How to use PDF Tools
Frequently Asked Questions
What is the maximum PDF file size that can be processed?
There is no hard server-side limit since processing happens in your browser, but file size is limited by your device's available memory. Most modern devices handle PDFs up to 50–100MB without issues. Very large PDFs with hundreds of high-resolution scanned pages may cause slow processing or browser memory warnings on older devices.
How much does compressing a PDF reduce its file size?
It depends heavily on the content. PDFs that consist mostly of text with minimal images compress very little — text is already efficiently stored. PDFs with high-resolution embedded photos, scanned documents, or graphics can be compressed 50–80%. A 15MB scanned report can often be reduced to 2–4MB at medium quality with no visible degradation in text readability.
Can I merge password-protected PDFs?
No, password-protected PDFs cannot be merged or processed without first unlocking them. If you know the password, open the PDF in a PDF reader, remove the password protection, save it, and then use that unlocked file in the merge tool. The tool does not have password-cracking functionality.
Does converting PDF to JPG preserve the text quality?
PDF to JPG conversion rasterizes the page at your chosen DPI. For text, 150 DPI produces readable quality for screen use and standard printing. For text that needs to remain sharp for OCR processing or high-resolution printing, use 300 DPI. Higher DPI produces larger file sizes — choose based on your intended use.
Are my PDF files uploaded to a server?
No. All PDF operations run entirely in your browser using JavaScript libraries. Your files are never sent to any server — they are read from your local disk, processed in your browser's memory, and the output is downloaded directly to your device. This makes the tool suitable for processing confidential documents like legal contracts, financial reports, and medical records.
