What is TIFF and who uses it?
TIFF (Tagged Image File Format) is a lossless image format designed for professional photography, print production, and archiving. Unlike JPEG, TIFF stores images without compression artifacts, making it the standard output format for flatbed scanners, professional cameras in raw workflows, GIS and mapping software, and publishing pipelines where every pixel must be preserved exactly. TIFF files routinely reach 10–100 MB for a single image — a full-resolution scan from a document scanner can be 50 MB or more.
The trade-off is compatibility. Web browsers, email clients, and most social platforms do not support TIFF. If you need to attach a scanned document to an email or upload a scanned ID to a web form, TIFF will usually be rejected. Converting TIFF to JPG gives you a file that opens everywhere.
Convert TIFF to JPG without uploading
LocalJPG converts TIFF files in your browser using the native createImageBitmap API for decoding, then re-encodes to JPEG via MozJPEG. The file never leaves your device. This matters for scanned contracts, medical documents, or confidential records where uploading to a third-party converter is not acceptable.
Multi-page TIFF files (common from document scanners) are handled on a best-effort basis: the first page is extracted and converted. If you need all pages individually, split the TIFF first with a dedicated tool, then drop the individual files here.
How much does TIFF shrink when converted to JPG?
Very significantly. A 50 MB TIFF scan of an A4 document at 300 DPI typically becomes 500 KB–2 MB as a JPEG at quality 85 — a 25–100× reduction. The visual quality on screen and in email is essentially identical; the difference only shows at 400% zoom in a pixel-level comparison.
EXIF metadata from the TIFF (capture date, camera model, GPS if present) is preserved in the JPEG output. If your scanner writes resolution metadata (DPI), that is also carried across, which matters if the recipient's software uses it for print layout.
Batch converting TIFF files
Drop a folder of TIFF images and the converter processes them in parallel. Because TIFF files are large and uncompressed, the conversion is memory-intensive — if you are working with very high-resolution scans, process in batches of 10–20 to avoid memory pressure on older devices. Individual JPGs are always free. A one-time $0.50 unlocks a ZIP of all converted files for that session.
