How this works in your browser
The PDF is built with pdf-lib in your browser. For JPEG sources this matters more than it sounds: a PDF can embed JPEG data directly, so pdf-lib writes the original compressed bytes straight into the document rather than decoding and re-encoding them. That is why the tool can promise no quality loss. PNG and WebP take a slightly different path since PDF has no native equivalent, but they are still embedded losslessly rather than converted to JPEG. Page size only controls the box the image is placed into and scaled to fit; it never resamples the embedded image data.

| Processing queue | None - starts instantly | Often, especially at peak times |
| Watermark on output | Never | Common on free plans |
| Usage limits | None - free, unlimited use | Often capped per day or file size |
| Works offline once loaded | Yes, for most tools | No - requires a live connection |
| Account required | No | Often, for anything beyond a trial |

Common ways to use JPG to PDF
Submitting photo-based documents
Turn photographed ID, receipts or signed forms into the single PDF that portals and HR systems usually require.

Making a simple photo album
Lay out a set of photos as pages in one shareable file that opens identically on any device.
Frequently asked questions
Can I mix JPG, PNG, and WebP in the same PDF?
Yes - all three formats are supported and can be combined freely in a single document.
Will the images be compressed or resized?
Images are embedded at their original resolution. You can choose a page size (A4, Letter, or fit-to-image) which may scale the image to fit the page, but the embedded data quality is not reduced.
Can I set the page orientation?
The tool automatically detects whether each image is portrait or landscape and sets the page orientation accordingly, or you can force a specific orientation in the options.
Why is the PDF larger than my images combined?
A PDF adds structure around each image (page objects, a cross-reference table, metadata), so a small overhead on top of the original image data is normal. If the total is much larger, compress the images first and then build the PDF.
Should I pick A4, Letter or fit-to-image?
Use A4 or Letter when the document will be printed or submitted somewhere with a page-size expectation. Use fit-to-image for screenshots and photos meant to be read on screen, since it avoids white margins around the picture.
Can I reorder images before converting?
Yes. Drag the thumbnails into the order you want before creating the PDF, and remove any you no longer need.
