Upload your JPG file(s)
Drag one or multiple JPG files onto the converter, or click to open the file picker. If you're combining multiple images into a single PDF (a common use case for document scans), select all images at once and the converter will add them as separate pages in order. You can reorder pages before converting.

Choose page size and orientation
Default output is A4 portrait (standard document size). Options typically include US Letter and A3 as well. For photos: choose a page size that matches your image's aspect ratio — a landscape photo fits better on landscape-oriented pages. If in doubt: use 'fit to image' mode, which creates a PDF page sized exactly to your image dimensions.

Convert and download
Click Convert. The PDF is generated instantly in your browser. Download the PDF file — it opens correctly in Adobe Reader, browser PDF viewers, iOS Files app, Android PDF viewers, and anywhere else PDFs are displayed.
Why convert JPG to PDF?
JPG-to-PDF conversion is one of the most common file conversion tasks — it appears whenever you scan a document with your phone camera and need to send it as a 'proper' document rather than a raw photo. Employers, government agencies, banks, and online portals often request submitted documents as PDFs rather than loose image files. PDF is also the practical format for combining multiple scanned pages into a single file rather than sending 5 separate JPGs. The conversion is straightforward: the JPG image data is embedded inside a PDF container at the original quality — no re-encoding occurs, so the image quality in the PDF is identical to the source JPG. The resulting PDF is essentially a PDF that contains an embedded image, which is why PDF-to-image conversion and back produces a round-trip without any additional quality loss.
Your files never leave your device
FormatDrop runs the conversion engine entirely inside your browser using WebAssembly. No file upload. No server. Nothing stored. You can verify this by opening DevTools → Network tab and watching: zero upload requests.
