Merge TIF to PDF

How to Merge TIF to PDF Online

1. Upload Your TIF Files: Drag and drop, or click "+ Add Files" to select multiple .tif or .tiff images. Both extensions are accepted — they are the same format. Drag rows in the file list to set page order in the output PDF.
2. Pick Combine Mode: Default is "Single PDF" (one combined document, one page per TIF). Switch to "Individual PDFs" to wrap each input TIF as its own one-page (or multi-page) PDF in a single batch.
3. Set Page Layout (Optional): Page layout defaults to Portrait — switch to Landscape for ledger drawings, plats, or wide spreadsheets. Paper size defaults to A4; pick LETTER, LEGAL, TABLOID, A3, ARCH A/B, or "Original" (matches the source pixel dimensions). Image placement: "Contained" (default, fits inside margins) or "Cover" (fills page edge-to-edge — best for raw scans). Image alignment Top/Center/Bottom and Margin from "No margin (0")" up to "Large (2x1")" round out the layout controls.
4. Tune Compression and Merge: Image Quality defaults to 75% — push to 85-95 for archival scans, drop to 50-60 to shrink large multi-page batches. Compression Type defaults to "Screen (Best)" for smallest output; pick Ebook, Default, Prepress, or Printer for higher print fidelity. Click "Merge" — files process in your browser session, no sign-up, no watermark.

Why Merge TIF to PDF?

TIF (and the equivalent .tiff) is the Tagged Image File Format, created by Aldus in 1986 and now maintained by Adobe since the 1994 Aldus acquisition. The TIFF 6.0 spec (June 1992) is still the working baseline, with multi-page support originally designed for telefax and now the default container for office scanners, document-imaging systems, and archival workflows. The 8.3 filename limit on early FAT filesystems is why you see two extensions — .tif had to fit in three characters, .tiff appeared once long filenames became standard. They open in identical applications.

PDF is the better delivery wrapper. It embeds all pages in one file, renders identically across every viewer, supports text overlays via OCR, and is accepted by every email gateway, court e-filing system, and DMS. Common reasons to merge:

• Office scan batches — Production scanners (Fujitsu fi-series, Canon DR-series, Kodak i-series) frequently output one TIF per page when set to "single-page" mode. Combine the page-001.tif…page-NNN.tif sequence into a single PDF for filing.
• Multi-page fax archives — Group 3 and Group 4 fax compression are core TIFF compressions; old fax servers and MFP fax modules drop messages into network folders as TIFs. PDF makes those archives searchable and emailable.
• Legal e-filing — Most US federal courts (CM/ECF) and many state portals require PDF, not TIFF. Counsel scanning exhibits to TIF for archival fidelity then merges to PDF for filing.
• Medical imaging exports — Diagnostic equipment and PACS exports often write TIFF for lossless storage. Merging exam pages to a single PDF makes referrals and patient-record requests one-click.
• Architectural and engineering drawings — Plotters and large-format scanners use TIFF (often with LZW compression) for line-art clarity. ARCH A/B page sizes plus Landscape layout produce a tidy multi-sheet drawing set.
• GIS, satellite, and cartography — GeoTIFF imagery and historical map scans archive as TIFF; merging selected sheets into a PDF produces a portable atlas without losing the source TIFFs.

Frequently Asked Questions

Is .tif different from .tiff?

No. Both extensions point at the Tagged Image File Format. The shorter .tif exists because early FAT/DOS filesystems used the 8.3 filename convention and only allowed three-character extensions. Once long filenames became standard with NTFS, HFS+, and ext, .tiff could be written in full. Every TIFF-aware application reads both, and renaming .tif to .tiff (or vice versa) does nothing to the bytes inside. This tool accepts both interchangeably in the same batch.

My scanner produced one TIF per page — can I combine them in upload order?

Yes. Upload all of them, then drag rows in the file list to set the page order before clicking Merge. Most scanners name files sequentially (scan_0001.tif, scan_0002.tif, …) so a default name-sort already produces correct order. With "Single PDF" selected (the default), each TIF becomes one PDF page in that order.

What about a multi-page TIF file — do all pages get included?

Yes. Multi-page TIFFs are a native part of the TIFF spec (originally designed for telefaxes per the Adobe-maintained TIFF 6.0 standard). When you upload a multi-page TIF, every page inside it becomes a corresponding PDF page in the output. Combine that with several single-page TIFs in the same batch and they are all flattened into the merged PDF in upload order.

Should I pick "Cover" or "Contained" placement?

"Cover" fills the entire page edge to edge — best when the TIF is already a clean scan of a whole document and you want zero margins, like reproducing a faxed memo or court exhibit. "Contained" (default) shrinks the image to fit inside the chosen margin — better when the source aspect ratio doesn't match the chosen paper size, or when you want consistent white borders for a binder-ready set. With "Cover," set Margin to "No margin (0")"; with "Contained," Narrow or Normal margins look most professional.

Why is my merged PDF so much larger than the source TIFs?

TIFF often uses lossless compression (LZW or CCITT Group 4 for B&W documents) which is very efficient on text and line art. PDF embeds the image stream and applies its own compression based on the chosen profile. If you picked "Prepress" or "Printer," every image is preserved at high quality and the PDF will be larger. Switch Compression Type to "Screen (Best)" and drop Image Quality to 60-70% to shrink the output significantly — for searchable office documents the difference is rarely visible.

How do I keep architectural drawings sharp at full size?

Set Paper size to ARCH A, ARCH B, A3, or TABLOID; Page layout to Landscape; Image placement to "Contained" with Narrow margin; Compression Type to "Prepress" or "Printer"; and Image Quality to 90-100%. ARCH A is 9x12 inches and ARCH B is 12x18 inches — common working sizes for plan sheets. The original TIFF's pixel dimensions stay intact through the merge; the PDF page just gives the viewer the right physical scale.

Can I get one PDF per TIF instead of merging everything?

Yes. Switch the Combine? control from "Single PDF" to "Individual PDFs." Each input TIF becomes its own PDF (a multi-page TIF becomes a multi-page PDF). The output is delivered as a batch, which is useful when you need a hundred separate filings instead of one combined document.

Does the tool preserve color profiles and transparency?

Color is preserved through the compression profile you choose — Prepress and Printer keep the wider color range, while Screen and Ebook downsample for size. The Image Transparency control defaults to "Unchanged"; switch to "Removed" if a TIFF with an alpha channel is rendering with unwanted transparent regions in your PDF viewer (some viewers flatten alpha against black instead of white).

Is there a file size or page count limit?

Files are processed in your browser session — no upload to a third-party server, no watermark, no sign-up. Practical limits come from your device's RAM rather than a server-side cap; modern laptops handle a 200-300 page merge of standard-DPI document scans without issue. For very large jobs, run the TIFF compressor first, or merge in two batches and combine the resulting PDFs with PDF compress.

How does this compare to converting one TIF to PDF?

Use Convert TIF to PDF for a single-file conversion. This Merge tool is built for batches — multi-file ordering, single-output combination, and per-page layout control. The reverse direction (PDF page extraction back to TIFF) is a different workflow; for cousin formats see Merge JPG to PDF and Merge PNG to PDF.
