Check which page is being exported
The TIFF to PNG/JPG tool decodes the first readable page and creates one still output. A multi-page source is not split into all its pages. The result shows a warning when extra pages exist, and the original remains unchanged. If page two contains the important information, a first-page export does not satisfy the request.
Use a workflow that explicitly extracts every page when a submission requires the complete scan. A ZIP of several first-page outputs from several TIFF files is not a complete export of every page within those files. Tool Fera describes this distinction near the controls rather than implying multi-page preservation from a general TIFF support label.
A browser-rendered copy has different color data
This workflow turns supported TIFF pixels into an 8-bit RGBA browser image. Higher bit depth, original ICC profiles, specialized channels and camera metadata are not retained. A delivery preview may therefore look different from a managed imaging application even when width and height remain the same. Keep the original TIFF for further imaging, print production or archival needs.
Choose PNG for a lossless copy of the decoded pixels, including supported transparency, or JPG for an opaque photographic delivery copy. JPG applies another lossy encoding and fills transparent areas with a selected color. Neither output recreates high-bit-depth source data after the browser has rendered it. Confirm the recipient’s color and format requirements instead of relying on the extension.
Creating TIFF does not create missing detail
The PNG/JPG to TIFF tool writes a genuine single-page, uncompressed 8-bit RGBA TIFF. Alpha is explicitly tagged as unassociated so readers can interpret transparent edges correctly. It is not a layered file, a multi-page scan or a CMYK separation. The output can be much larger than a compressed JPG or PNG with the same dimensions.
Converting a small JPEG photograph to TIFF does not recover detail discarded by JPEG compression. It also does not establish a print density, repair blur or restore camera metadata. Use TIFF output because the destination accepts this specific variant, then check it there. If the recipient requests a different TIFF compression, bit depth or channel arrangement, another imaging workflow is required.
Plan for decoded pixels as well as file bytes
A compressed TIFF can be small on disk yet require a large decoded pixel buffer. Browser memory limits are especially important on phones. Tool Fera limits general decoded inputs to 20 million pixels, with a smaller 8 million-pixel limit for uncompressed TIFF output. Optional maximum width can reduce the output deliberately, but it cannot make an oversized source safe before decoding.
Batches are processed one image at a time, with individual errors and a combined result-size limit. A corrupt page or unsupported variant does not cancel the other files. Output dimensions and actual bytes are shown before download. Use Image Resizer or a source imaging application when a large file needs a smaller pixel grid, and retain the original before doing so.
Verify the saved delivery copy
Open the actual downloaded file rather than only checking a preview. Confirm the intended page, readable text, dimensions, colors and transparent edges where relevant. For a multi-page source, explicitly acknowledge that the sharing copy contains only its first page. If the recipient requires the whole scan, return to a multi-page extraction or document workflow before submitting it.
Independent TIFF decoding can confirm a valid output and its dimensions, but that does not guarantee compatibility with every scanner, printer or archival system. Read the destination’s requirements for single versus multi-page files, color depth and compression. A successful conversion is a useful delivery operation with known limits, not proof that every property of the original has survived.
Treat TIFF conversion as a specific delivery operation. Tool Fera reads the first page and can write one uncompressed RGBA page, while profiles, high bit depth and extra pages remain outside this workflow. Keep the original and verify the saved copy in the destination.
