Convert TIFF Scans and Photos to JPG
Decodes TIFF files with the UTIF library and re-encodes them as JPG at a quality you choose. Turns large, awkward-to-open scans into lightweight images that open anywhere — without uploading the file.
About the TIFF to JPG Converter
TIFF is the format scanners, fax gateways and archives reach for, because it stores images at full quality and can hold multiple pages. It is also large, not viewable in most web contexts, and awkward to email — which is why the usual next step is a JPG. This converter decodes the TIFF in the browser using UTIF, a dedicated TIFF library, and re-encodes it as a JPG at the quality you set.
Because the output is JPG, a quality slider is offered, defaulting to 90 percent. That is high enough to keep a scan crisp while producing a file a fraction of the TIFF's size. Lower it for something that only needs to be viewed on screen; keep it high for a scan where fine text or detail matters.
Key Features
- Dedicated TIFF decoder: UTIF handles the many internal variants of TIFF — different compression schemes and bit depths — that the browser's own image support will not open.
- Adjustable JPG quality: A slider from low to high, defaulting to 90 percent, lets you balance file size against fidelity for the specific scan.
- Large size reduction: A multi-megabyte TIFF scan typically becomes a JPG many times smaller, which is what makes it emailable and web-usable.
- Batch conversion: Add several TIFFs and each is converted, returned together as a ZIP.
- Handles what browsers cannot: Since most browsers cannot display TIFF at all, decoding it with a purpose-built library is what makes this possible client-side.
- Converted privately: Both decode and encode happen in the tab from a library served on this domain, so a scanned document is never uploaded.
How to Use the TIFF to JPG Converter
- Add one or more .tif or .tiff files.
- Set the quality — 90 percent suits most scans.
- Press Convert Now.
- Download the JPG, or the ZIP for several.
How It Works
UTIF decodes the first image in the file to raw RGBA pixels, which are drawn to a canvas and encoded as JPG. Two behaviours follow from this that are worth knowing.
First, a multi-page TIFF — the kind a document scanner produces for a stack of pages, or a fax that ran to several sheets — yields only the first page. The remaining pages are decoded but not output, because a JPG holds a single image. For a multi-page scan you need a tool that produces a multi-page format such as PDF.
Second, TIFF is often used precisely because it is lossless, and JPG is not. Converting introduces JPEG compression, which is irreversible — you cannot later recover the TIFF's exact quality from the JPG. If the TIFF is an archival master, keep it and treat the JPG as a working copy for sharing rather than a replacement.
UTIF covers the common TIFF compression types, but the format is unusually varied and a few exotic or proprietary encodings may not decode. When that happens the tool falls back to the browser's own attempt, which occasionally succeeds where the library does not.
When You Need It
A conveyancing paralegal receives property deeds scanned as high-resolution TIFFs that are far too large to attach to an email to the client. Converting to JPG at high quality produces something sendable that is still perfectly readable. Deeds carry names, addresses and title numbers, so a conversion that runs on the firm's own machine rather than through an online service keeps client confidentiality intact.
A museum volunteer digitising a collection has master scans in TIFF for the archive but needs JPGs for the public-facing catalogue. Producing the web copies in the browser means the master files never leave the workstation, and the archival TIFFs stay untouched as the definitive record while the JPGs go online.
