JPEG to PDF Conversion FAQ
Will background and colour fidelity be preserved?
+
Neither JPEG nor PDF carries an alpha channel, so the background renders as a solid colour and pixel colour data is preserved end-to-end.
Is the JPEG to PDF conversion reversible?
+
You can convert the PDF back to JPEG on this site. If either format involved is lossy, the round-trip is not bit-perfect even though it is visually or audibly close.
What output quality should I expect from JPEG to PDF?
+
Default settings target broadcast / web quality — visually identical to the source for most viewers. For archival use, pick the highest quality option in the converter settings.
What if the source is a scan with no real text in it?
+
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.
Is the PDF side of this conversion searchable?
+
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.
Is there a file-size limit when converting JPEG to PDF?
+
Free conversions have a size limit per file, set by the type of file, and the page tells you when a file is over it. A paid plan removes that limit, so much larger files can be converted.
Can I batch-convert several JPEG files to PDF at once?
+
Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.
What happens to my JPEG files after the conversion?
+
Uploaded files are processed on our own conversion servers, nobody looks at them, and they are not shared. The upload and the converted file are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
Will my PDF look the same on every device?
+
Yes. PDF is a fixed-layout format — the PDF renders identically on phones, tablets, laptops, and printers. That is the main reason to convert JPEG into PDF.
Do I need to install software to convert JPEG to PDF?
+
No. The converter runs entirely in your browser plus our cloud — no plugin, no install, no admin rights. It works on Windows, macOS, Linux, ChromeOS, iOS, and Android.
Do I need an account to convert JPEG to PDF?
+
Yes. One conversion an hour is free, with no account needed, for a file within the free size limit. A paid plan removes the hourly limit and the size limit, and lets you add several files to one job.
Is there an API for JPEG to PDF conversion?
+
Yes. Every conversion this site offers is also exposed via a JSON API — see /api/ for endpoints, authentication, and rate limits. JPEG to PDF is one of the supported pairs.
