Why People Convert Images to PDF
A picture of a receipt is just a JPG file; a picture of a receipt sent to your accountant is a PDF. The conversion is more about the container than the content. PDF gives you predictable page sizes, reliable printing, and a single attachment instead of a dozen image files. It is also what most expense systems, mortgage brokers, and council forms actually accept.
The tool above takes JPG, PNG, and WEBP files, lays each one out on its own page, and produces a single PDF. You can pick A4 (210 by 297mm) or US Letter (8.5 by 11 inches), set portrait or landscape, and choose how much margin sits around the image. Reordering happens by drag-and-drop, which is usually quicker than sorting filenames first.
Image Quality, File Size, and Colour
Inside a PDF, JPG images are stored using JPEG-DCT compression - the same lossy method as the source file. So a JPG embedded in a PDF stays roughly the same quality as the original; the PDF wrapper itself does not degrade it. PNGs are stored losslessly with Flate compression, which keeps screenshots and logos sharp at the cost of slightly larger files.
One trap: photo files from a modern phone are often in sRGB, but professional print workflows expect CMYK. If you are sending a PDF for print and the colours look washed out, that is the colour-model gap, not the converter. For print submissions, ask the printer what colour profile they want and convert the source images first.
Privacy When Converting Sensitive Photos
Conversion happens in your browser using pdf-lib. The images never leave your device, which is the only acceptable model for photos of passports, driving licences, P60s, or anything containing personal data. Online converters that upload to a server log every file they touch; for a P60 with your NI number on it, that is not a trade-off worth making.
If you also need to compress the source photos before adding them, the standalone [Image Compressor](/image-compressor) tool will do that. To go the other direction (split a PDF back into images), use [PDF to JPG](/pdf-to-jpg).
Frequently Asked Questions
What image formats can I convert?
JPG, PNG, and WEBP are supported. HEIC files from iPhones often need to be converted to JPG first, since most browsers do not decode HEIC natively. If you drag in an unsupported file, the tool will skip it and tell you which one was the problem.
Will the PDF be searchable?
No. A PDF made from images contains no extractable text, so search and copy-paste will not work. To make it searchable you would need OCR, which adds a text layer behind each image. This tool does not perform OCR; it produces a faithful but non-searchable PDF.
How big can my images be?
Each image can be up to about 50MB before browser memory starts to struggle, and the total combined size matters more than individual files. On a phone, expect to combine fewer or smaller images than you would on a laptop. If you hit a wall, compress the photos first.
Can I add text or notes to the PDF?
Not directly through this tool. JPG-to-PDF is purely a conversion. To add page numbers, use [Number PDF Pages](/number-pdf-pages) afterwards. To overlay a watermark or label, use a watermark tool on the output.
