Before converting a scanned packet, count its pages. A preview that shows the first sheet can look successful while omitting the rest of the document.
Choose the result the reader needs
For a single scanned diagram, export a PNG or another suitable browser image from an image application. Retain enough detail for the labels to be read at their intended size. Keep the TIFF as the source, particularly when it carries printing or archival information.
For a packet, export each page and keep its order. Use filenames such as inspection-01.png and inspection-02.png, then compare them with the source packet. Do not assume changing .tif to .png converts the contents.
TIFF can contain multiple images and use different compression and color formats. Support for one file does not prove support for every TIFF your scanner produces. Even a reader that recognizes the container may expose only its first image. That is why page-count reconciliation belongs before the layout check.
Add the converted pages to HTML
This illustrative fragment assumes that two PNG files have already been exported into the same folder as the page:
<h1>Equipment inspection scan</h1>
<figure>
<img src="inspection-01.png" alt="Inspection record, page 1">
<figcaption>Page 1 of 2</figcaption>
</figure>
<figure>
<img src="inspection-02.png" alt="Inspection record, page 2">
<figcaption>Page 2 of 2</figcaption>
</figure>
<p><a href="inspection.tiff">Original TIFF scan</a></p>
Add this rule to the page's stylesheet so each image can shrink to fit its container without stretching its proportions:
figure img { max-width: 100%; height: auto; }
If the scan contains instructions people must follow, provide those instructions as readable text too. Page labels alone do not describe a diagram or make scanned words searchable.
The HTML does not perform a conversion, and its original-file link may open a viewer or download the file depending on the reader's environment. Image path troubleshooting helps when a converted image still fails to load.
When direct TIFF decoding is required
A browser decoder is useful when an application must accept TIFF uploads without a separate export step. Check its documented compression support, multipage behavior, file-size handling, and failure reporting before choosing it.
Prepare a small acceptance set from the scanners you actually use. Include a single-page file and a multipage file. Confirm the reported page count, each page's orientation, and readable content. A canvas showing page one is insufficient evidence for a packet viewer.
Do not claim a conversion preserves every property of the original. Browser images are reading copies; the TIFF can retain a role that a display image does not.
Finish with a page-by-page check
Open the HTML in the browsers your readers use. Inspect every exported page, follow the original-file link, and check that fine labels are legible when enlarged. Keep the source and viewing copies together in your records, and name the viewing set so someone can trace it back to the correct scan.
