TIFF to JPG Converter

TIFF to JPG conversion turns a large, lossless TIFF into a compact JPEG without uploading anything, because the file is read and re-encoded right inside your browser tab. People reach for this when a 20MB+ TIFF (a scanner master, archival scan, print master, or camera output) is too heavy for email, too slow for the web, and impossible to open on a phone that has never heard of the format. You get a smaller, universally-viewable JPEG (sometimes written JPG, sometimes JPEG, identical format) while the original TIFF bytes stay on your computer.

What this conversion actually does (and does NOT do)

TIFF is typically lossless: uncompressed, or packed with LZW or ZIP, storing full image data, which is exactly why it is so large. JPEG is lossy and compact, so the conversion goes one direction in size: dramatically smaller. The real-world delta is roughly 5-7x, so a 21MB TIFF commonly lands around 3-4MB as a JPEG at the same resolution. That reduction is the whole point for sharing and email.

It does NOT preserve transparency. JPEG has no alpha channel, so any transparent regions in a TIFF are flattened against a solid background (white by default) during conversion. If transparency matters, JPEG is the wrong target and you should convert the other way described below.

Two more things change that surprise people. First, color: TIFF can be CMYK (common for print masters), but JPEG for the web should be sRGB, so a correct converter applies a color transform to sRGB. Skip that step and colors look dull or shifted, which is the number-one "messed up colors" complaint when converting print TIFFs. Second, bit depth: TIFF can hold 16-bit-per-channel high-bit-depth data, while JPEG is 8-bit per channel, so converting reduces color depth. That is fine for viewing and sharing but loses editing headroom. The counterintuitive part: because re-encoding is lossy, you cannot losslessly recover the original TIFF detail from the JPEG, so keep the TIFF as your master and treat the JPEG as a derivative.

When to choose TIFF to JPG vs the alternative

Choose TIFF to JPG when the goal is sharing, email, the web, or social, where small size and universal compatibility win and lossy 8-bit output is perfectly acceptable. Keep the TIFF (or skip JPEG) when you need archival fidelity, large prints at 300dpi or higher, or further editing, since the lossless original holds detail and color depth a JPEG discards. If your TIFF has transparency you must keep, do not convert to JPEG at all: use TIFF to PNG instead, because PNG preserves the alpha channel that JPEG flattens.

How to convert

1. Drop one or many TIFF/TIF images into the converter; they are read locally, never uploaded.
2. The output format is pre-selected to JPEG. Use the quality slider to balance size against fidelity — 90-95 is near-lossless for web and email, while 75-85 is the web sweet spot.
3. Because JPEG has no alpha, any transparency in the source is flattened against a solid background during conversion.
4. Click Convert. A single file downloads directly; multiple files (including one JPEG per page from a multipage TIFF) download together as a ZIP, with no count cap.

No upload. It runs on your device.

The conversion engine is Rust compiled to WebAssembly, running inside your browser tab. When you drop a TIFF, the bytes are decoded and re-encoded in local memory, so there are zero network requests for the file itself. After the page has loaded once it works fully offline, on an airplane or an airgapped machine, and there is nothing to delete afterward because nothing was ever uploaded. You can confirm this yourself: open your browser DevTools, watch the Network tab while you convert, and you will see no file leave the device. This matters because TIFF is the format of choice for genuinely sensitive material, scanned legal contracts, medical and diagnostic images, and unpublished archival photography, none of which belongs on a stranger's server even briefly.

No limits

Convert unlimited batches with no file-count cap and no server-imposed size limit. There is no watermark stamped on output, no sign-up, and no ads.

Frequently asked questions

Does converting TIFF to JPG reduce quality?

Yes, because JPEG is a lossy format, so re-encoding discards some data and reduces 16-bit TIFF data to 8-bit per channel. Choosing 90% quality or higher keeps the artifacts effectively invisible for web and email while still capturing the size win, whereas very low quality introduces blocking artifacts.

How much smaller is a JPG compared to a TIFF?

The real-world reduction is roughly 5-7x at the same resolution, so a 21MB TIFF typically becomes a 3-4MB JPEG. The exact figure depends on image content and the quality level you pick on the slider.

Will my colors change when I convert a CMYK TIFF to JPG?

They can if the converter ignores color profiles, since print TIFFs are often CMYK while web JPEGs should be sRGB. A correct conversion applies a transform to sRGB so colors stay faithful; without it, print masters look dull or shifted, which is the most common color complaint for this conversion.

What happens to transparency when I convert TIFF to JPG?

Transparency is flattened against a solid background (white by default) because JPEG has no alpha channel. If you need to keep transparent areas, convert to PNG instead, since PNG preserves alpha while JPEG cannot.

How do I convert a multipage TIFF to JPG (one image per page)?

TIFF supports multipage files (common for scanned and faxed documents) but JPEG is single-image only, so each page becomes its own JPEG. The set of per-page JPEGs is delivered together as a ZIP so a multipage scan does not collapse into one image.

Can I convert TIFF to JPG without uploading my files anywhere?

Yes, the entire conversion runs in your browser via Rust compiled to WebAssembly, so the TIFF bytes never leave your device. You can verify there are zero file uploads by watching the Network tab in your browser DevTools during conversion.

Is it safe to convert sensitive or medical TIFF scans online?

It is safe here because nothing is transmitted: the file is processed locally and never reaches a server, so there is nothing for a third party to see or store. Server-based converters can only promise encryption in transit and later auto-deletion, which still means your scan sits on someone else's machine.

Can I batch convert many TIFF files to JPG at once?

Yes, drop dozens or hundreds of TIFF files together and they are all converted locally in one pass. When you convert multiple files the results download as a single ZIP, with no file-count limit imposed.

Is there a file size limit for converting TIFF to JPG here?

There is no server-imposed size or count cap because nothing is uploaded; the practical limit is your own device memory. That is a real advantage over hosted tools that cap free conversions at something like 50MB per file.

Should I keep my original TIFF after converting to JPG?

Yes, keep the TIFF as your archival and editing master, since you cannot losslessly recover its full detail or color depth from a JPEG. Treat the JPEG as a derivative made for sharing, web, and email.

Can I choose the JPEG quality / compression level?

Yes, a real quality slider lets you trade size against fidelity rather than locking you to a fixed preset. Use 90-95 for near-lossless output and 75-85 as the web sweet spot for the smallest file that still looks clean.

Does this work offline?

Yes, once the page has loaded the WebAssembly module is cached, so conversion works with no connection at all. You can run it on an airplane or an airgapped machine and no file data is ever sent anywhere.
