Documentation

Tips

• You can add as many files as your device's RAM allows.
• The output file order matches the order shown in the list.

Limitations

• Files must be valid, non-corrupted PDFs.
• Password-protected PDFs must be unlocked first.

Tips

• Use custom ranges (e.g., "1-3, 5, 7-10") for precise extraction.
• Splitting by every page is useful for creating individual slide PDFs.

Limitations

• Page ranges must be within the document's page count.

Tips

• PDFs that are mostly text won't shrink much — compression works best on image-heavy PDFs.
• Higher compression = smaller file but potentially lower image quality.

Limitations

• Output quality depends on the content of the original PDF.

Tips

• Works best on PDFs with minor structural damage or incomplete writes.

Limitations

• Severely corrupted files with missing data may not be recoverable.

Tips

• Upload exactly two PDFs for a meaningful comparison.

Limitations

• This tool provides visual review rather than semantic change tracking.

Tips

• Keep a copy of the original before deleting pages.

Limitations

• The original file remains unchanged on your device.

Tips

• Use page numbers to define a clear sequence.

Limitations

• Large files may take longer to render.

Tips

• PNG provides lossless quality, ideal for documents with text.
• JPEG produces smaller files, better for photo-heavy PDFs.

Limitations

• Very large or complex PDFs may take longer to render.

Tips

• Images are fitted to the selected page size while preserving aspect ratio.

Limitations

• Supported formats: PNG, JPEG, WEBP, GIF, BMP, TIFF.

Tips

• Best results with text-based PDFs. Scanned PDFs should use OCR first.

Limitations

• Complex formatting (multi-column, tables) may not convert perfectly.

Tips

• Preserves fonts, images, and basic layout.

Limitations

• Complex macros or embedded objects may not be preserved.

Tips

• Each PDF page becomes one slide.

Limitations

• Animations and transitions from original presentations cannot be recovered.

Tips

• Great for sharing presentations without requiring PowerPoint.

Limitations

• Animations are flattened to static slides in the output.

Tips

• Works best when the PDF contains clearly formatted, bordered tables.

Limitations

• Merged cells and complex table styles may not convert perfectly.

Tips

• Each worksheet becomes a separate page in the PDF.

Limitations

• Charts and graphs may not render identically to Excel's native print output.

Tips

• Inline your CSS for the most accurate output.
• External fonts and images may not load if they require an internet connection.

Limitations

• JavaScript is not executed during conversion.

Tips

• Higher-resolution scans produce more accurate results.
• Supported languages: English, French, German, Spanish, Arabic, Chinese, Japanese, and many more via Tesseract.js.

Limitations

• Handwritten text recognition is limited and may be inaccurate.
• OCR of complex layouts (multi-column, tables) may require manual cleanup.

Tips

• Use a consistent resolution across all scans for a uniform-looking document.

Limitations

• Image-only PDF — for searchable output, run OCR afterwards.

Tips

• JPG is useful for compact image sharing.

Limitations

• Image quality depends on the selected resolution.

Tips

• PNG is useful when crisp text and lossless quality matter.

Limitations

• Large PDFs can produce large image files.

Tips

• Use OCR first for scanned PDFs.

Limitations

• Complex layouts may change reading order.

Tips

• Use the editor for interactive page-level changes.

Limitations

• Some advanced editing capabilities are still being expanded.

Tips

• You can rotate individual pages independently.

Tips

• Use a low opacity (15–30%) for a subtle, professional-looking watermark.

Limitations

• Image watermarks should be PNG with a transparent background for best results.

Tips

• You can start numbering from any number to skip a cover page, for example.

Tips

• For a professional look, use the draw mode with a stylus or mouse.
• Uploaded signatures should be PNG images with a transparent background.

Limitations

• This is a visual signature, not a cryptographic digital signature. For legally binding eSignatures, use a dedicated eSign service.

Tips

• Cropping only adjusts the visible area — it does not permanently delete content outside the crop area in all viewers.

Limitations

• Page dimensions will change after cropping.

Tips

• Review every field before downloading.

Limitations

• Non-fillable PDFs may need the PDF Editor workflow.

Tips

• Text-based PDFs produce the cleanest results.
• Scanned documents should go through OCR first.

Limitations

• Complex layouts, tables, and scanned pages may need manual cleanup.

Tips

• Ask for key points, decisions, risks, or action items.
• Verify names, numbers, and dates before relying on the result.

Limitations

• Scanned PDFs need OCR and important claims require human review.

Tips

• Keep a terminology list for technical documents.
• Check right-to-left scripts, dates, names, and units carefully.

Limitations

• Exact layout preservation is not guaranteed and regulated content needs qualified review.

Tips

• Use a strong, unique password. SelfPDF has no way to recover it if lost.
• AES-256 encryption is used for maximum security.

Limitations

• You are responsible for remembering your password. SelfPDF cannot recover it.

Tips

• Only use this tool on PDFs you own or have explicit permission to unlock.

Limitations

• Requires the correct password — SelfPDF does not perform brute-force cracking.

Tips

• Always inspect the exported document before sharing.

Limitations

• Redaction quality depends on the selected content and PDF structure.
