Your images never leave this tab.
Open your browser's developer tools, switch to the Network tab, and convert a file. You will see the encoder and its WebAssembly module load from this domain the first time, and then nothing — no upload, no image data, no request carrying your file anywhere. Turn off your Wi-Fi after the page loads and it still works.
Why TIFFs are so painful to work with
TIFF has been the scanning and print industry’s format since 1986, and it is very good at that job: it stores images losslessly, handles high bit depths, records the colour profile, and can hold many pages in one file. Archives, law firms, hospitals and print shops all standardised on it for good reasons.
None of those reasons apply once the file needs to leave that world. No browser will display a TIFF. Most web upload forms reject it. And the files are enormous — a single 300 DPI colour page stored losslessly runs to tens or hundreds of megabytes, which is more than most mail servers will accept.
Converting to JPG solves all three at once.
How to convert TIFF to JPG
- Drop your
.tifor.tifffiles onto the box above, click it to browse, or drop a whole folder of scans. - JPG is already selected as the output format on this page.
- Press Convert, then download the files individually or as a single ZIP.
The size reduction is usually the headline. A lossless 100 MB scan becomes a two-megabyte JPG that looks the same on screen. If you need it smaller still, set a pixel width under Resize — most scans are captured at far higher resolution than anything they are later used for.
Only the first page is converted
This is the one limitation worth knowing before you start. A TIFF can contain many images, and multi-page TIFFs are standard for scanned documents and fax archives. This converter decodes the first image in the file and produces one JPG from it. The remaining pages are not written.
For a single-page scan — which is most of them — this makes no difference. For a fifty-page scanned contract, split the file in a desktop tool first.
Choosing quality for a scan
What was on the paper decides this:
- Photographs, artwork, anything continuous-tone. Quality 82 is right, and it is what the page defaults to.
- Text, forms, line drawings, plans. Raise it to 92 or higher, or convert to PNG instead. JPEG compression puts a faint halo around hard black-on-white edges, which is precisely what scanned text is made of, and it makes small type look muddy.
The scans stay on your machine
The TIFF decoder is WebAssembly running in this tab. Nothing is transmitted, because there is no server here to transmit to. Given what TIFF is typically used for — medical images, legal discovery, archival digitisation, engineering drawings — that is not a small detail.
Frequently asked questions
- How do I convert TIFF to JPG for free?
- Drop your .tif or .tiff files onto the box at the top of this page — JPG is already selected — press Convert, and download the results. No account, no watermark, no daily limit and no file size cap, because the conversion runs on your own machine rather than on a server.
- Why can't my browser open TIFF files in the first place?
- No major browser has ever supported TIFF. It was designed in the mid-1980s for desktop publishing and scanners, not for the web, and it is less a single format than a container that can hold a dozen different compression schemes. This converter ships its own TIFF decoder compiled to WebAssembly, which is why it can read files your browser refuses to display.
- What happens to a multi-page TIFF?
- Only the first page is converted. TIFF can hold many images in one file — it is the standard format for multi-page scans and fax archives — but this converter reads the first one and produces a single JPG from it. If you need every page, split the TIFF first in a desktop tool.
- How much smaller will the JPG be?
- Usually dramatically smaller. TIFFs are frequently stored uncompressed or with lossless LZW compression, so a 300 DPI colour scan of a single page can easily be 100 MB. The same page as a quality-82 JPG is typically a couple of megabytes. Reductions of 50 to 100 times are ordinary.
- Should I use JPG or PNG for a scan?
- It depends what was scanned. For photographs and artwork, JPG — it is far smaller and the compression suits continuous tone. For scanned text, line drawings, forms and engineering plans, PNG is the better choice: JPEG puts ringing around the hard black-on-white edges that make text legible.
- Is there a file size limit?
- No. The file is decoded in your browser, so the only real limit is your machine's memory. Very large scans — think 600 DPI colour at poster size — will take a moment and use a lot of RAM while they are being processed, but they are not rejected.
- Are my scans uploaded anywhere?
- No. There is no upload endpoint on this site. That matters for this format in particular, because TIFF is what legal discovery, medical imaging and archival digitisation use — the documents people scan are very often ones that should not be handed to an anonymous web service.
Other conversions
Each converter opens with the right output format already selected, so the file you drop comes back in the format you came for.
Convert WebP to another format
Convert images to WebP
- Convert PNG to WebP Keep the transparency, drop most of the file size. Lossless mode is one click away if you need pixel-exact output.
- Convert JPG to WebP Typically 25-50% smaller than the same photo as a JPEG, at a quality most people cannot tell apart.
- Convert JPEG to WebP The same conversion as JPG — the two extensions are one format. Smaller files, same picture.
- Convert HEIC to WebP iPhone photos, converted in the browser. No app, no upload, and it works on iOS Safari where most converters do not.
- Convert AVIF to WebP Usually a compatibility move rather than a size one. WebP opens in more places than AVIF still does.
- Convert GIF to WebP Static GIFs convert cleanly and shrink hard. Animated GIFs convert to their first frame — and we will tell you when that happens.
- Convert TIFF to WebP Scans and print files, converted to something a browser can actually display.
- Convert BMP to WebP BMP stores pixels essentially uncompressed. Expect the file to get very substantially smaller.
- Convert SVG to WebP Turning vector into pixels. You choose the size, because a vector does not really have one.
Convert to PNG or JPG
- Convert HEIC to JPG Turn the photos your iPhone actually shot into the format everything else can open. The pictures never leave your device.
- Convert HEIC to PNG Convert iPhone photos into PNG when the software you are feeding demands it. Lossless, private, and free.
- Convert SVG to PNG Rasterize vector artwork into PNG at the exact size you need, with the transparent background intact.
- Convert SVG to JPG Rasterize vector artwork into JPG for the places that will not take anything else. Free, unlimited, nothing uploaded.
- Convert TIFF to PNG Convert archival scans into PNG without losing a pixel — the right choice when the page is text, plans or line art.
- Convert AVIF to JPG You downloaded an AVIF and nothing on your computer will open it. This turns it into a JPG that everything opens.
- Convert AVIF to PNG Convert AVIF into PNG for the software that has never heard of AVIF. Transparency intact, nothing uploaded.
- Convert GIF to PNG Convert GIF into PNG without losing a pixel — and escape the 256-colour palette for good.
- Convert GIF to JPG Convert GIF into JPG for the systems that insist on it. Free, unlimited, and nothing leaves your machine.
- Convert BMP to PNG Shrink uncompressed Windows bitmaps dramatically without losing a single pixel. Free, unlimited, nothing uploaded.
- Convert BMP to JPG Turn enormous uncompressed bitmaps into files you can actually send. Free, unlimited, and nothing leaves your machine.
