What you should know
JPG to PDF turns a photo or a scanned image into a one-page PDF document. It is the format most online procedures require for supporting documents: a photographed ID card, an invoice snapped with a phone, a scanned certificate.
FileXvert embeds the JPEG image as it is in the PDF, without recompressing it: the quality is exactly that of the original photo. PNG is handled the same way, and WebP is converted along the way.
Strengths
- No recompression: the PDF's image is identical to the photo
- A4 page in the image's orientation, with a margin of about 8 mm
- A format accepted by forms that reject images
- Instant conversion, without sending the photo to a server
Limitations to know
- One image gives one page: to combine several photos, merge the PDFs afterwards in the PDF editor
- The text of a photographed document is not recognised (no OCR): it stays an image
- A small image is not enlarged beyond its size, so it does not turn blurry
- The PDF weighs as much as the photo: a 6 MB photo gives a 6 MB PDF
When to use it
Convert to PDF when a website or service requires that format for a supporting document, or to print a photo on a well-framed A4 page. If the file is too heavy for the form, first shrink the photo as a JPG with balanced reduction.
Quality, size and compatibility
The JPEG is copied byte for byte into the PDF: no additional loss. The image is centred and scaled to fit the A4 page, never enlarged beyond 96 dpi. The PDF therefore weighs barely more than the original photo.
Frequently asked questions
- Does the photo lose quality in the PDF?
- Not for a JPEG or a PNG: the image is embedded without recompression. Only WebP is re-encoded as a high-quality JPEG, since the PDF could not contain it otherwise.
- How do I put several photos in a single PDF?
- Convert each photo to PDF, then merge them in FileXvert's PDF editor, which also lets you reorder them before exporting.
