FAQs
Frequently asked questions about PDF compression
How do I compress a PDF online for free?
Choose a PDF, wait for the first compressed preview, then move the quality slider until the file size and image quality suit your needs. Download the current version when you are happy with it.
Can I see the compressed PDF size before downloading?
Yes. The tool generates a real compressed preview and shows the actual output size and percentage saved before you download it.
Can I compress a PDF to 1 MB or 2 MB?
You can move the slider toward a smaller file and watch the generated size update. The exact size depends on the PDF, so a specific target such as 1 MB or 2 MB cannot be guaranteed for every document.
Will PDF compression reduce quality?
Compression mainly reduces embedded image resolution and JPEG quality. Text and vector content usually stay sharp. Move the slider toward Better quality when image clarity matters more.
What quality setting should I use?
The default 60% Balanced setting is a practical starting point for most documents. Move left for a smaller file or right for clearer images.
Why did my PDF not become much smaller?
Some PDFs are already optimized, mostly contain text or vector graphics, or use compressed images. Those files may have less removable data without visible quality loss.
Does this work well for scanned PDFs?
Often yes. Scanned PDFs commonly contain large page images, so reducing image resolution can save significant space. Stronger compression can make small text in scans less clear, so check the quality you need.
Can I use the compressed PDF for email, job portals and online forms?
Yes. The compressor is useful for reducing PDFs before email attachments, job applications, government or school forms, websites and other services that impose upload limits.
What is the maximum PDF upload size?
The current upload limit is 50 MB per PDF.
Are my PDF files stored permanently?
No. The compressor uses temporary server files. Its cleanup routine removes temporary files after they are older than 30 minutes during tool activity.
Can I compress a password-protected or damaged PDF?
Protected, encrypted, damaged or unsupported PDFs may fail to compress. If that happens, try an unlocked valid PDF.
Can I use the PDF compressor on a phone or tablet?
Yes. The tool runs in a modern web browser and its interface is designed to work on desktop, tablet and mobile screens.
