JPG is re-encoded at the chosen quality; PNG keeps transparency. Everything is processed locally - images are never uploaded.
About this tool
Turning a set of pictures into one PDF is how you archive scans, print photos or submit supporting documents. This tool builds the PDF with jsPDF directly in your browser: pick A4 pages (image centred with margins) or one page per image size, reorder with the arrow buttons, and export a single file.
JPG is re-encoded at the quality you choose to control file size, while PNG keeps transparency. Unlike online converters there is no upload step: images are read and written entirely in device memory, so the tool keeps working offline and scans of IDs or contracts never leave your device.

Frequently asked questions
- How do I make the PDF A4 size?
- Choose the A4 page mode: every image is scaled proportionally and centred on an A4 page with margins, which is ideal for printing. Landscape images automatically use landscape A4. Pick the image-size mode if you want pages that match each picture exactly.
- Does JPG to PDF lose quality?
- It depends on the quality setting: the default 90% re-encode is effectively invisible, while higher quality means larger files. For a fully lossless result, convert the images to PNG first - PNG data is embedded without loss.
- Can I change the order of the images?
- Yes. Every row has up and down buttons, so arrange them in the final page order before exporting. You can also remove any image you no longer need.
- Are my images uploaded to a server?
- No. The PDF is generated entirely by jsPDF inside your browser and the images only exist in device memory. It works offline, so scans of IDs and contracts stay on your device.
