Add up to 20 images. Each file may be up to 15 MB; total selected size may be up to 60 MB.Images are processed locally. OpenStudyInfo does not receive or retain them. The PDF library code is loaded from a third-party CDN.
Separate photographs of assignment pages are difficult to upload, share and review. This tool places each image on its own PDF page, in the order you choose. It is useful for handwritten assignments, scanned notes, certificates and application documents when the receiving portal asks for one PDF instead of several image files.
The conversion happens inside your browser. OpenStudyInfo does not receive or retain the selected images. The PDF library code is loaded from a third-party CDN, so an internet connection is still required for the tool to load correctly.
📌 JPG to PDF Converter: Quick Overview
🔎 What Does a JPG to PDF Converter Do?
JPG and JPEG are two filename extensions for the same image format. Phones and cameras commonly save photographs in this format. One photograph is easy to share, but ten or twenty separate page images can arrive in the wrong order or be difficult for a submission portal to accept.
A JPG to PDF converter turns one image into a one-page PDF or combines several images into a multi-page document. Each selected image becomes a separate page. One PDF is easier to name, check, upload, email and keep as a backup than a folder of individual photographs.
📝 How to Convert JPG Images to PDF
Choose Your Images
Use Choose images and select one or more JPG, JPEG, PNG or WebP files. The tool accepts up to 20 images, with a limit of 15 MB per file and 60 MB in total.
Check Every Thumbnail
The tool displays each image with its filename, dimensions and size. Confirm that every required page has loaded and remove any duplicate or unrelated image.
Put Pages in the Correct Order
Use the up and down arrow buttons beside each thumbnail. Match the displayed order with the page numbers written on your assignment.
Select the Page Size
Choose A4, Letter or Fit each page to its image. A4 is usually the clearest starting point for academic pages, but the receiving portal’s instructions take priority.
Choose Orientation and Margin
Use automatic, portrait or landscape orientation. Then choose no margin, small, normal or wide margin according to the space you want around the image.
Set Resolution and Quality
Keep the original dimensions or limit the maximum image dimension to 2400, 1600 or 1200 pixels. The quality slider runs from 50% to 100% and starts at 88%.
Create and Download the PDF
Select Create PDF. When processing finishes, check the displayed page count and file size, then choose Download PDF.
Open the Downloaded File
The tool does not show a full PDF preview. Open the downloaded file in a PDF viewer and inspect every page before uploading it anywhere.
📷 Prepare Assignment Images Before Conversion
A converter can arrange pages and control PDF quality, but it cannot restore handwriting that is blurred, cropped or covered by a shadow. Preparing the photographs properly is the most important step.
- Use even light: Photograph pages near a window and avoid a strong shadow from your phone or hand.
- Keep the phone straight: Hold it directly above the page so that all four edges remain visible.
- Check the focus: Zoom into smaller handwriting after taking each photograph.
- Remove bad copies: Delete blurred, duplicate and incomplete photographs before opening the converter.
- Rotate pages first: Save every page upright in the gallery because this tool does not include a rotate button.
- Use clear numbering: Names such as 01, 02 and 03 make the selection order easier to understand.
- Read the submission rule: Confirm the required format, maximum size and naming pattern on the current official portal.
IGNOU, DU SOL, NIOS, universities and colleges can use different file limits or submission instructions. Creating a valid PDF does not automatically guarantee that every portal will accept it.
🗂️ How to Combine Multiple Images in the Correct Order
Add all the required pages and compare the thumbnails with the numbers written on the paper. The arrow controls move an image one position at a time, while the × button removes it. The first thumbnail becomes the first PDF page.
Portrait and landscape images can be included in the same file. With automatic orientation, each fixed A4 or Letter page is turned according to its image. The Fit option creates a page in the same aspect ratio as each image, so the physical page dimensions may differ across the final PDF.
After conversion, compare the page count shown by the tool with the number of selected images. Then open the file and scroll from the first page to the last. If the order is wrong, return to the tool, move the images and create a fresh PDF.
🖼️ Supported Image Formats
| Format | Supported? | Practical Advice |
|---|---|---|
| JPG | Yes | Suitable for photographed assignment pages and documents. |
| JPEG | Yes | JPEG is the same image format as JPG; no renaming is required. |
| PNG | Yes | Transparency is placed on white because images are embedded as JPEG. |
| WebP | Yes | Useful for compatible web images and screenshots. |
| HEIC | No | Export or convert the iPhone image to JPG before selecting it. |
| GIF, BMP or TIFF | No | Save the required page as JPG, PNG or WebP first. |
⚙️ Best PDF Settings for Common Uses
| Use Case | Good Starting Settings | What to Check |
|---|---|---|
| Assignment submission | A4, portrait or auto, normal margin, 2400 px, 88% quality | Small handwriting and portal file-size limit |
| Scanned notes | A4, auto orientation, small or normal margin | Page order, shadows and cropped edges |
| Certificate or application document | A4, auto orientation, 2400 px or original | Names, numbers, stamps and signatures remain readable |
| Email sharing | A4, 1600–2400 px, 80–88% quality | Readable text with a manageable attachment size |
| Wide photographs | Fit or landscape, suitable margin | Image is not unnecessarily reduced |
| Printing | A4 or Letter matching the paper, higher quality | Print one page before producing several copies |
These are starting points, not universal submission rules. If the PDF is too large, first try 1600 pixels or a slightly lower quality. If small text becomes unclear, return to 2400 pixels or the original dimensions and increase quality.

✅ Check the PDF Before Submission
- The PDF page count matches the number of required pages.
- Pages follow the written sequence from beginning to end.
- Text is readable at normal zoom and no edge is cropped.
- No page is sideways, duplicated or missing.
- The filename follows any rule given by the institution.
- The final size is within the receiving portal’s limit.
- The PDF opens successfully in a second viewer or device.
- No unrelated photograph or unnecessary personal information is included.
- A backup copy of the PDF and original images is saved.
🔒 Privacy and File Safety
The tool reads and converts the images locally in your browser. It does not upload the selected files to OpenStudyInfo or retain them. The browser creates the downloadable PDF on your device. The PDF library itself is loaded from a third-party CDN, so the page needs an internet connection when that library is not already cached.
- Check that the address begins with openstudyinfo.com before selecting files.
- Avoid working with sensitive documents on a public or shared computer.
- Add only the pages required for the intended submission.
- Delete unneeded local copies from a shared device after downloading the PDF.
- Do not treat browser-side processing as a reason to ignore ordinary device security.
