Every PDF carries instructions for how it would like to be opened, and almost nothing lets you set them. A long manual is far easier to navigate when it opens with its bookmarks already showing. A scanned book reads properly as facing pages. A form is usable straight away when it opens fitted to the width instead of at some arbitrary zoom. These are one-line settings inside the file, and they change the first ten seconds of everyone’s experience with the document.
PDF is the universal document format: it locks layout, fonts and images so a file looks identical on every device and printer. Scans, invoices, forms, e-books and reports all travel as PDF. Because a PDF is a container rather than an image, turning its pages into JPG or PNG pictures — or bundling pictures into a PDF — are among the most common file tasks there are.
Every PDF carries a short set of instructions about how it would like to be opened: how the pages should be arranged, whether a side panel should be showing, what zoom to start at, and whether the window bar should show the document’s title or its filename. Almost every PDF leaves them unset, and almost no tool lets you change them.
They are worth setting because they decide what the reader meets before they have done anything. A 300-page manual that opens with its bookmarks panel already showing is navigable immediately; the same file without it looks like an undifferentiated wall of pages. A scanned book opened as facing pages reads like a book. A form that opens fitted to the width is usable straight away instead of at whatever zoom the reader last used on something else.
One long scroll is what most people expect from a modern reader and suits anything read start to finish. One page at a time suits slides and forms, where a page is a unit and half of the next one showing is a distraction. Facing pages suits anything that was designed as a spread — scanned books, magazines, brochures. Facing pages with a cover shifts the pairing by one, so the first page sits alone as a cover and every spread after it lines up the way the printed original did.
This one is an accessibility setting as much as a cosmetic one. Without it, viewers and screen readers announce the file by its name, so a carefully titled document still arrives as "invoice-2026-final-b". It only works if the document actually has a title — set one with Edit PDF Metadata first if it does not.
These settings are a request the file makes of whatever opens it. The major desktop readers honour them. Some browser viewers and mobile apps apply their own defaults instead, or respect some and ignore others. Nothing breaks when they do — the document simply opens the way that reader normally opens things — so it is worth setting for the readers that listen.
Yes — completely free, with no sign-up, no watermarks and no daily quota. Processing happens in this browser, so the practical limit is the memory available on your device.
Yes. Add as many files as you like — each one is processed in sequence with its own progress status, and you can download the results individually or all together as a ZIP archive.
No. Pages are copied at the object level — text, fonts, images and vector content are carried over as-is, without re-rendering. The output keeps the same sharpness and searchable text as the original.
The major desktop readers do. Some browsers and mobile viewers apply their own defaults instead, or honour some settings and not others — the request is stored in the file either way, so a reader that respects it will, and one that does not simply opens normally.
