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.

1
Upload your JPG file

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.

2
Automatic conversion

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.

3
Download your TIFF file

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.

Isolated sandbox

Every conversion runs in its own locked-down process with no network access, so files can never leak or interfere with one another.

No human ever sees it

Your files are handled entirely by automated code. No staff, partner or AI model ever reads, stores or trains on your data.

Zero data retention

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.

Encrypted transfers

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.

Frequently Asked Questions

Can I convert several JPGs at once?
Yes. Drop up to 20 JPG files into the upload area and each one is converted to TIFF in a single batch.
Is there a file size limit?
You can convert files up to 250 MB each. Because the TIFF output is uncompressed, expect the result to be considerably larger than the JPG.
Is it private?
Yes. Conversion runs entirely in memory - your images are never written to disk, never stored and are deleted the moment your download is ready.
Will converting to TIFF improve my image quality?
No. TIFF stores the pixels it is given without loss, but it cannot recover detail that JPEG discarded when the file was originally compressed. The conversion preserves quality; it does not add any.
Why is the TIFF so much bigger?
The output is uncompressed by design, storing every pixel as raw colour data, whereas JPEG compresses aggressively. A large increase in file size is expected and is what archival and print workflows want.
Can I get a CMYK TIFF?
Not from this tool, which produces RGB. Converting to CMYK correctly requires a colour-managed workflow with the specific ICC profile your printer uses, which belongs in design software.
Is this a multi-page TIFF?
No. Each conversion produces a single-page TIFF containing your one image. Multi-page TIFF is a different structure, typically generated by document scanners.
