How it works
From JPG to PDF, in three steps
- 01
Choose JPGs
Drop one or more JPG photos in; each appears as a thumbnail in page order.
- 02
Arrange & set page size
Drag thumbnails to reorder, then pick fit-to-image, A4, or Letter.
- 03
Download PDF
Your PDF is assembled locally and downloads straight to your device.
To convert JPG to PDF, drop one or more JPG files into the box above. Each one shows up as a thumbnail in the order it'll appear in the finished PDF; drag a thumbnail to move it, or use the arrow buttons if dragging isn't convenient.
Choose a page size before building: "Fit to image" (the default) sizes each page to match its photo exactly, with no cropping or stretching. A4 and Letter fit the photo onto a standard page instead, scaled down and centered as needed. A margin option adds white space around the edges if you want it.
pdf-lib can embed a JPG's own compressed bytes directly, so nothing gets decoded and re-encoded along the way, and no additional compression is applied on top of what your photo already has. Click "Build PDF," and the document assembles locally in a background worker before downloading straight to your device.
When you need this
Scanned documents or receipts
A stack of receipt or document photos taken on a phone, saved as JPG, becomes one shareable PDF instead of a folder of loose images most expense or filing systems won't accept.
Photo sets for a form or portal
Some application forms, print shops, and online portals ask for a single PDF upload rather than several image attachments. This turns your JPGs into exactly that.
Keep a photo album as one file
Multiple JPGs from an event or a project are easier to send, print, or archive as one multi-page PDF than as a batch of separate photo files.
Worked example
Say you've photographed six receipts on your phone for an expense report, each saved as a JPG around 1.5 MB. The expense system only accepts a single PDF upload, not six separate images.
Drop all six into the box above. They land in drop order; drag any receipt that's out of sequence into place. Leave the page size on "Fit to image" so each receipt fills its own page at full resolution, and click "Build PDF." Within a couple of seconds you'll have one six-page PDF, ready to upload as the single file the form is asking for.
If the receipts need to print on standard paper instead, switch to A4 or Letter first; each photo gets centered and scaled to fit without distortion.
Format explainer
PDF is a document container, not an image compression format the way JPG is. This tool places each JPG as a full-page image on its own page, in the order you set. It does this by embedding the JPG's own compressed data directly into the PDF, skipping any decode-and-re-encode step, so the photo inside the PDF has exactly the same compression, and exactly the same quality, as your original file.
That's worth knowing if you're used to other PDF tools re-compressing images along the way: this one doesn't. If you need the photos back out of a PDF later instead, the PDF to JPG converter runs the process in reverse.
Frequently asked questions
Add your JPG files, put them in the right order, choose Fit to image, A4, or Letter, then select Build PDF. The conversion is free and happens locally in your browser.
Yes. You can convert JPG images to PDF online for free, without creating an account or uploading your photos to a server.
No. The JPG's own already-compressed bytes are embedded directly into the PDF, with no decoding or re-encoding step, so the image inside the PDF is identical in quality to your source file.
Yes, drop as many JPG files as you need, drag them into the order you want, and they land in one PDF, one photo per page.
"Fit to image" (the default) matches each page exactly to its photo, no cropping or stretching. Choose A4 or Letter instead for a document meant to print on standard paper; the photo scales down to fit and stays centered, never distorted.
No. Every step, reading the files, assembling the PDF, generating the download, happens locally in your browser, in a background worker. Nothing leaves your device.
No artificial limit. A very large batch is bounded only by your device's own memory, since all the files are held in the browser tab while the PDF is built.
The JPG's compressed image data goes into the PDF as-is, but PDF pages don't carry a photo's original EXIF metadata forward the way an image file does, so location and camera details won't be present in the resulting PDF.
