Frequently Asked Questions
PDF to Word
How accurate is the PDF to Word conversion?
The accuracy depends on the type of PDF. Text-based PDFs with simple formatting convert with high accuracy. Complex layouts, scanned documents, or PDFs with special elements may have some formatting differences in the resulting Word document.
What format is the Word document saved in?
The converted document is saved in DOCX format, which is compatible with Microsoft Word 2007 and newer versions, as well as other word processors like Google Docs, LibreOffice, and OpenOffice.
Is my data safe when using this tool?
Yes, all processing happens directly in your browser. Your files are never uploaded to our servers, ensuring complete privacy and security of your documents.
Can this tool convert password-protected PDFs?
No, this tool cannot process password-protected or encrypted PDFs. You would need to remove the password protection before uploading the file for conversion.
Merge PDF
Is there a limit to how many PDFs I can merge?
Our tool allows you to merge up to 20 PDF files at once. If you need to combine more, you can merge them in batches.
Will the quality of my PDFs be affected after merging?
No, our PDF merger maintains the original quality of your documents during the merging process.
Can I merge password-protected PDF files?
Currently, our tool does not support merging password-protected PDF files. You'll need to remove the password protection before uploading.
Are my files stored on your server?
No, all processing happens in your browser. Your files never leave your device, ensuring complete privacy and security.
Compress PDF
Will compressing a PDF affect its quality?
Yes, compression can impact quality depending on the level chosen. Low compression maintains high quality with moderate size reduction, while high compression offers maximum size reduction but may affect image quality and text sharpness.
How much can I reduce my PDF file size?
The amount of reduction depends on the content of your PDF. Files with many images can often be reduced by 40-80%, while text-heavy documents may see a smaller reduction of 10-30%.
Is my data safe when using this tool?
Yes, all processing happens directly in your browser. Your files are never uploaded to our servers, ensuring complete privacy and security.
What types of PDFs can I compress?
You can compress any PDF file under 50MB. However, PDF files that are already heavily compressed or optimized may not see significant size reductions.
JPG to PDF
What image formats are supported?
Our tool supports JPG, JPEG, PNG, GIF, BMP, and WEBP image formats for conversion to PDF.
Can I control the quality of the PDF?
Yes, our tool preserves the original image quality in the generated PDF. For best results, use high-resolution images.
Is there a limit to how many images I can convert?
You can convert up to 20 images at once. If you need to convert more, you can do so in multiple batches.
Can I add text to my PDF?
Currently, this tool focuses on converting images to PDF without text editing. For adding text, you may need to use a PDF editor after conversion.
Split PDF
How can I select which pages to extract?
You can select specific pages using page numbers (e.g., 1, 3, 5-9), page ranges, or you can choose to extract all odd or even pages. Our interface makes it easy to specify exactly which pages you want.
Can I split my PDF into multiple separate files?
Yes, you can choose to split your PDF into separate files based on page ranges or split it into individual pages (one page per file).
Is the quality of the extracted pages maintained?
Yes, the Split PDF tool preserves the original quality, formatting, text, and images of your PDF when extracting pages.
Are there any page limits for splitting PDFs?
Our tool can handle PDFs with up to 500 pages. For extremely large documents, we recommend splitting them into smaller segments first.
Protect PDF
How secure is the password protection?
Our tool uses standard PDF encryption (AES-256) to protect your documents, which is considered highly secure. However, the strength of your password matters — we recommend using a strong, unique password with a mix of letters, numbers, and special characters.
What happens if I forget my password?
We cannot recover forgotten passwords as they are not stored anywhere. Make sure to remember your password or keep it in a secure password manager.
Can I set different types of permissions?
Yes, you can choose to restrict printing, editing, copying, and other activities while still allowing the document to be opened without a password, or you can require a password to open the document at all.
Is my data safe when using this tool?
Yes, all processing happens directly in your browser. Your files and passwords are never transmitted to our servers, ensuring complete privacy and security.
Reorder PDF
How does the reordering process work?
Our tool displays thumbnails of all pages in your PDF. You can simply drag and drop pages in the order you want them to appear in the final document. Once you're satisfied with the arrangement, click the "Reorder" button to generate your reordered PDF.
Can I also rotate pages while reordering?
Yes, our tool allows you to rotate individual pages 90°, 180°, or 270° while you're reordering them, which is useful for fixing scanned pages with incorrect orientation.
Is there a limit to how many pages I can reorder?
Our tool supports PDFs with up to 500 pages. For extremely large documents, the interface might become slower, so we recommend working with smaller segments.
Will bookmarks and links be preserved after reordering?
Internal links and bookmarks might be affected by reordering since they reference specific page positions. After reordering, these may point to different content. External links and other interactive elements should remain functional.
Watermark PDF
What types of watermarks can I add?
You can add text watermarks with customizable font, size, color, and opacity, or image watermarks using your own image files (PNG or JPEG recommended).
Can I control the position of the watermark?
Yes, you can position your watermark in any of 9 positions on the page (top-left, top-center, top-right, middle-left, center, middle-right, bottom-left, bottom-center, bottom-right) or as a diagonal overlay across the entire page.
Can I watermark specific pages only?
Yes, you can choose to apply the watermark to all pages, only the first page, only the last page, or specify custom page ranges where the watermark should appear.
Are watermarks permanent or can they be removed?
The watermarks applied with our tool become a permanent part of the PDF document. While specialized software might be able to remove them, they are designed to be permanent and not easily removable, making them suitable for copyright protection, drafts, or confidential documents.
