Frequently Asked Questions
Can I combine multiple JPG files into a single PDF?
Yes. You can select tens or hundreds of JPG files simultaneously. LocalDoc compiles each image as a consecutive page in a unified PDF document.
Does converting JPG to PDF reduce image resolution or clarity?
No. Original image data streams (DCT streams) are embedded into the PDF dictionary without lossy re-encoding, preserving 100% of your camera sharpness and fine document text.
What photo formats are supported?
The tool supports all standard raster image formats including .jpg, .jpeg, .jfif, .pjpeg, and .pjp. You can also mix JPG and PNG files smoothly.
Is there a limit on how many images I can convert?
There are no artificial usage paywalls or file count limits. Because conversion happens locally in your device RAM, you can merge as many images as your computer memory supports.
Are my private photos uploaded to remote servers?
No. LocalDoc operates with a strict zero-upload privacy architecture. All image processing, canvas operations, and PDF compilation execute locally on your machine.
