VUISO IMAGE TO PDF — how to use =============================== Turn pictures into one PDF: photos of a receipt, a set of scans, screenshots for a report. Everything happens inside your browser. Nothing is uploaded, there is no account, and it works with the network switched off. One picture becomes one page, in the order you arrange them. OPENING IT Double-click "Vuiso Image to PDF.html". It opens in your browser like a normal page. There is nothing to install. Chrome or Edge is recommended; Firefox and Safari work too. THE SHORT VERSION 1. Add Images (or drag the pictures onto the page area) 2. Drag the cards into the order you want 3. Create PDF WHICH PICTURES IT TAKES JPEG and PNG used exactly as they are, byte for byte WebP, GIF, BMP converted on the way in, because a PDF cannot carry them AVIF, HEIC only if your browser can open them at all A card says "converted" under it when its picture had to be re-encoded, and "turned upright" when a photo carried an EXIF tag saying which way up it belongs. Everything else is passed straight through: your JPEGs are not compressed a second time, so nothing loses quality here. ARRANGING THEM Drag a card move it anywhere in the sequence; the blue line shows where it will land The number in the the page it becomes. It is not the order you added corner them in, it is the order the PDF will have ↺ / ↻ on a card turn that picture a quarter at a time ✕ on a card take it out of the PDF (your file is untouched) By Name puts a numbered set straight: scan-2 comes before scan-10, which a plain alphabetical sort gets wrong By Date oldest first, using the date each file was last changed Reverse Order flips the whole sequence THE PAGE Size "Fit to picture" gives every page the exact shape of its own picture: nothing is cropped, and there are no white bands. Choose A4, Letter, Legal, A3 or A5 when the result has to be printed, filed or emailed as a standard document. Orientation Auto follows each picture, so a mixed set really does come out with some pages one way up and some the other. Portrait and Landscape force every page the same way. Margin white space around the picture, in millimetres. Placing "Fit inside" keeps the whole picture, leaving white space where the shapes do not match. "Fill the page" scales it up until the page is covered and crops what does not fit; the margin does not apply to it, because filling the page and leaving a border are opposite instructions. Orientation and Placing are switched off under "Fit to picture" - there the picture IS the page, so there is nothing for them to decide. THE CARD IS THE PAGE Each card draws the PAGE, not the picture: the same shape, the same margins, the same crop, the same turn. Change a setting and every card redraws. What you see on the cards is what the PDF will hold - you never have to save the file to find out what you asked for. SAVING "Create PDF" shows a summary first: how many pictures, how many pages, the page size and the name of the file it will write. Nothing is written until you press the button in that window. Your pictures are never modified. A new PDF is written beside them, in your Downloads folder. KEYBOARD SHORTCUTS Ctrl+O Add images Ctrl+Z / Ctrl+Y Undo / Redo Ctrl+E Create PDF NOTES - Undo covers the order and the turns. Removing a picture is the one thing it cannot bring back, which is why removing asks first. - File size follows the pictures. Ten phone photos make a PDF of roughly ten photos: the JPEGs go in as they are, so there is no hidden re-compression making it smaller, and no re-encoding making it bigger. A WebP or GIF that has to be converted may grow, especially one with transparency, which has to become a PNG. - Memory, as a rough guide: allow about 300MB plus a few times the total size of the pictures. Twenty phone photos are comfortable anywhere. If it ever runs out the browser closes the tab, and because your pictures are never written to, you lose the arrangement and nothing else. - Nothing is stored. No cookies, no database - closing the tab loses the arrangement, which is why there is a warning before you do. - This tool only writes PDFs, it never opens one. To combine finished PDFs use Vuiso Merge PDF, to drop or extract pages use Vuiso Split PDF, and to turn pages that came in sideways use Vuiso Rotate PDF. PRIVACY The file contains a Content-Security-Policy that forbids network connections entirely. That is enforced by the browser, not promised by us: open DevTools, watch the Network tab, and it stays empty. You can also disconnect from the internet and the tool still works. Verify the copy you hold matches the one published: Windows Get-FileHash "Vuiso Image to PDF.html" -Algorithm SHA256 macOS/Linux shasum -a 256 "Vuiso Image to PDF.html" Compare the result with the SHA-256 printed on the download page and in the .sha256.txt file next to this one. LICENCE See LICENSES.txt, which must stay alongside the tool.
