TIF to JPG

What is TIFF?

TIFF — Tagged Image File Format — is one of the oldest and most flexible raster formats still in active use. Designed in 1986 by what became Aldus and now lives at Adobe, it was built as a container format for scanners, desktop publishing and print. A single TIFF can hold an uncompressed 24-bit photograph, a 1-bit fax page, a multi-page scanned document, a multi-resolution pyramid for GIS imagery, or a 16-bit-per-channel master from a medical or scientific instrument. The format is lossless, extensible through tags, and supported by every serious imaging application — which is exactly why it has outlived its contemporaries as the standard for archival image storage.

What is JPG?

JPG (also written JPEG) is the universal photographic format for the web, email, consumer cameras and print proofs. It uses lossy DCT-based compression — visual detail is discarded to shrink the file — but the trade-off is so well tuned that high-quality JPG remains visually indistinguishable from its source for almost every photographic image. Every browser, CMS, document tool, social platform, phone and printer understands JPG. That ubiquity, combined with its compact files, is why TIFFs end up needing to be converted to JPG before they can be shared.

Why convert TIFF to JPG?

Size is the headline reason. A 300 DPI A4 scan as uncompressed TIFF is 25-50 MB. The same scan as JPG at 92% quality is 1-3 MB with no visible loss. Email attachments, web uploads, content systems and cloud storage all have practical limits that TIFFs blow through immediately — the JPG conversion is almost always necessary just to move the file.

Compatibility is the second. Most consumer software still treats TIFF as a specialist format. Email clients display them inconsistently or not at all. Web browsers refuse to render TIFFs inline — every img tag pointing at a TIFF returns a broken icon. WordPress and most CMS plugins reject TIFF uploads. Outlook and Gmail strip the embedded preview. Social platforms won’t accept them. Converting to JPG removes that whole class of friction.

Workflow is the third. Photographers often archive masters as TIFF and deliver as JPG; scanning workflows produce TIFF first and convert later; print prep produces TIFF and the web equivalent ships as JPG. The TIFF-to-JPG step is one of the most-run operations in commercial imaging.

How to use this TIFF to JPG converter

1. Drop your TIFF file onto the dropzone, or click to browse.
2. Note the multi-page limitation banner. If your TIFF holds several pages — common for scanned documents — only the first page is converted.
3. Adjust the JPG quality slider. The default of 92% is near-lossless for scans and photographs; drop to 80% for a much smaller file with no visible loss on most content.
4. Click Convert to JPG to run the decoder and encoder.
5. Inspect the converted preview — the caption reports the new size and how it compares to the TIFF. Expect a dramatic reduction.
6. Click Download JPG to save the file.

Quality tips for TIFF to JPG

If you are converting an archival or scanner TIFF, the quality bottleneck is the JPG encoder, not the TIFF decode. Stay at 88-92% for any scan or photograph you intend to keep — anything lower will introduce compression artefacts in skin tones, sky gradients and printed text.

If the TIFF was already saved at low resolution or with a lossy internal compression (rare, but possible), the JPG inherits whatever the TIFF contained — JPG cannot recover detail that is not in the source. For the cleanest result, work from the highest-quality TIFF available, ideally the original scanner or camera export rather than a downsampled copy.

Privacy

Your TIFF file never leaves your device. The decoder, the canvas redraw, the JPG re-encode and the download all run locally in your browser. The page issues no network requests after it loads, which the Network panel in any browser’s DevTools will confirm. The same workflow runs identically offline once the page has been opened.

Browser compatibility

The TIFF decoder this page uses is UTIF.js, a small (~50 KB) pure-JavaScript library that is lazy-loaded the moment you pick a file — it does not ship until the page actually needs it. JPG encoding works in every browser through the standard canvas API. The converter behaves identically in Chrome, Firefox, Safari, Edge and every modern Chromium variant; the only failure modes are corrupt TIFFs and exotic compression codecs (rare LZW variants, JPEG-in-TIFF), for which the converter shows a clear error and asks you to re-export from your source app.
