## Guides

- [Why a compressed PDF loses selectable text](https://pctoolsonline.com/guides/why-compressed-pdfs-lose-text.html): This compressor redraws each PDF page as a JPEG. Scans get smaller. Real text often gets larger, and it is no longer selectable. Limit 40 pages. Markdown: https://pctoolsonline.com/guides/why-compressed-pdfs-lose-text.md
- [What PDF to Word actually copies](https://pctoolsonline.com/guides/what-pdf-to-word-actually-copies.html): PDF to Word copies the real text layer into a DOCX, one line per paragraph. It does not rebuild columns, tables, headers, or the page design. Limit 80 pages. Markdown: https://pctoolsonline.com/guides/what-pdf-to-word-actually-copies.md
- [PDF to Excel is a spacing guess](https://pctoolsonline.com/guides/pdf-to-excel-is-a-spacing-guess.html): PDF to Excel guesses columns from gaps in the text layer and downloads XLSX or CSV. It does not rebuild merged cells, ruled tables, or formulas. Scans come out empty. Limit 80 pages. Markdown: https://pctoolsonline.com/guides/pdf-to-excel-is-a-spacing-guess.md
- [What Word to PDF keeps and drops](https://pctoolsonline.com/guides/word-to-pdf-limits.html): Word to PDF turns DOCX paragraphs into a plain US Letter PDF. Bold and italic stay. Tables, images, headers, and CJK text do not. Old .doc files are refused. Limit 80 pages. Markdown: https://pctoolsonline.com/guides/word-to-pdf-limits.md
- [What HEIC to JPG keeps and drops](https://pctoolsonline.com/guides/heic-to-jpg-what-you-lose.html): HEIC to JPG converts iPhone HEIC or HEIF photos at a fixed JPEG quality of 0.92. Each file downloads on its own. Live Photo bursts keep the first frame only. EXIF is not promised. Markdown: https://pctoolsonline.com/guides/heic-to-jpg-what-you-lose.md
- [The image quality slider is not a file-size percent](https://pctoolsonline.com/guides/image-quality-slider-is-not-file-size.html): The image compressor redraws one image as a JPEG at the same pixel size. The slider, from 0.1 to 1, is JPEG quality, not a percent of the file size. Transparency is lost. The download is always compressed.jpg. Markdown: https://pctoolsonline.com/guides/image-quality-slider-is-not-file-size.md
- [What the mortgage calculator leaves out](https://pctoolsonline.com/guides/mortgage-calculator-principal-and-interest.html): The mortgage calculator estimates fixed-rate principal and interest only. Taxes, insurance, PMI, points, and today's rate are not included. The default example is $1,769.79 a month on a $280,000 loan. Markdown: https://pctoolsonline.com/guides/mortgage-calculator-principal-and-interest.md
- [Merge, split, or reorganize a PDF](https://pctoolsonline.com/guides/merge-split-or-reorganize-a-pdf.html): Merge joins PDFs in the order you add them. Split extracts a page range or saves every page. Organize reorders, rotates, or deletes pages. All three copy pages, so real text stays selectable. Markdown: https://pctoolsonline.com/guides/merge-split-or-reorganize-a-pdf.md
- [When English OCR on a PDF works](https://pctoolsonline.com/guides/when-english-ocr-on-a-pdf-works.html): English OCR on PDF to Word uses Tesseract in the browser for pages that are pictures of printed English. It misses small type, handwriting, and other languages. It does not run from a file opened as file://. Markdown: https://pctoolsonline.com/guides/when-english-ocr-on-a-pdf-works.md
- [What the browser does with your file](https://pctoolsonline.com/guides/what-the-browser-does-with-your-file.html): PDF and image tools read the file you pick inside the tab. They do not store it on this site. The page itself still loads libraries from a CDN, so opening a tool needs a network connection. Markdown: https://pctoolsonline.com/guides/what-the-browser-does-with-your-file.md
