Convertisseur TIFF en JPG — De la sortie de scanner au JPG adapté au web

The quality slider runs from 20 to 100 and controls how much the JPEG compresses fine detail. For scanned text documents, 70-80 keeps text sharp at a fraction of the TIFF's size; for scanned photos or fine art, use 85-95 to preserve tonal gradients and avoid visible blocking.

Use the background fill color swatch under Settings — JPEG has no alpha channel, so any transparent region in the source is painted with this color, white by default. Change it to match your document background (or your website's background color) if you're embedding the result on a colored page.

Yes — switch from Single file to Batch mode, drop in every TIFF you need converted, and the tool applies the same quality and background settings to all of them before packaging the results into one ZIP. Batch mode is a Premium feature; single-file conversion stays free and unlimited.

For black-and-white or text-heavy scanner output, pair quality 75-80 with a white background fill — this keeps files small enough to email while text stays legible. For color photo scans headed to print or archive, bump quality to 90+ so subtle color gradients don't band.

It appears only after you've changed the background fill away from the default, and clicking it snaps the color straight back to white (#ffffff) in a single click instead of reopening the color picker to dial white back in manually. This is handy after experimenting with a custom fill color for the transparent areas JPEG can't preserve, when you decide plain white is the safer choice after all.
