PDF guides and step-by-step instructions

Practical walkthroughs: how to compress and merge PDFs, convert them to Word and Excel, sign a document and stamp it. Free, and everything runs in your browser.

Every guide here is written against the tools on this site, so the steps match what you will actually see on screen — including the places where a browser-based tool cannot do what a desktop program does. Where that is the case, it says so.

Most of these started as questions people arrive with: a portal that rejects anything over 100 KB, a merged document whose pages came out in the wrong order, a Word file that lost its columns, a signature that may or may not be accepted. Each guide answers one of those and links straight to the tool that finishes the job.

Nothing you open here is uploaded anywhere. Every tool on the site runs inside your own browser, which is why contracts, statements and ID scans are safe to work on — they never leave your device, and closing the tab leaves no copy behind.

How to compress a PDF to 100 KBA portal wants your PDF under 100 KB. What actually gets you there, what the arithmetic will not allow, and what to do when compressing alone is not enough. How to merge PDF files in the right orderMerged PDFs come out shuffled for one boring reason: computers sort scan1, scan10, scan2. How to get the sequence right and check it before you download. PDF to Word without losing formatting: what really survivesWhat actually survives a PDF to Word conversion, what no converter can restore, and the five-second test that tells you whether your file will convert at all. How to scan documents with your phonePhotograph paperwork so it is actually accepted: light, background, page order, why iPhone HEIC files will not open, and how to turn the shots into one PDF. How to sign a PDF documentDrawing a signature on a PDF takes a minute. Knowing when that is accepted and when you need a certificate-based signature is the part worth reading first. How to extract pages from a PDFExtracting, splitting and deleting are three different jobs with three different results. Pick the right one, then pull out exactly the pages you need. Why is my PDF so large?A 20-page contract weighs less than a single phone photo. Here is where the megabytes in your PDF actually come from and which fix works for your kind of file. How to add page numbers to a PDFNumber a PDF the way a thesis committee, a court clerk or a tender panel expects — including what to do about the title page and why you should number last.
