Convert JPG to PDF — free online converter
This JPG to PDF converter turns the images already on your device — JPG, JPEG or PNG — into one clean PDF, entirely in your browser. Add the files, keep their colours, and export a single document.
No sign-up, no watermark. Size targets are best-effort; the final file size is always shown.
Tap a page to crop, rotate or fix perspective. Drag ⠿ to reorder.
Export options
ID card: places the first two pages as front & back at ID-1 size on one A4 sheet. Use Edit to crop or align the four corners.
PNG is lossless, so target sizes do not apply.
Optional. Keeps the image ratio and never exceeds the page.
Everything runs in your browser — your files are never uploaded.
How do I convert a JPG to PDF for free?
Add one or more JPG, JPEG or PNG images to LensUp and export — you get one PDF with the pages in the order you set. It is free, runs entirely in your browser, and your files are never uploaded.
No photographing required: converting an existing file is the whole job here. When a form, an email or a print shop wants “one PDF, please” instead of loose pictures, add the images, put them in order, and download the merged file. Nothing is uploaded and no account is created.
The converter shares its engine with the LensUp document scanner, so the scanner’s cleanup — cropping, straightening, evening out lighting — is there when an image needs it, and stays out of the way when it doesn’t. A photo converted here keeps its colours by default.
How it works
- Add your imagesPick the JPG, JPEG or PNG files to convert — a single image or a whole set.
- Arrange and, only if needed, tidy upDrag pages into order. A crooked photo of a document can be straightened and cleaned; ordinary pictures skip the scan-style filters and keep their colours.
- Export one PDFDownload the merged PDF. If an upload limit applies, set a size target such as 200 KB — targets are applied on a best-effort basis.
A converter first — a scanner only when you want it
Most tools in this space assume you are photographing paper. To convert JPG to PDF you usually are not: the image already exists — a saved photo, a downloaded form, a WhatsApp picture — and the only missing step is packaging it as a PDF. That packaging is what this page does, with colours preserved and no scan-style filtering unless you ask for it.
Technically the export works like an office scanner’s output: each image is re-encoded as a full-size page inside a standard PDF that any reader, portal or printer accepts. Very large photos are scaled to a 2200 px long edge during processing — crisp for reading and printing, but the PDF embeds this processed page, not your original file byte for byte. The text in the pictures stays readable to a person yet is not selectable as text — LensUp deliberately does not do OCR.
JPG, JPEG, PNG — and the words people use for this job
JPEG and JPG are one format with two spellings, and both convert the same way; PNG images are accepted alongside them, and mixed sets are fine. Whether you call the task image to PDF, photo to PDF or convert JPG to PDF, it is the same operation: pictures in, one PDF out.
One image becomes a one-page PDF. Many images become a multi-page PDF — up to 50 pages in the order you arrange — which is how a stack of homework photos, receipts or contract pages turns into a single file worth sending.
When the upload form sets a size limit
Portals often cap uploads at 200 KB, 500 KB or similar. Set the size target before exporting and the converter compresses toward it in the browser, then reports the size it actually achieved. Targets are best-effort by design — an honest tool reduces quality step by step rather than promising an exact byte count.
For the strictest cases, such as a jpg to pdf 50kb requirement on a government or exam portal, the dedicated 50 KB page linked below walks through that exact workflow with the preset already applied.
Free, private, and built for paperwork
The converter is free, adds no watermark and needs no sign-up. Everything runs locally in the browser tab, which matters for the documents people actually convert — ID cards, certificates, signed forms: your files are never uploaded.
The same conversion exists in 20 languages through the scanner pages — the job people phrase as “convertir JPG en PDF” in French, “escanear foto a PDF” in Spanish, “transformar foto em PDF” in Portuguese or “scan foto ke PDF” in Indonesian is this exact workflow.
Frequently asked questions
Is this JPG to PDF converter really free?
Yes — free, with no watermark, no sign-up and no per-file charge. The conversion runs entirely in your browser and your images are never uploaded.
Does the PDF keep my image quality and colours?
Colours are preserved by default. Pages are re-encoded at high quality, with very large photos scaled to a 2200 px long edge — clearly readable and printable, though not a byte-identical copy of the original file. The text inside is not selectable — LensUp does not do OCR.
Can I combine many JPGs into a single PDF?
Yes. Add up to 50 images, drag them into the order you want, and export one merged PDF. A single image simply becomes a one-page PDF.
