Everything here is grouped by the situation you are in, not by tool name. Each guide explains why it happens first, then gives steps you can follow directly — and the tool that does the work sits at the top of the page.
Nobody searches for "merge tool". They search for "two photos on one page" or "my PDF is still too big after compressing", because that is the situation they are stuck in. So every guide here is titled after the problem rather than the feature, and the tool that solves it sits at the top of that page instead of on a separate menu.
A step list gets you through today and leaves you stuck again next month. The guides start with why the problem exists — why a text PDF barely compresses while a scan shrinks tenfold, why Word stores font names instead of fonts, why a phone photo never turns white by itself — so the next time you meet the same problem you already know which lever to pull.
Merge, split, compress, encrypt, PDF to image and image to PDF run entirely in your browser, so the file never reaches a server. PDF to Word and Word to PDF are different: they need LibreOffice, so the file is uploaded to this site's own server, converted, and deleted right after. That distinction is stated on each tool page rather than buried in a policy.
When the same question keeps coming up, it gets its own guide. The list grows by real situations, not by keyword volume.
No. No account, no watermark, no page limit on the tools that run locally.
Only PDF to Word and Word to PDF. Everything else runs in the browser and the file stays on your device.
Pick the closest guide — most of them share the same root cause, and each one links to the tools that do the work.
