Photos, screenshots, scanned pages, and other images are great — but PDFs are easier to share, print professionally, and submit to systems that require documents rather than images. Converting JPG to PDF bundles your images into a universally compatible document format in seconds.
Why Convert Images to PDF?
- Submit scanned documents to portals that only accept PDF
- Combine multiple photos into a single shareable file
- Send a professional-looking document rather than a loose image file
- Archive photos in a consistent, organized format
- Print photos at precise page sizes (A4, Letter, etc.)
- Protect images by adding a password after conversion using Protect PDF
How to Convert JPG to PDF at PDFToolShack
- Open the JPG to PDF tool
- Upload your images — JPG, PNG, or other image formats; add as many as you need
- Drag to reorder — arrange the images in the sequence you want them in the PDF
- Choose page size — A4, Letter, or fit to image
- Click Convert — your images are assembled into a PDF in your browser
- Download your PDF
Page Size Options: What to Choose
| Option | What It Does | Best For |
|---|---|---|
| Fit to image | Page is exactly the size of the image — no borders or scaling | Photos, artwork, when exact dimensions matter |
| A4 | Image is scaled to fit an A4 page (210 x 297mm) | Documents for European printing or submission |
| Letter | Image is scaled to fit a US Letter page (8.5 x 11 in) | Documents for US printing or submission |
For scanned documents that need to look like standard paper pages, choose A4 or Letter. For photos where you want to preserve the original dimensions, choose "Fit to image".
Converting Multiple Images Into One PDF
The tool accepts multiple images in a single session — drop them all in at once or add them one by one. Each image becomes one page in the resulting PDF, in the order you specify. This is the fastest way to assemble scanned pages, photo collections, or screenshot sequences into a single organized document.
If you later need to add more pages to the resulting PDF, you can use the Merge PDF tool to combine it with other files.
What Image Formats Are Supported?
The tool accepts JPG, JPEG, and PNG files. PNG files with transparent backgrounds are supported — the transparency is preserved or rendered with a white background in the PDF depending on the page size setting. If you have images in other formats (HEIC from iPhone, WebP, TIFF), convert them to JPG first using a free image converter.
Will the Image Quality Be Preserved?
Yes — the images are embedded in the PDF at their original resolution. No compression or quality reduction is applied during conversion. If the resulting PDF is larger than you'd like, you can run it through the Compress PDF tool afterward to reduce the file size.
Going the Other Direction: PDF to JPG
If you need to go the other way — extracting pages from a PDF as images — the PDF to JPG tool converts each PDF page into a separate JPG file. You can choose the resolution and convert all pages or just the ones you need.
- JPG to PDF converts one image or many into a single multi-page PDF document
- Drag to reorder images before converting to control page sequence
- Choose A4 or Letter for document submission; "Fit to image" for photos
- JPG and PNG are supported; convert other formats to JPG first
- Original image quality is preserved — compress afterward if needed
- Use Merge PDF to combine the result with other PDFs
