Why are TIFF files so large compared to JPGs?

TIFF is an uncompressed or losslessly compressed raster format designed for archiving raw scan detail, whereas JPG applies smart compression to minimize file size.

Is it safe to convert sensitive legal contracts and IDs with this tool?

Yes. Processing takes place exclusively inside your browser using client-side JavaScript. Your documents never upload to any remote server or database.

Can I convert both .tif and .tiff file extensions?

Yes. Both .tif and .tiff file formats are fully supported for conversion into standard JPG images.

Will text on scanned documents remain readable after converting to JPG?

Yes. Our conversion algorithm maintains sharp contrast and resolution so fine print, legal clauses, and stamps stay legible.

About This Tool

Convert heavy TIFF and TIF files from document scanners and professional cameras into lightweight, web-ready JPG images. While TIFF files provide pristine uncompressed quality for archival preservation, their huge file sizes make them impractical for email attachments, web uploads, and everyday viewing on mobile devices. Scanned documents often contain sensitive personal information like bank records, tax forms, passports, and signed legal agreements. Because this converter operates 100% locally within your browser, your scanned records never travel over the internet. You get instant conversion without exposing private documents to external server vulnerabilities. Reduce gigabytes of raw scanner output down to compact, clear JPEGs in moments. Process single pages or batch convert multi-page archives without artificial limits, subscription paywalls, or added watermarks.
