Why turn PNGs into a PDF at all
A folder of screenshots is awkward to send and worse to read: every receiver opens ten attachments in ten tabs, in whatever order their mail client chose. The same ten images as one PDF read like a document — ordered, paged, printable, and viewable on any device without an image gallery. That is why forms, applications and expense systems so often demand "one PDF" rather than loose images.
PDF also fixes the layout. A PNG has no notion of paper: printed directly, it lands wherever the printer driver decides. Placed on an A4 or Letter page with a margin you chose, it prints the same way everywhere — which is the whole point of the format.
Page size, orientation and order — the three choices that matter
Pick A4 or Letter when the PDF is headed for a printer or a form upload; pick "same as image" when the images are the document — screenshots, artwork, scanned pages — and cropping or letterboxing them onto paper shapes would only shrink them. Orientation follows the content: portrait for phone screenshots and documents, landscape for desktop captures and photos.
Order is set by dragging the thumbnails before converting, and it is worth the ten seconds: page order is the one thing you cannot fix after the PDF exists without another tool. Each image becomes exactly one page, embedded without re-compression, so every pixel of the original PNG — transparency flattened onto white, as PDF requires — survives into the document.
The margin slider is the quiet workhorse of the three. At zero the image bleeds to the paper's edge, which looks right for full-page artwork but gets clipped by most physical printers. Ten millimetres — the default — keeps everything inside the printable area of every common printer, and gives screenshots the breathing room that makes a stack of them readable as a document rather than a contact sheet.
- One PDF for a job application → A4, portrait, 10 mm margin
- Screenshots for a bug report → same as image, no margin
- Photos to print at home → A4 or Letter, orientation to match the photos
Private by construction
Every step runs inside your browser, using the WebAssembly and Canvas APIs your device already ships with. No file is uploaded, no copy is kept, and nothing sits in a queue on a server waiting to be deleted — which is also why the tool keeps working with the network disconnected.
Screenshots are the most common input here, and screenshots are the least filtered documents anyone owns — they show whatever was on screen, chat names and account numbers included. Building the PDF locally means none of that ever crosses the network.
It also means there is no file-count meter and no daily limit to run into: the only resources being spent are your own device's. Convert one screenshot or two hundred batches of them — the tool neither knows nor cares, because there is no account and no server keeping score.
Frequently Asked Questions
Can I put several PNGs into one PDF?
Yes. Add up to 20 images and drag them into the order you want — each one becomes a page of the same PDF.
Does converting PNG to PDF lose quality?
No. The images are embedded in the PDF without re-compression, so every pixel of the original PNG is preserved.
Are my images uploaded anywhere?
No. The PDF is built entirely in your browser and your images never leave your device.
