When you need to organize scattered images into a unified, easy-to-share document, the Image to PDF tool can quickly convert common image formats like JPG, PNG, GIF, BMP, WEBP, and TIFF into standard PDF files. By intelligently parsing image pixel data and re-rendering it into PDF page objects, this tool outputs a single or multi-page PDF document, ensuring visual consistency across different devices.
Q: How many PDF files are generated when converting multiple images?
A: All images are merged into a single PDF file, with each image occupying one page.
Q: Can I edit the text content in the converted PDF?
A: No. The output is an image-based PDF. You will need an OCR tool to extract the text.
Each image must be smaller than 20MB. Black & White mode will lose grayscale details. Selecting "Fit to Image" may result in inconsistent PDF page sizes. Please download your generated files promptly to prevent data loss.
For scanned document images, we recommend selecting "Grayscale" mode to balance file size and readability. If you plan to print the output, use "Fill Page" mode to avoid white margins. Typical example: Converting 3 travel photos (JPG format, approx. 5MB each) to a color PDF using the "Keep Aspect Ratio" mode will generate a 3-page PDF document that preserves the original proportions of each image.
