How to Convert JPG to PDF Online
Converting a JPG or PNG image to PDF with RoarTools is fast and simple. Upload your image by dragging and dropping it into the upload area, clicking to browse, or pasting from clipboard with Ctrl+V. After the image loads, choose your PDF settings — page size, orientation, margin, and image quality. The page size options are A4 (standard international), Letter (US standard), or Fit to Image (the PDF page matches the exact image dimensions). Choose Portrait or Landscape orientation. Set the margin to None, Small, or Normal depending on whether you want white border around the image. Adjust the quality slider between 60 and 100 percent. Click Convert to PDF, and the PDF downloads instantly. All processing happens in your browser using PDF-lib — no image is uploaded to any server.
The output PDF contains your image centered on the selected page size with the chosen margin. If the image aspect ratio differs from the page, the image scales to fit within the margin area while preserving its proportions. This prevents stretching or cropping of your image.
Why Convert Image to PDF?
Images are sometimes required as PDF for document submission. Government portals and exam application systems often require a specific document type, and PDF is the most common. If you have scanned or photographed a document as a JPG, converting it to PDF makes it compatible with portals that only accept PDF uploads. Combining a professional appearance is another reason — a PDF looks more formal than a loose image file when submitting qualification documents or experience letters.
Sending multiple images as one file is easier when they are in PDF format. While this tool handles one image at a time, the Images to PDF tool lets you combine multiple images into a single PDF. PDF files are also more universally compatible for printing — most printers and print services accept PDF directly, while printing a JPEG sometimes requires extra steps. For portfolio submissions, research applications, or scholarship document uploads, PDF is often the required format.
JPG to PDF for Exam Document Submission
Indian competitive exam portals have specific requirements for document format. Many portals accept only PDF for certificate uploads, while requiring JPG or PNG specifically for photographs. Understanding which format is needed for each document type prevents rejected uploads. Use this JPG to PDF converter when you have a document photograph that needs to be submitted as PDF. Do not use it to convert your passport photo or signature — exam portals require those as JPG.
For UPSC, SSC, IBPS, SBI, RRB, and state PSC exams, certificates of qualification, identity proof, category certificate, and domicile certificate are typically uploaded as PDF. If you have these scanned as JPG images, convert them to PDF individually, then use the PDF Merge tool to combine them if the portal requires a single combined document. This workflow ensures all documents are in the correct format before submission.
Page Size and Format Guide
Choosing the right page size matters for document appearance. A4 is the international standard used in India, the UK, and most of the world — 210mm × 297mm. If your document scan matches A4 paper, choosing A4 page size produces a clean, properly proportioned PDF. Letter size is 216mm × 279mm, used in the US and Canada — slightly shorter than A4. Choose Fit to Image if the exact proportions of your image matter and you do not want any white border or scaling. For example, a certificate scanned at non-standard dimensions will look better in Fit to Image than stretched into an A4 page.
Landscape orientation is useful when your image is wider than it is tall — for example, a scanned bank statement or a panoramic document. Portrait orientation is the default for most documents. The margin setting adds white space around the image within the PDF page — Normal is recommended for a clean look, None removes all padding for images that fill the entire page.
