About JPG to PDF

Putting an image into a PDF is not a conversion in the usual sense: the picture is embedded whole, and the page is a frame drawn around it. A JPEG keeps its original compressed data — the same encoded stream that was in the file becomes the image object in the document — so the photo inside the PDF is bit-for-bit the photo you started with, at whatever quality your camera or scanner produced. PNGs are stored as lossless image data instead, which is right for screenshots and flat colour but yields a considerably larger document than the JPEG equivalent.

Page geometry is the choice worth thinking about. A fixed sheet, A4 or US Letter, is what you want when the result will be printed or filed with other paperwork: each picture is scaled to sit inside the margin box with its proportions kept, leaving white space where the shapes disagree. Fit-to-image instead sizes every page to its own picture, so nothing is letterboxed and nothing is cropped, at the cost of a document whose pages are all different shapes. Pictures are never enlarged past their natural size, so a small image stays small rather than being blown up into a blur.

Effective resolution is simply pixels divided by inches. A 3000-pixel-wide photograph across a seven-inch printable width lands near 430 DPI, well past what an office printer can resolve; the same photograph at 1000 pixels gives roughly 140 DPI, which reads soft on paper and slightly mushy on screen. Shrinking pictures before converting is therefore rarely worth the trouble for anything destined for print, and reducing a document scan below about 200 DPI starts to make small type genuinely hard to read. The exception is a photograph that will only ever be looked at on a screen, where the extra pixels do nothing but inflate the file that has to be emailed.

The privacy case is stronger here than for most PDF work, because of what people actually convert. Photographs of a passport, a driving licence, a payslip or a signed form are the archetypal input, and they are precisely the files that should not be posted to an unknown host to be processed and — supposedly — deleted afterwards. Nothing is transmitted from this page. One limitation deserves stating plainly: the result is a picture of a document rather than a document. It has no text layer, so it will not be searchable and no words can be selected or copied out of it.

Frequently asked questions

Which image formats can I use?

JPG and PNG. Each picture becomes one page, in the order you arrange them. If a file’s extension does not match its real contents, the decoder falls back to the other format instead of failing outright.

Are my photos uploaded?

No. They are read from disk by the browser and embedded into the document inside this tab. That matters more than usual here, because ID pages and payslips are among the most common things people convert this way.

Which page size should I choose?

A4 or Letter when the result will be printed or filed alongside other paperwork; fit-to-image when it will only ever be viewed, since that removes the white bands around pictures whose shape does not match the sheet.

Does converting reduce the quality of my photos?

A JPEG is embedded with its existing compression untouched, so there is no second round of loss. PNGs stay lossless. The only change is scale: anything larger than the page is reduced to fit, and anything smaller is left at its own size.

Can I search or select the text in the finished PDF?

No. The pages hold images, not characters, so there is nothing for a search to match. Making a photographed document searchable requires optical character recognition, which this tool does not perform.

How many images can I add, and does it work on a phone?

Dozens are fine, and mobile browsers are supported — choose pictures through the photo library or the Files app. The practical limit is memory, since every image is held while the document is assembled, and full-size camera originals add up quickly on a handset.
