TIFF files from scanners are large, archival, and hard to share. This guide shows you how to convert TIFF to JPG on Mac, Windows, and iPhone — reducing file sizes by up to 90% while keeping quality high.
Frequently Asked Questions
Will I lose quality converting TIFF to JPG?
Some quality loss is unavoidable because JPG uses lossy compression. At quality settings of 85–95%, the difference is imperceptible on screen and for everyday printing. Keep the original TIFF for archival storage or professional print work — convert to JPG only for sharing and web use.
How do I convert TIFF to JPG on a Mac?
Open the TIFF in Preview, go to File → Export, choose JPEG from the format menu, set quality to 85 or higher, and click Save. For batch conversion, select multiple TIFFs in Finder, open them all in Preview, then use File → Export Selected Images.
How do I convert TIFF to JPG on Windows?
Open the TIFF in Paint, then go to File → Save As → JPEG Picture. Alternatively, open it in the Photos app and use the three-dot menu → Save as to choose JPEG format. For batch conversion, use an online tool like the free [Scanjet Document Converter](https://scanjet.app/document-converter/).
Can I convert TIFF to JPG for free online?
Yes. The free [Scanjet Document Converter](https://scanjet.app/document-converter/) converts TIFF to JPG in your browser with no signup and no file uploads — all processing happens on your device.
When should I keep TIFF instead of converting to JPG?
Keep TIFF for archival storage, professional printing, medical or legal documents, and images you plan to edit repeatedly. TIFF is lossless — every pixel is preserved. JPG degrades slightly with each save, so never use it as your working or archive format.
