Searching for an image to PDF converter mostly returns tools that work the same way: you upload your pictures, a server builds the PDF, and you download the result. iLovePDF, Smallpdf and Adobe's online converter all follow that pattern. For holiday photos that is fine. For a scanned passport, a signed contract, a receipt or a medical letter, handing the originals to a third-party server is a real trade-off, and it is one you can avoid.
iLoveDevTools's Image to PDF builds the PDF inside your browser tab. The images are decoded by your browser and assembled with pdf-lib locally. Nothing is uploaded, there is no account, and there is no daily limit to run into.
It accepts JPG, PNG, WebP, GIF, BMP and AVIF in any mix, so screenshots, camera photos and images saved from the web can share one document. You drag the thumbnails into the order you want, then choose a page size: fit each page to its image, A4, or US Letter. Orientation can follow each image automatically or be forced, and a margin of none, small or normal keeps images off the paper edge. On a fixed page size each image is scaled to fit inside the margins and centred, with its proportions kept.
JPG and PNG files are embedded as they are, with no recompression, so there is no quality loss. WebP, GIF, BMP and AVIF are decoded and stored losslessly as PNG, which keeps them sharp but can make the PDF bigger than the sources; if that matters, the Compress PDF tool brings it back down. Phone photos that are stored sideways with an EXIF rotation flag are turned upright automatically.
The JPG to PDF tool is the simpler one: JPG and PNG only, and every page is exactly the size of its image. Image to PDF adds the other formats and real page layout, which is what you want when the result will be printed or sent as a document.
Be honest about the trade. The browser can only convert what it can decode, so HEIC photos from an iPhone are not supported here; export them as JPG first, or switch the camera to the Most Compatible format. Animated GIFs become a single still frame. Online services also bundle extras this tool does not have, such as cloud storage, scanning apps, OCR on the result and batch jobs across hundreds of files. If you need those, a hosted service is the better fit, and our OCR PDF tool covers text recognition in the browser if you only need that part.
If the images are private, or you just want a PDF now without an account, the browser version is hard to beat. Combine the pages, check the order, download, and the photos never leave your device. Need to merge the result with other documents afterwards? The Merge PDF tool does that the same way.
