What Is a JPG to PDF Converter?
A JPG to PDF converter takes one or more JPG images and combines them into a PDF document where each image becomes one page. This is useful for creating multi-page documents from photos, scans, or screenshots.
TweakFiles converts images to PDF entirely in your browser using pdf-lib. Your images are embedded at their original resolution — no downscaling or re-compression occurs. Your files never leave your device.
Common Use Cases

- Compile multiple pages of a scanned book into one file
- Create printable documents from image files
How TweakFiles JPG to PDF Works
TweakFiles uses pdf-lib to create a new PDF document and embed each uploaded image as a separate page. JPG and PNG images are embedded directly; WebP images are first decoded via the Canvas API and then embedded as JPG. Each page is sized to match the image dimensions. You can reorder images before conversion using the up/down arrows.
