Frequently asked questions

What does Merge PDF do?

Combine several PDF files into one.

When would I actually use this?

Getting a document into the shape someone asked for: merging attachments into one file, pulling out the pages that matter, rotating a bad scan, or signing before sending back.

What is the most common mistake?

Drawing a black box over text to redact it. The characters are still in the file underneath and can be selected and copied — removing them means deleting the content, not covering it.

How is Merge PDF different from Compress PDF?

They sit next to each other but answer different questions: Compress PDF is the one to open when you need it to shrink a PDF without losing anything: identical fonts and images repeated by a merge are merged back into one. A whole folder at once. Pick whichever matches what you're starting from — both are free.

Is there a tool for the next step?

Crop a PDF is the closest one after this: Drag a frame on the page to set the crop, or let the white margins be detected. Several documents at once, to the same measurements.

What else is worth having open alongside it?

Delete PDF pages and Extract links from a PDF — they come up in the same task often enough to be worth a second tab.

Where do the figures come from?

The working copy lives only as long as the tab does: nothing is kept between visits, and nothing can be recovered once you close it. Save the output before you leave, and keep the original until you have checked the result.

How-toMerging an Application Pack into One PDF, in the Right OrderA rental file, a loan application, a tender: the requester wants one document, in the order they listed. The merge itself takes seconds. What goes wrong is the ordering, the page sizes and the file that silently loses its signature — all of which are avoidable if you know where they bite.How-toPhotographing a Document and Getting a PDF That Is AcceptedNobody owns a scanner any more, so the phone does it. Two things decide whether the result is accepted: how you took the photograph, and what page size it becomes. The second one surprises people, because a photograph turned into a PDF is not A4 unless something makes it A4.How-toAdding Page Numbers to a PDF When the Pages Are Rotated or Mixed SizesNumbering a tidy document is trivial. The cases that bite are a page turned sideways, a Letter sheet among A4 ones, a print file with bleed, and a document that already prints its own number. All four were tested: on the first three the number lands exactly where you asked, and the fourth is not detected at all.GuideWhat a PDF Says About You: Reading and Clearing Its MetadataA PDF carries its metadata twice, in two stores that can tell different stories, and neither of them is the whole story. Here is what is actually in the file, what clearing it removes, and the two things that survive every wipe.How-toTurning Notes into a PDF Worth ArchivingPlain text has no layout, so any converter has to invent one for you. Here is exactly which decisions this one makes — page, margins, font, line breaks — what it does with a tab and a long line, and what you have to add yourself before a note is worth keeping.ExplainerYour PDF Looks Straight to You and Sideways to ThemYou rotated the scan, saved it, and the recipient still opened it sideways. Nothing is broken — rotation in a PDF is an instruction rather than a change to the page, and instructions can be ignored. Here is when that happens and how to produce a file that cannot be misread.
