Frequently Asked Questions
Is this PDF compressor safe to use?
Yes, completely safe. Everything runs inside your browser using JavaScript. Your PDF is never uploaded to any server. Your file stays on your device at all times — 100% private.
Is it completely free?
Yes — no signup, no credit card, no hidden charges, no usage limits. FileCraftyHub PDF Compressor is always free.
How much can I reduce a PDF's file size?
You can reduce PDF size by up to 90% depending on the content. PDFs with many images compress the most. Text-only PDFs compress less. Use the quality slider to find the right balance.
Will compression affect my PDF quality?
At 60–80% quality, the visual difference is minimal and unnoticeable in most cases. At lower values (below 40%), you get a much smaller file with some visible quality reduction. You control this entirely with the slider.
Can I compress a PDF on my phone?
Yes! The tool is fully mobile-responsive and works on Android and iOS browsers like Chrome, Safari, and Firefox — no app required.
Is there a file size limit?
There's no strict limit from our side. However, very large PDFs (above 100 MB) may take longer to process depending on your device's CPU and RAM.
What types of PDFs compress the best?
PDFs containing images, scanned documents, and photos compress the most — often achieving 60–90% size reduction. Text-heavy PDFs with no images compress less, typically 10–30%.
Do I need to create an account?
Absolutely not. No account, no login, no email required. Just open the page and start compressing immediately.
