TIFF earns its keep in exactly two places: professional print workflows and scanner output folders. Everywhere else it is a burden. A single flatbed scan can run to tens of megabytes, a folder of archival photos can swallow a hard drive, and the moment you try to email one or attach it to a web form something breaks — the upload times out, the recipient cannot preview it on a phone, or the site rejects the format outright. JPEG exists for precisely this situation, trading a small and usually invisible amount of fidelity for files that are dramatically smaller and open on every device made in the last twenty-five years.
People making this conversion are usually sitting on masters they intend to keep. A photographer sends client previews without handing over print-resolution files. An office turns scanned contracts into something any browser can display. A family digitization project comes back from the scanning service as a box of enormous TIFFs that nobody can actually share. The sensible pattern is identical in each case — archive the TIFF, distribute the JPEG — and this tool handles the second half without installing anything.
Conversion runs entirely inside your browser through WebAssembly, which matters when the TIFFs in question are contracts, medical records, or anything else you would hesitate to hand to an unknown server. Here there is no upload at all, no account, and no fee. The quality slider defaults to 85, a strong general-purpose setting: scanned text stays legible, photographs keep their detail, and file sizes shrink to a small fraction of the original. For line art or fine print, nudging the slider upward avoids the faint ringing JPEG can introduce around hard edges.
Two behaviors are worth knowing before you start. JPEG has no alpha channel, so any transparency in a TIFF is flattened into the image itself. And metadata is your call — there is an option to strip EXIF data during conversion, worth using when scans carry identifying details you would rather not send along with the file.
Why convert TIFF to JPEG?
- File sizes drop dramatically — JPEGs are typically a small fraction of the TIFF original
- JPEG opens everywhere: browsers, phones, email clients, office software, and upload forms
- A quality slider (default 85) lets you tune sharpness against size for scans versus photos
- Sensitive scans never leave your device — conversion happens fully in-browser
- Free, with no account, and every conversion runs on your own machine
How it works
- Step 1
Drop your files
Drag your TIFF files into the converter above, or click “Choose files”. Batches are welcome.
- Step 2
Pick your settings
JPEG is preselected. Adjust quality or size if you want, or keep the defaults.
- Step 3
Convert and download
Conversion runs locally in your browser. Download files individually or grab everything as a zip.
Frequently asked questions
- I am converting scanned contracts — do they get uploaded anywhere in the process?
- They do not. The converter is WebAssembly running locally in your browser; there is no server receiving files on the other end. Your scans are opened, converted, and saved without ever leaving your machine.
- How much quality will I actually lose going from TIFF to JPEG?
- At the default quality of 85, very little that you can see — photographs and document scans look essentially identical at normal viewing sizes. JPEG is lossy, though, so the safe workflow is to keep the TIFF as your archival master and treat the JPEG as the sharing copy. For critical output, raise the slider.
- What happens to transparency or layers in my TIFF?
- JPEG supports neither, so the image is flattened to a single opaque layer during conversion. If preserving an alpha channel matters, PNG is the better target format.
- Does the JPEG keep the TIFF metadata?
- You decide. There is an option to strip EXIF metadata during conversion, which removes details like capture device, timestamps, and location. Leave it off if you want that information to travel with the file, or turn it on for a cleaner, more private output.
- Why are TIFF files so large in the first place?
- TIFF prioritizes fidelity over size — it is frequently stored uncompressed or with lossless compression, often at high bit depths, because print and archival work demands it. That design is exactly why it makes a good master format and a poor sharing format.
