Short, honest walkthroughs for the things people actually come here to do — including what each tool cannot do, so you are not left guessing.
- How to summarize a PDF with AIA useful summary should shorten the reading without pretending to replace it. This tool reads the PDF text on your device, sends only a bounded text extract to an AI service, and gives you control over the length, emphasis and output language.
- How to scan documents to PDFYou do not need a flatbed scanner to turn paper into a clean PDF. A phone camera is enough if the page is well lit and held flat. This scanner finds the document edges, straightens the perspective and combines every page into one PDF — entirely on your device, without uploading the photos.
- How to compress a PDFMost PDFs get rejected by email and government upload forms for one reason: the file is too big. Compressing rewrites the file so it carries less overhead. It takes a few seconds and, here, it happens on your own device — the PDF is never sent anywhere.
- How to merge PDF files into oneRequirements get submitted as one file more often than not — an application, a liquidation, a set of receipts. Merging joins your PDFs end to end in whatever order you choose, and here it happens entirely on your device.
- How to edit a PDFEditing a PDF usually means one of two things: fixing text that is already in the document, or adding something on top of it — a name, a date, a signature. This editor does both, and your file never leaves the device.
- How to split a PDFAlmost every form that asks for a PDF wants a few specific pages, not the forty-page document those pages came in. Splitting takes the pages you name and writes them out as their own file. It runs on your own device — the PDF is never sent anywhere.
- How to convert a PDF to images (and images to PDF)Sometimes the thing that will accept your document is not a document field at all: a chat box, a Facebook post, an upload that only takes JPG. And sometimes it is the reverse — you have five photos of a form and what is wanted is one PDF. These are two separate tools, PDF to Image and Images to PDF, and both run here on your own device, with nothing uploaded.
- How to convert a Word document to PDFAlmost every online application, scholarship form and job posting asks for a PDF, and what you have is a .docx. Converting it here happens on your own device: the document is read in your browser and written back out as a PDF with real, selectable text. Nothing is uploaded, which matters when the document is a resume, a medical record or a signed letter.
- How to convert a PDF to WordSomebody sent you a PDF and the thing you need to do with it is change it. A PDF is not built for that: it stores letters at fixed positions on a page, with no idea which of them are a paragraph. Converting to Word reconstructs that — the paragraphs, the headings, the lists — so you get a document you can actually type in. It runs on your own device, and the file is not uploaded.
- How to rotate a PDFA scanner fed a page the wrong way round, and now half your document is sideways. Rotating here writes the turn into the file itself, so it stays turned for whoever opens it next — and it does it without touching a single thing your pages contain.
- How to add a watermark to a PDFA watermark says what a copy is for. Marking an ID copy with the transaction it was submitted for, a draft as a draft, or a quote as not yet final is the most useful thing you can do to a document you are about to hand over. It takes a minute here and, as with everything on this site, the file never leaves your device.
- How to lock or unlock a PDFLocking writes a real password into a PDF, using the same AES-256 encryption every current reader already supports. Unlocking runs the same thing backwards: given the password a file already has, it writes out the same document without it. Both happen in your browser tab — the file is never sent anywhere.
- How to turn images into one PDFA folder of photographed forms or receipts is awkward to submit and easy to put in the wrong order. Images to PDF places each picture on a page, lets you arrange and rotate everything first, and creates one file entirely in your browser. It is useful for photographed paperwork, signed forms, class notes and any upload that asks for one PDF instead of several images.
- How to crop PDF pagesCropping changes the part of a PDF page that readers and printers show. It is useful for removing scanner-bed borders, oversized white margins, headers you do not need, or empty space around an exported drawing. PDF Tool PH changes the page boundary instead of turning the page into a screenshot, so text and line art stay sharp.
- How to redact private information from a PDFDrawing a black rectangle in an editor often hides information visually while leaving the original text available to copy, search or uncover. Proper redaction removes the underlying content before adding the visible box. Use it before sharing payslips, bank statements, identification, medical forms or contracts with someone who does not need every detail.
