About Converting JPG to TIFF
Print shops, scanning bureaus and archival systems frequently ask for TIFF, and this converter produces the plainest possible version of it: uncompressed RGB, where every pixel is stored as literal colour values with no compression layer in between. That predictability is precisely why prepress and preservation workflows favour the format.
It is worth being clear about what this conversion does and does not do. JPEG is a lossy format, and the detail it discarded when the file was first saved is gone permanently. Wrapping those pixels in TIFF preserves them faithfully but cannot reconstruct anything, so any compression artefacts already in the JPEG are carried through unchanged — in a file that will be considerably larger.
Common use cases
- Submitting a photograph to a printer or publisher whose specification names TIFF
- Ingesting images into a document management or archival system that only accepts TIFF
- Preparing photographic material for layout software in a prepress workflow
- Meeting an institutional or legal deposit requirement that mandates TIFF
- Feeding OCR or analysis software that reads TIFF and nothing else
Tips for best results
- The TIFF will be much larger than the JPG, often by a wide margin, because the output is uncompressed while JPEG is heavily compressed.
- Converting does not improve image quality. JPEG artefacts already baked into the source are preserved exactly; TIFF cannot restore detail that was discarded at the original save.
- Always convert from the highest-quality JPG you have rather than from a copy that has been re-saved several times.
- The output is RGB. If your printer requested CMYK, perform that colour separation in colour-managed design software with the correct press profile.
- The result is a single-page TIFF, not the multi-page variety produced by fax and document scanning systems.
How to Convert JPG to TIFF Online
Turning a JPG file into TIFF is straightforward here — upload, convert, download. The key change: TIFF stores data losslessly, so the conversion introduces no new compression artifacts.
Drag and drop your file into the upload area, click to browse your device, or paste a URL to a file hosted online. You can upload files up to 250 MB and batch convert up to 20 files at once.
Once uploaded, the conversion from JPG to TIFF starts automatically. The process runs entirely in an isolated environment - your data never leaves the secure pipeline.
Your converted file is ready instantly. Click the download button to save it to your device. The file is deleted from memory immediately after download.
A more private way to convert JPG files
Plenty of sites convert JPG files. Very few promise never to keep them — PrivConvert does, and backs it up with how the service is built.
Every conversion runs in its own locked-down process with no network access, so files can never leak or interfere with one another.
Your files are handled entirely by automated code. No staff, partner or AI model ever reads, stores or trains on your data.
Files are processed in volatile memory (RAM) and purged the instant your download is ready — nothing is ever written to disk, cached or backed up.
Every upload and download is protected with TLS 1.3, so your image cannot be intercepted on the way to the server or back to you.
