Frequently Asked Questions
- Can I combine multiple TIFF files into one PDF?
- Yes. Upload several TIFF files at once and Convertify places each image on its own page in a single PDF, in upload order. A multi-page TIFF is also combined into one PDF with every page in sequence.
- Is TIFF to PDF conversion lossless?
- Not strictly. Each page is embedded as a high-quality JPEG at quality 95, which is visually very close to the original with only mild compression. It is high-quality rather than pixel-for-pixel lossless, so for normal viewing you will not see a difference.
- Will my converted PDF be searchable?
- No. A TIFF is an image, so converting it to PDF produces a page image with no text layer, which means the PDF is not searchable by default. To get searchable text, run OCR as a separate step with a dedicated tool.
- Does a multi-page TIFF keep all its pages in the PDF?
- Yes. Every page in the TIFF becomes a sequential page in the PDF. This is more reliable than opening the TIFF directly, since many basic viewers show only the first page of a multi-page TIFF.
- Can I choose the page size and orientation?
- Yes. Pick A4 or Letter for page size and portrait, landscape, or auto for orientation. Auto chooses portrait for taller images and landscape for wider ones. Each image is scaled to fit and centered with its aspect ratio preserved.
- Why does my converted page have a white background?
- Transparency in a TIFF is flattened onto a solid white background before the PDF page is written. This is intentional, so a transparent or partially transparent image looks like clean white paper rather than showing a dark or checkered area.
- What happens to a CMYK TIFF?
- The color is converted to sRGB so the PDF displays correct color on any screen. For professional print work that needs an exact CMYK profile with a specific rendering intent, handle that conversion in a dedicated prepress editor instead.
- Do I need to install any software?
- No. The converter runs in your browser on any device. There is nothing to install, and the resulting PDF opens in any browser, phone, or PDF reader without extra software.
- Can I convert scanned or fax TIFF images to PDF?
- Yes. Scans and fax-style TIFF images convert to PDF the same way as any other TIFF. This is one of the most common reasons to convert: it turns an archival scan into a document you can email, upload, or view anywhere.
- Is the converted PDF smaller than the TIFF?
- Usually yes. TIFF is often uncompressed or losslessly compressed and can be large, while the PDF embeds each page as a high-quality JPEG, which typically reduces size. The exact amount depends on the image content.
- Can Windows open TIFF files?
- Yes. Windows opens TIFF files in the Photos app and the legacy Windows Photo Viewer, and both can page through a multi-page TIFF. The issue is sharing: browsers and many other apps cannot display TIFF, so converting to PDF makes the document open reliably for everyone.
- Why will my browser not open a TIFF file?
- Most web browsers do not include a TIFF decoder, so a TIFF link usually downloads instead of displaying, or shows nothing. TIFF is a specialized imaging format rather than a web format. Converting to PDF fixes this, since every browser can display a PDF.
- Is TIFF or PDF better for archiving?
- They serve different archival roles. Uncompressed TIFF is a classic preservation master because it stores exact pixels, while PDF (and PDF/A) is the standard for a searchable, shareable document of record. A common practice is to keep the TIFF as the master and a PDF as the access copy.
- What is the difference between .tif and .tiff?
- There is none. Both extensions refer to the same Tagged Image File Format. The shorter .tif dates from older systems that limited extensions to three characters; the file contents are identical and both convert the same way.
- Can I pick which pages of a TIFF to include?
- Not yet. Convertify currently reads all pages of each TIFF and writes them to the PDF. Selecting specific pages to include is planned. For now, the full document is converted.
Why convert TIFF to PDF?
TIFF is built for capture and archiving, not for sharing. It preserves every pixel of a scan or fax, which makes files large and, more importantly, hard to open: most web browsers do not render TIFF at all, so a TIFF emailed to a colleague often will not preview and needs a dedicated image viewer. PDF solves this. As an ISO standard (ISO 32000) for documents, a PDF looks the same on every device and opens in any browser, phone, or email client without extra software.
Converting TIFF to PDF is about making an archival or scanned image usable: something you can attach to an email, upload to a portal, view on a phone, or hand to someone non-technical who just needs to read it. If you have a multi-page TIFF, PDF also keeps all pages together in one file that pages through cleanly, which many basic TIFF viewers fail to do.
What is a TIFF file?
TIFF (Tagged Image File Format) is a raster image format widely used for document scanning, archival preservation, medical and scientific imaging, publishing, and fax systems. Unlike JPEG, a TIFF is usually stored with lossless compression or no compression at all, so it preserves every pixel of the original. A single TIFF file can also hold multiple pages, which is why scanned multi-page documents are often saved as one .tif or .tiff file.
That fidelity is exactly why TIFF is awkward to share. The files are large, and because TIFF is a specialized imaging format rather than a document format, everyday software and web browsers often cannot display it. Converting to PDF keeps the visual content while wrapping it in a format built for viewing and sharing. If you need the reverse direction, see PDF to TIFF.
How Convertify converts .tif and .tiff to PDF
Both .tif and .tiff files convert the same way, since they are the same format with two spellings of the extension. Each page of your TIFF becomes one page in the PDF, in order. Convertify reads the image, fits it to your chosen page size, centers it, and preserves the aspect ratio so nothing is stretched. The page image is embedded at high quality, encoded as JPEG at quality 95, which is visually very close to the original with only mild compression. This is high-quality rather than strictly lossless: the difference is not visible in normal viewing, but the page is recompressed rather than stored pixel for pixel.
Color is converted to sRGB for universal display, so a TIFF in CMYK or another color space still shows correct colors on screens. Transparency is flattened onto a white background, so a transparent or partially transparent TIFF looks like a normal white document page rather than showing a dark or checkered backdrop.
Multi-page TIFF to one PDF
A single TIFF file can hold many pages, stored internally as a chain of images. The catch is that many everyday viewers, including some built-in operating system apps, show only the first page of a multi-page TIFF, so recipients can miss most of the document. Converting to PDF fixes this: every page in the TIFF is written as a sequential PDF page, and any PDF reader pages through the whole document.
You can also upload several separate TIFF files at once and get a single combined PDF, with each image placed on its own page in upload order. This is the simple way to merge a stack of scanned pages into one shareable file. Convertify reads all pages of each TIFF you provide; selecting specific pages to include is planned. To combine other image types into a PDF, see JPG to PDF, PNG to PDF, or Images to PDF.
Page size and orientation
You can choose the PDF page size and how each image sits on it. Page size options are A4 (210 by 297 mm, the international standard) and Letter (8.5 by 11 inches, common in North America). Orientation can be portrait, landscape, or auto.
Auto orientation looks at each image and picks portrait for taller images and landscape for wider ones, which is useful when a single TIFF mixes page shapes. Whatever you choose, each image is scaled to fit inside the page and centered, with its aspect ratio kept intact, so a wide scan is not squashed to fit a portrait page.
Transparency and color handling
TIFF can carry an alpha channel and can store color in spaces other than the sRGB that screens expect, including CMYK used for print. Both are handled automatically on conversion.
Transparency is flattened onto a solid white background before the page is written, which is why a converted page looks like clean white paper rather than showing a black or transparent area. Color is converted to sRGB so the PDF displays consistent color on any monitor. If your work is destined for professional printing and depends on an exact CMYK profile with a specific rendering intent, treat that as a prepress step in a dedicated editor, since faithful CMYK separations need a target ICC profile rather than a general-purpose screen conversion.
Should you convert, or keep the TIFF?
If you already have a TIFF, the question is whether to convert it or leave it as is. Convert to PDF when the file needs to travel: when you are emailing it, uploading it to a portal, viewing it on a phone, sending it to someone non-technical, or combining several scanned pages into one readable document. Those are the situations where TIFF gets in the way and PDF just works.
Keep the original TIFF when a specific system or standard asks for a pixel-exact image master, such as a preservation archive or an imaging workflow that requires the untouched scan. A practical habit is to hold onto the TIFF as your master copy and hand out a PDF as the everyday version. You are not losing the original by converting; you are creating a shareable companion to it. If you need a single image instead of a document, TIFF to JPG and TIFF to PNG export pages individually.
Searchable text and OCR
A TIFF is an image, so the text inside a scanned page is pixels, not characters. Converting to PDF places that image on the page but does not add a text layer, which means the resulting PDF is not searchable or selectable by default. This is true of any straight image-to-PDF conversion, not a Convertify limitation specifically.
If you need to search, copy, or index the text, run optical character recognition (OCR) as a separate step using a dedicated OCR tool. OCR reads the image and produces a hidden text layer over it. Convertify focuses on producing a faithful, shareable page image; pairing it with an OCR pass afterward gives you a searchable document when you need one.
File size and how to open the result
Converted PDFs are often smaller than the source TIFF, though the actual result depends on the image content and the compression used in the original TIFF. TIFF is frequently uncompressed or losslessly compressed and can be very large, while the PDF embeds each page as a high-quality JPEG, which usually reduces size while staying visually close to the original. One exception: a TIFF already stored as tightly compressed black-and-white (such as CCITT Group 4 fax scans) can be very small to begin with, so its PDF may end up similar or even larger. Treat any size change as approximate rather than a fixed figure.
The output opens anywhere a PDF does: drag it into any browser, open it on a phone, or use any PDF reader. There is no special viewer to install and no compatibility step, which is the whole point of converting away from TIFF. Everything runs in your browser session and files are not kept long-term on the server.
