How to convert JPG to PDF
Each image becomes one page, sized to the image, in the order you arrange them.
- Select your images. JPG and PNG, as many as you like.
- Put them in order. Use the arrows — the first image becomes page 1.
- Convert and download. One PDF containing every image.
Every page comes out exactly as big as its image
Each image is embedded and given a page whose width and height in PDF points equal the image's width and height in pixels — one pixel to one point, which is 72 to the inch. A 4032 × 3024 photo from a phone therefore produces a page 56 inches by 42. On screen nobody notices, because a viewer fits the page to the window, and printing scales to the paper. But the result is not an A4 document, and there is no fit-to-page option here.
The size of the file follows from the same rule. JPEG data is embedded exactly as it arrived, so a JPEG-only PDF comes to roughly the sum of the files plus a little structure. PNGs cannot work that way — PDF has no PNG image filter, so each one is decoded and stored as deflate-compressed pixels, which is regularly bulkier than the PNG was. A PDF of screenshots can come out larger than the images that went into it; Compress PDF is the answer to that.
The photo that arrives on its side
Phone cameras often store a picture in one orientation and add an EXIF tag telling software to turn it. Your photo gallery obeys that tag, and so does the browser's preview; the PDF writer does not, because it reads the dimensions straight out of the JPEG's own header. That is why an image that looked upright everywhere else can land sideways in the PDF. Nothing is damaged — Rotate PDF puts it right in a quarter turn, and that costs no quality at all.
The other snag is format. This tool picks between PNG and JPEG from the file's name and type, and the file picker offers only those two — but a file dragged onto the page is not filtered, so a HEIC or WebP renamed .jpg reaches the JPEG embedder and the conversion stops with an error about the image data. Scan to PDF takes the same photos through a canvas and re-encodes whatever the browser can decode, which is the easier route for HEIC on an iPhone or a Mac.
Questions
Are my photos re-compressed?
JPGs are embedded as they are, so there is no second round of compression and no extra quality loss. PNGs are embedded losslessly.
Can I use HEIC photos from my iPhone?
Convert them to JPG first — your phone can do this when sharing. PDF has no native HEIC support, so every tool must convert them somewhere.
Can I make every page A4 or Letter?
Not here. Each page takes the dimensions of its own image, so a mixed set of photos gives a mixed set of page sizes. Printers scale to fit the paper, which covers most uses, but if the document genuinely has to be A4 the images need resizing to that shape first.
Why is the PDF larger than the images I put into it?
PNGs are the usual cause: PDF has no PNG filter, so they are stored as deflate-compressed pixels, which is often less efficient than the PNG's own compression. JPEGs are embedded unchanged, so a JPEG-only PDF comes to about the sum of the files.
Can I put several images on one page?
No — one image per page, sized to that image. Two photos side by side need a layout step this tool does not have; combine them into a single image first, then convert.
Are my files uploaded to a server?
No. Every tool on this site runs inside your browser, using the same engine as the Folia desktop app. Your file is read from your disk into your browser’s memory, processed there, and handed back as a download. It never crosses the internet, so there is nothing for us to store, leak or hand over.
Is there a file size limit?
We impose none. The only ceiling is your own device’s memory, which differs from one computer to another — so we read what your browser reports about this machine and show the resulting limit on the page. Light tools like merge and rotate handle far more than heavy ones like OCR, which must render every page. For anything larger, Folia for Desktop has no limit at all.
Is it really free? Do I need an account?
Yes, and no. Every tool is free and unlimited, with no watermark and no sign-up. Ads pay for the site, and your own computer does the work, which costs us nothing. Signing in with a paid Folia plan simply removes the ads.
