Convert TIFF to JPG
TIFF is common in scanners, fax software and professional photography, but browsers and most apps will not display it. Convert your TIFF files to universal JPG locally — scanned documents never leave your device.
100% private: files are processed in your browser and never uploaded to any server.
How it works
- Drop one or more TIFF files into the box above.
- Each file is decoded and re-saved as a high-quality JPG.
- Download your JPG files — ready to view, share or upload anywhere.
Where TIFF files come from
TIFF is the format of scanners, fax gateways, medical and scientific imaging, and archival systems. It survives in those places for good reasons: it can store images losslessly, hold multiple pages in one file, and carry extensive metadata. It is also the format your office multifunction device is most likely to email you, and the one library and government archives hand out.
The cost of all that capability is size and compatibility. A single lossless scanned page can run to tens of megabytes, and TIFF is not a web format — browsers do not display it, most upload forms reject it, and sending one by email is often impossible. Converting to JPEG is what makes the image usable outside the system that produced it.
What to expect from the conversion
The size drop is usually dramatic — a 30 MB scan becoming a JPEG of a couple of megabytes is entirely normal, because you are moving from lossless storage to lossy compression tuned for photographs. For a document scan intended to be read, that loss is invisible.
Two caveats are worth knowing. Multi-page TIFFs, common for scanned documents, hold several images in one file; JPEG holds exactly one, so a multi-page TIFF cannot become a single JPEG — if the pages belong together, a PDF is the right destination. And TIFF files using unusual internal compression or exotic colour spaces, particularly from specialised scientific equipment, may not decode in a browser at all.
Good to know
TIFF turns up in scanners, fax software and professional photography. It is usually stored uncompressed or losslessly, which is ideal for archiving and terrible for sharing — converting to JPG typically cuts 80–95% of the weight.
Multi-page TIFFs are common in document scanning, and only the first page is converted here. If you have a multi-page scan you need in full, convert page by page for now, or build a PDF from the individual images.
Scanned documents are among the more sensitive things people convert, which is worth remembering: the decoding happens in your browser, so a scanned contract or medical record is never uploaded anywhere.
Frequently asked questions
My TIFF has several pages — what happens?
The first page is converted. If you need every page of a multi-page scan, convert it page by page for now — multi-page support is on our roadmap.
Why are TIFF files so large?
TIFF usually stores images uncompressed or losslessly, which is ideal for archiving but heavy for sharing. Converting to JPG typically cuts the size by 80–95%.
Is this safe for scanned documents?
Yes — that is the point of Imgnest: the conversion runs inside your browser and your scans are never uploaded to any server.
Does the conversion lose quality?
The JPG is saved at high quality; for on-screen viewing and normal printing the difference is imperceptible. Keep the TIFF original if you need lossless archiving.
Can I convert a multi-page TIFF?
A JPEG holds one image, so multi-page TIFFs cannot be converted into a single JPEG. Convert the page you need, or use a PDF tool if the pages must stay together as one document.
Will text in a scanned document still be readable?
Yes, at reasonable quality settings. Scans of text compress well because they are mostly white, so you can usually keep full resolution and still land far below the original size.
