JPEG to TIFF converter

JPG to TIFF moves a decoded JPEG photo into a TIFF container, often increasing size without recovering detail lost by JPEG.

What you get — and what changes

  • Dimensions Kept

    The 640×480 JPEG wrote a 640×480 TIFF, so no resize happened with default options.

  • File size Changed

    The 13,991 byte source expanded to a 234,942 byte TIFF using tiff_adobe_deflate compression.

  • Color mode Kept

    The output opened as RGB TIFF, matching the decoded JPEG color mode from the source photo.

  • JPEG artifacts Kept

    Block noise and softened detail already in the JPEG are stored faithfully inside the TIFF pixels.

  • Transparency Lost

    A JPEG source has no alpha channel, so the TIFF output remains fully opaque RGB imagery.

  • Resolution metadata Changed

    The inspected TIFF reported 1×1 dpi, so this conversion should not be used to assert scan resolution.

Sample conversions

Photo-style JPEG

Input
13,991 byte JPG at 640×480 with a gradient background and a white label drawn into the pixels.
Output
234,942 byte TIFF at 640×480, RGB, tiff_adobe_deflate. The file was much larger and kept JPEG-era artifacts.

JPEG accepted by a TIFF-only archive slot

Input
A flattened JPEG scan with no transparency and no need for camera metadata preservation.
Output
One RGB TIFF frame. It met the container requirement, but it did not become a higher-quality scan source.

A real JPEG → TIFF run

We converted our JPEG sample (42 KB) with Image engine on 2026-10-20. It took 43 ms and produced a 145 KB TIFF file, 3.4× larger than the input. The engine raised 1 warning, listed below.

Is your file a scan?

JPG to TIFF does not make a photographed page searchable. Use Deep Read or OCR before relying on text inside the converted TIFF.

Options and when to change them

width
Downsize the JPEG before TIFF output if the receiving system rejects large pixel dimensions.
height
Set height with width only for an exact raster box; otherwise preserve the photo ratio.
fit
Use cover for cropped thumbnails and contain when padding is preferable to losing photo edges.

Do it yourself

ImageMagick 7

bash
magick photo.jpg -compress Zip photo.tiff

The command changes the container and compression method, not the damage already introduced by JPEG encoding.

JPEG to TIFF by API or MCP

The HTTP API and the MCP server run the exact engine this page uses (Image engine); the response carries the same warnings the web converter shows. Check support first with GET /api/v1/pairs?from=jpg&to=tiff.

curl
curl -X POST https://filetypeconverters.com/api/v1/convert \
  -H "Authorization: Bearer $FTC_API_KEY" \
  -F "file=@input.jpg" -F "from=jpg" -F "to=tiff" \
  -F 'options={"dpi":96}' \
  --output output.tif

When this is the wrong conversion

  • Use the original camera RAW, PNG, or TIFF if the goal is better image quality than the JPEG copy.
  • Use /convert/jpg-to-png when a PNG-only editor is the target and TIFF is not required.
  • Keep JPG for normal web sharing because TIFF will usually be larger and less browser-friendly.

JPEG to TIFF questions

Does JPG to TIFF improve image quality?

No. It stores the decoded JPEG pixels in TIFF, including artifacts and blur that were already present.

Why did the TIFF get so large?

TIFF deflate stores RGB pixels differently from JPEG's lossy photo compression. Our 13,991 byte JPG became 234,942 bytes.

Can JPG to TIFF add transparency?

No. JPEG starts opaque, and the tested TIFF output opened as RGB with no alpha channel.
