TIFF to JPG Converter - Convert TIF Files to JPG Free Online

Convert TIFF to JPG in your browser, including scans and print files no browser can open on its own. LZW, PackBits, Deflate, fax and CMYK TIFFs are all decoded locally, and nothing is uploaded.

What TIFF to JPG Does

This tool decodes your TIFF in the browser and re-encodes the pixels with the browser's own JPG encoder. The decoding half is the part that has to be built rather than borrowed: no browser has ever shipped a TIFF decoder, which is why a .tif dropped onto a web page shows a broken image icon and why most online converters upload your file to a server to do the job. Here the decode runs in JavaScript on your own machine. TIFF is not one format but a container with a long list of variants, so what arrives can be raw uncompressed pixels, LZW or PackBits or Deflate compressed strips, a CCITT group 3 or group 4 fax bitmap, or JPEG data wrapped in a TIFF header — at 1, 8 or 16 bits per channel, in greyscale, palette, RGB or CMYK. All of those are read here and normalised to RGB before encoding. Two consequences of the target format are worth stating up front. JPG stores 8 bits per channel, so a 16-bit scan is reduced to 8 bits, and JPG has no alpha channel, so a TIFF carrying an alpha sample is composited onto white. Output width and height always match the input exactly, and the Quality slider (1 to 100, default 92) controls how aggressively the encoder discards detail.

Why You'd Convert TIFF to JPG

TIFF is the archival and prepress format: it keeps everything, at a size to match. JPG is what the rest of the world can actually open.

Make scans, prepress artwork, and microscope or satellite captures viewable on any device, since browsers and phones cannot display TIFF at all

Cut a 40 MB scan down to a couple of megabytes so it fits an email attachment or an upload form

Put a photograph from a print workflow on a website, where TIFF is not a supported image format

Get a document or archive of scans into a format that shared drives, messaging apps, and phone galleries will preview

How to Convert TIFF to JPG

Four steps, all of them local — the TIFF is decoded, re-encoded, and handed back without ever touching a server.

Drop in one .tif or .tiff file or a whole folder of them — every file in the run uses the same settings

Set the Quality slider; 92 is the default, while 75-85 gives noticeably smaller files

Apply the conversion — the button reads "Converting..." while the decoder and encoder work through your files

Download each JPG on its own, or take the whole batch as a single ZIP

Frequently Asked Questions

No browser has ever implemented TIFF. Chrome, Firefox, Safari and Edge decode JPG, PNG, GIF, WebP and AVIF, and treat a .tif as a file to download rather than an image to display. The format was designed in the 1980s for scanners and prepress, it accumulated dozens of optional variants along the way, and it never became a web format, so nobody built it in. That is exactly why this page needs a dedicated decoder written in JavaScript instead of handing the file to the browser like the other converters here do.

Because TIFF is built to keep everything. Plenty of TIFFs are stored with no compression at all, so the file is simply width times height times bytes per pixel; a 300 DPI A4 scan in colour is around 25 MB before anything else is added. Even the compressed variants are lossless, meaning they only pack the data more tightly rather than discarding any of it, so a photographic scan rarely shrinks below half its raw size. TIFFs also routinely hold 16 bits per channel instead of 8, doubling the data again, and can carry alpha channels, embedded color profiles, and multiple pages in one file.

No — only the first page. TIFF is a container that can chain any number of images together, which is how multi-page scans and fax archives are stored, but this converter reads page one and produces a single JPG from it. The remaining pages are ignored, silently, so if a multi-page file gives you what looks like an incomplete result, that is why. To get every page out, split the file first with a desktop tool such as ImageMagick or IrfanView, then convert the resulting single-page TIFFs here as a batch.

It is converted to RGB, because JPG on the web is an RGB format and the browser's encoder will not write CMYK data. The conversion here is a direct arithmetic one and does not apply an ICC profile, so colors will be close but not colorimetrically exact — saturated cyans, rich blacks, and spot-like colors are where you will notice the shift most. For proofing or anything that is going back to a printer, keep the original TIFF and convert with a color-managed application instead. For putting a print image on screen or in a document, the result is perfectly usable.

Uncompressed, LZW, PackBits, Deflate/ZIP, CCITT group 3 and group 4 fax, and JPEG-compressed TIFFs are all decoded, in greyscale, palette, RGB, CMYK or YCbCr, at 1, 8 or 16 bits per channel. What is refused is the long tail: JPEG 2000 inside TIFF, CIE Lab and other extended color spaces, transparency-mask images, and a handful of proprietary schemes. The converter checks the header before decoding and stops with an error rather than producing a black or blank JPG, which is the failure mode most TIFF readers give you instead. Re-saving the file as an uncompressed or LZW TIFF from any image editor will get it through.

Yes, some. TIFF is lossless and holds the original pixel values exactly; JPG is lossy and always discards a portion of the fine detail. Start at the default of 92 for photographic scans, where the difference is very hard to see. Drop to 75-85 when size matters more than pixel-level fidelity. Scanned text, line art, and screenshots show the loss most clearly, because sharp black-on-white edges are what JPG compression handles worst — for those, quality 95 or more is worth the extra kilobytes. Note also that a 16-bit TIFF is reduced to 8 bits per channel regardless of the quality setting, since that is all JPG stores.

It is filled with white. A TIFF can carry an alpha channel as an extra sample per pixel, but JPG has no alpha channel at all, so transparency cannot survive the conversion in any form. This tool composites your image onto a white canvas before encoding, which is why transparent regions come out white rather than black or corrupted. If you need the alpha data preserved, convert to PNG or WebP instead — both store transparency properly.

No. Both the TIFF decode and the JPG encode run in your browser, so the image data never leaves your device. That matters more than usual for this format: TIFFs are what scanners, medical imaging systems, legal document archives and prepress houses produce, and those files are frequently confidential. It also means you can convert as many at once as your device's memory allows, with no upload cap — though large multi-hundred-megapixel scans are memory-hungry to decode, so very big batches may run slowly.
