly on my phone?
Yes, our website is fully optimized for mobile. Simply tap 'Upload', select the PDF from your files, and download the compressed version instantly.
