Step-by-step instructions

Convert on Mac with Preview
Open the JPG in Preview. Go to File → Export. Choose TIFF from the Format dropdown. Optionally select compression type (None, LZW, or ZIP — all lossless within the TIFF). Click Save. The resulting TIFF is lossless but will be 5–10 times larger than the JPG source.

Convert on Windows with Paint or IrfanView
Open the JPG in Paint. File → Save As → Other Formats. In the Save as type dropdown, choose TIFF. Click Save. Alternatively, use IrfanView (free, more format options): open the JPG, then File → Save As → TIF/TIFF. IrfanView lets you choose LZW compression for smaller TIFF files.

Convert via command line
FFmpeg: `ffmpeg -i input.jpg output.tiff`. ImageMagick: `convert input.jpg output.tiff` or with LZW compression: `convert input.jpg -compress LZW output.tiff`. For batch: `mogrify -format tiff *.jpg`. These tools are available on Mac, Windows, and Linux.

Understanding the limitations
Converting JPG to TIFF does NOT restore quality — the JPG compression artefacts are baked in. The TIFF will be lossless from this point forward, meaning no further quality loss during editing. The main reason to convert JPG to TIFF: to edit it extensively without accumulating additional compression damage each time you save.
Why convert JPG to TIFF?
Converting JPG to TIFF is the standard workflow step when you need to do extensive retouching, combine files for print, or meet requirements from a print service or publisher that mandates TIFF delivery.
Your files never leave your device
FormatDrop runs the conversion engine entirely inside your browser using WebAssembly. No file upload. No server. Nothing stored. You can verify this by opening DevTools → Network tab and watching: zero upload requests.
