Convert JPEG to PDF

Then the conversion produces a picture of the text rather than the text itself, and searching it finds nothing. Run /pdf-ocr/ to add a recognised text layer first; optical character recognition turns the scanned pixels into selectable, searchable characters that the conversion can then carry through properly.

EXIF travels with the embedded image data, which means GPS coordinates can end up inside a document you intend to publish. Use the strip-metadata option during conversion if the PDF is going anywhere public — once it is embedded it is no longer obvious that it is there.

Slightly, if the image is in CMYK. A JPEG can carry print colour, and a document renders on a screen, so the conversion maps those inks into RGB — and the ink gamut contains deep cyans and rich blacks that a screen cannot reproduce, which come back a little duller. Images already in RGB pass through untouched. If the document is heading for a printer rather than a screen, convert late and keep the CMYK original for the press. JPEG shares every JPG limitation — no alpha, generational loss on re-save — with the added nuisance of software that treats the two extensions differently.

It depends entirely on whether real text is present. A PDF generated from a document carries an actual text layer and is searchable; a PDF built from scans or images is a picture of text and is not, until OCR adds a layer. /pdf-ocr/ does that, and it is worth running before any conversion that expects to read the words.

Yes for text-bearing JPEG (DOCX, ODT, HTML, TXT) — fonts are embedded into the PDF so the output looks identical on every viewer. Image-only JPEG (JPG, PNG) just centers the image on the page; layout is N/A.

Yes — drop multiple JPEG files into the upload zone and choose the "merge into one PDF" option. They appear as sequential pages in the PDF in upload order; drag-to-reorder is supported before conversion.

Defaults: A4 portrait (international) or letter portrait (US). The advanced options expose page-size (A3, A4, A5, letter, legal, tabloid, custom) and orientation (portrait / landscape). For image JPEG, "auto-fit" picks orientation to match the source aspect ratio.

Yes for JPEG formats that have real hyperlink metadata (DOCX, ODT, HTML). Image-based JPEG (JPG, PNG, TIFF) have no hyperlinks to preserve. The PDF file uses standard PDF URL actions so links work in every PDF reader.

Yes when the JPEG contains real text (DOCX, ODT, HTML, TXT). Image-based JPEG produces an image-only PDF — to make it searchable, use /pdf-ocr/ after conversion to run optical character recognition.

Not in this tool — convert JPEG to PDF first, then use /pdf-protect/ to add a password, watermark, or restrict editing. Splitting the operations makes it easy to reconvert without re-typing the password.

Depends on the JPEG. A 10-page DOCX with embedded fonts produces a 200-400 KB PDF. A 10-image JPG batch at full resolution produces a 5-20 MB PDF. The advanced options expose a "compress images in PDF" toggle that recompresses embedded images at JPG quality 85.
