What this does
It turns images into a PDF: one picture or a folder of scans in, one document out, each image on its own page in the order you choose. JPEG and PNG go in; a single file named after your photo, or a multi-page images.pdf, comes out.
The conversion happens in your browser, which is worth pausing on because of what people actually feed tools like this: photographed passports, signed contracts, prescriptions, utility bills for proving an address. The typical converter site uploads all of that to its servers and asks you to trust a deletion policy. Here there is no server in the transaction at all; the PDF is assembled on your own processor and the download is handed from one part of your browser to another.
How to use it
- Drop your images onto the tool, or press “Choose images”. Add more at any point; each row shows a thumbnail, the pixel size and the file size once the image has been read.
- Put them in order. Drag a row, or use the arrows; the numbers on the left are the page order.
- Pick a page size: exactly each image, A4, or US Letter, with an optional half-inch margin on the paper sizes.
- Press “Make the PDF”, then download. One image downloads as its own name with a .pdf ending; several download as images.pdf.
Files that cannot be converted are refused by name with the reason: not an image at all, too damaged to read, or a format the tool will not silently re-encode.
Nothing is re-encoded, and you can check
The claim converter tools usually make, “no quality loss”, is here a measurable property rather than a promise. A JPEG’s compressed stream is placed into the PDF byte for byte; the file is not decoded, resized or re-compressed on the way through, and the test suite proves it by finding the input’s exact bytes inside the output document. PNG pixels travel losslessly in the same way. This is also why the tool has no quality slider: there is no quality decision being made.
Two consequences are worth knowing. The PDF is roughly the size of the images that went in, so a hundred phone photos make a genuinely large document; if size matters more than pixels, run them through the image compressor first, where the trade is made visibly and by your choice. And the page size options never touch the image data: they decide how large the picture is drawn on the page, not how many pixels it has.
Paper sizes, for things that will be printed
“Same as each image” is the digital-native option: every page is exactly its picture. For paper, A4 and US Letter fit each image onto a sheet, centred, turning the sheet landscape when the picture is wider than tall, and the margin option keeps a half inch clear all round for printers that cannot reach the paper’s edge. Mixed batches are fine: each page makes its own orientation decision from its own image.
When it matters
Scans are the big one: applications, tenancies and insurers ask for “one PDF” and phones produce one JPEG per photo. Receipts photographed through a month become one expenses document. Artwork and photography travel better as a PDF portfolio than as a folder of files that open in whatever order the recipient’s machine prefers. In each case the pictures already say everything; this tool just changes the envelope.
Limitations
JPEG and PNG only. WebP and HEIC would need re-encoding, which this tool refuses to do silently; the FAQ says how to convert each first.
One image per page. Contact sheets, collages and multiple images per page are layout work, and a layout tool should be honest about being one. This is not it.
No compression. The PDF is as big as its pictures. That is the no-recompression promise seen from the other side; the compressor exists for when the trade should go the other way.
Memory is the ceiling. Every image is held in your device’s memory while you arrange and build. Batches of ordinary photos are invisible; hundreds of full-resolution scans at once may not be.
