TIFF to PDF
Convert TIFF scans and archival images into a PDF.
TIFF or TIF · or drag and drop · max 50 MB each
TIFF to PDF converts TIFF image files into PDF documents directly in your browser. TIFF (Tagged Image File Format) is the standard format for scanned documents in professional, medical, legal, and archival contexts — most high-quality document scanners produce TIFF output, and many document management systems store scanned originals as TIFF for its lossless quality. However, TIFF is poorly supported outside of specialist software — browsers won't open it, most email clients won't preview it, and most document portals won't accept it. Converting to PDF gives you a format that's universally readable, emailable, printable, and accepted everywhere. iSavePDF's TIFF to PDF tool runs entirely in your browser using pdf-lib — your file is never uploaded to a server. The tool is free with no account required and no watermark on the output.
Step by step
How to tiff to pdf on iSavePDF
Open TIFF to PDF on iSavePDF
Visit isavepdf.com/tiff-to-pdf in any modern browser — Chrome, Edge, Safari, Firefox, or Brave on desktop or mobile. No plugin, extension, or app installation is needed. The tool loads directly in your browser.
Upload your TIFF files
Drag one or more TIFF files (or TIF files — both extensions are the same format) onto the upload zone, or click to browse your device. Each file can be up to 50 MB. Multi-page TIFFs are supported — a single TIFF file containing multiple pages will have each page placed onto its own PDF page.
Arrange the order if needed
If you uploaded multiple TIFF files, drag the thumbnail previews to set the page sequence in the output PDF. For a multi-page TIFF, the internal page order of the TIFF is preserved automatically.
Convert
Click Convert. pdf-lib reads each TIFF (or TIFF page) and places it onto a PDF page sized to the image's natural dimensions. Everything runs locally in your browser. A typical scanned TIFF page converts in under a second; a multi-page TIFF or large batch takes a few seconds more.
Download the PDF
Click the download button to save your PDF. To confirm no file was transmitted during conversion, open browser DevTools, switch to the Network tab, and re-run the process — you'll see no outbound file transfer requests.
How it works
How TIFF to PDF works
Drop your TIFF files
Add .tif or .tiff scans from your scanner, medical imaging tool, or archival library.
Reorder if needed
Set the page order using the up/down arrows on each thumbnail.
Download the PDF
TIFFs are decoded, lightly compressed, and embedded as PNG in the PDF for lossless quality.
When to use it
Common use cases
Converting scanned documents for submission and sharing
Professional document scanners — the kind found in law offices, hospitals, accounting firms, and government agencies — default to TIFF because it preserves full scanning quality without compression artefacts. But the documents scanned this way (contracts, medical records, legal filings, financial statements) almost always need to be shared or submitted somewhere that only accepts PDF. Converting locally means these sensitive documents don't need to pass through a third-party conversion service before you can submit them.
Archiving scanned multi-page documents
Multi-page TIFF files are a common output from batch document scanning — a stack of documents fed through an automatic document feeder produces a single TIFF file containing all the scanned pages. Converting this to a multi-page PDF makes it easier to navigate, annotate in PDF readers, index in document management systems, and read on any device. PDF is also better supported in long-term archiving systems than TIFF, despite TIFF's theoretical archival advantages.
Medical and healthcare imaging workflows
Clinical documents, lab reports, pathology slides, and referral letters are frequently scanned as TIFF in healthcare environments. Sharing these with patients, other clinicians, or insurers typically requires a format they can open without specialist software — PDF fills that role. Converting TIFF medical documents to PDF locally is important because this content is protected health information that should not be transmitted through unvetted services.
Reducing file sizes for storage and email
TIFF files scanned at high resolution can be enormous — a single A4 page at 600 DPI in TIFF is often 20–50 MB. PDF applies compression during creation and typically reduces this to a fraction of the original size while maintaining the visual quality needed for reading and printing. For very large TIFF files, running the output through iSavePDF's Compress PDF tool after conversion can reduce the size further.
Why iSavePDF
The privacy-first way to tiff to pdf
TIFF files frequently contain sensitive content — that's precisely the context in which TIFF is most commonly used. Medical records, scanned legal documents, archived financial records, and identity document scans are all routine TIFF use cases. Sending these through an online conversion service means the file travels to a server you don't control, is processed in an environment you can't inspect, and may be retained beyond the stated deletion window. For content that falls under HIPAA, GDPR, legal privilege, or standard professional confidentiality obligations, that risk is not acceptable.
iSavePDF converts TIFF to PDF entirely in your browser using pdf-lib. Your file is read from your device into browser memory, processed locally, and saved to your downloads folder. Nothing leaves your device during the conversion. You can confirm this using browser DevTools — open the Network tab, run a conversion, and observe that no file transfer occurs. The tool is free and supported by display advertising. We have no infrastructure to receive, process, or store user files, because none exists.
Tips & limits
Tips for the best results
Multi-page TIFFs are fully supported
TIFF supports storing multiple pages (called 'strips' or 'pages') in a single file. When you upload a multi-page TIFF, each page is placed onto its own PDF page in the output, preserving the original order. You don't need to split the TIFF into individual files first.
TIFF compression types are handled automatically
TIFF files can use different internal compression schemes — LZW, CCITT (for fax-style black-and-white documents), PackBits, uncompressed, and others. The tool handles these transparently. You don't need to decompress or re-save the TIFF before uploading.
For very large TIFFs, compress the output PDF
When a high-resolution TIFF is placed into a PDF, the output can still be large if the image data isn't heavily compressed. After conversion, run the PDF through iSavePDF's Compress PDF tool to reduce the file size for sharing or email.
TIFF vs PNG for archiving
TIFF is often preferred in archival contexts because it's well-understood and widely used in professional scanning workflows. But for long-term digital preservation, PDF/A (a standardised archival PDF variant) is increasingly the preferred format. The PDF output from this tool is a standard PDF — converting to PDF/A requires a separate step with specialist software if your archiving requirements specifically mandate it.
