Convert JPG to PDF: what to know
A PDF is the format forms, portals and print shops actually accept when they ask for "a document": receipts photographed with a phone, a signed page, ID scans, a set of product photos for a listing. This page turns JPG files into a PDF on your own device — the photos are read from the file picker and written into a new PDF in the browser, so nothing is uploaded and there is no queue.
How to convert JPG to PDF
Drop your JPG files above or tap Choose images; you can add up to 20 at once. Put them in the order you want the pages to appear with the arrows next to each file, or use Sort by name for files numbered by a scanner or camera. Choose a page size — Fit to image keeps each page exactly the size of its photo, A4 and US Letter make a printable document — then click Create PDF and download the result.
Combine into one PDF is on by default, so every photo becomes one page of a single document. Turn it off to get one PDF per photo instead, which is what some upload forms want when they ask for "each page as a separate file".
The photos are stored unchanged
A JPG can be placed inside a PDF without decoding it: the PDF simply carries the original JPG bytes and tells the viewer where to draw them. Toolkitta does exactly that, so the PDF has the same quality as the photos you started with and is only slightly larger than their combined size. Nothing is re-compressed unless you ask for it.
Photos taken on a phone often carry an orientation flag rather than being physically rotated. Many tools ignore the flag and produce a PDF with sideways pages. Toolkitta reads the flag and rotates those photos upright before placing them, and says so in the file details.
When the PDF is too large
Twenty 4 MB photos make an 80 MB PDF, which email and most portals will refuse. Turn on Reduce file size: each photo is re-encoded as a JPG at quality 80 with the long side capped at 2480 pixels — about 300 dpi on an A4 page, plenty for print and far more than a screen needs. A typical phone photo drops from 3–5 MB to 400–700 KB, so the same document lands under 15 MB. If you need finer control, run the photos through the compressor first and send the results here.
Page size, orientation and margins
Fit to image makes a page the exact size of each photo (one point per pixel), so a PDF viewer shows the picture edge to edge with nothing cropped or padded. Pick A4 or US Letter for a document that prints predictably; Auto orientation turns landscape photos onto landscape pages, or force portrait/landscape for a uniform stack. Margins add 10 or 20 mm of white space, useful when the document will be printed and bound or when photos should not touch the paper edge.
Questions about JPG to PDF
- Are my photos uploaded?
- No. The PDF is assembled in your browser; the photos never leave your device. Close or reload the tab and the batch is gone.
- Does the quality drop?
- Not unless you turn on Reduce file size. By default the JPG bytes are embedded exactly as they are.
- Can I put several JPGs into one PDF?
- Yes — up to 20 per batch, in the order you set. Turn off Combine to get a separate PDF per photo instead.
- Is the EXIF data (location, camera) in the PDF?
- No. Orientation is applied to the pixels, but camera settings, GPS position and other metadata are not copied into the document.
