TIFF to PDF

Combine supported TIFF and TIF scans into one image-based PDF. Every page in a multipage scan appears in order, with a thumbnail to check orientation before you create the file.

Choose files

Your TIFF files stay on this device. Preview and conversion run in browser workers without uploading or logging scan contents.

How it works

Choose one or more TIFF or TIF scans. The tool checks all pages before conversion.
Review the thumbnails. Move files up or down to change their order; pages within each file keep their original sequence.
Choose A4, Letter or image-sized pages. Image-sized pages use the scan's supported density metadata, with 96 DPI as the fallback.
Convert the scans, then download or share the complete PDF.

Single-page and multipage scan order

Every main image directory in a supported multipage TIFF becomes one PDF page. For example, a three-page TIFF followed by a two-page TIFF produces five PDF pages. Moving the files swaps those groups; individual frames are not reordered. Conversion fails if any page is unsupported or corrupt, so you do not receive an apparently successful PDF with missing scans.

Supported TIFF encodings

Classic little-endian and big-endian TIFF scans are supported when they use strips and 1-bit bilevel or 8-bit grayscale, RGB or palette data. Supported compression includes uncompressed, CCITT Group 3 and Group 4 fax scans, LZW, PackBits and Deflate. JPEG-compressed grayscale/RGB/YCbCr strips must contain valid bounded JPEG data with supported tables. All eight standard TIFF orientations are applied. BigTIFF, tiled images, separate color planes, CMYK/RAW, higher bit depths, alpha channels, document color profiles and old or unsupported JPEG variants are rejected with a clear message.

Paper size and scan density

A4 and Letter pages fit the scan proportionally inside a 24-point margin and use landscape paper when its physical image dimensions are wider than tall. Image-sized pages use pixels × 72 ÷ DPI for each dimension: a 1200 × 1800 scan at 300 DPI becomes 288 × 432 PDF points, or 4 × 6 inches. Missing or unitless density defaults to 96 DPI. Changing paper size does not add pixels or improve scan detail.

Limits that protect your device

Processing runs one page at a time, with input, page, per-frame pixel, total pixel and retained-output budgets. Smaller or low-memory devices use tighter limits. The initial decoder supports at most 4096 strips per image and rejects unusual structures rather than guessing. Split a large scan into smaller files when a limit is reached. Preview checks every supported page; OCR, PDF/A certification and embedded TIFF metadata are not included.

Frequently asked questions

Will every page in a multipage TIFF be included?

Yes, every supported main image directory is included in order. If one page is unsupported or corrupt, the whole conversion stops with an error instead of dropping that page.

Are TIF and TIFF different formats?

They are two filename extensions for the same format. Both work when the file uses a supported TIFF encoding.

Is the PDF searchable?

No. TIFF scans become PDF images. The tool does not recognize text or add an OCR layer.

Which fax and scanner compressions work?

Supported strip-based scans include CCITT Group 3/4, LZW, PackBits, Deflate and uncompressed images. Supported JPEG strips are also accepted. Unsupported bit depths, color models or layouts are reported before output is returned.

Does my scan get uploaded?

No. Parsing, preview and conversion run on this device in browser workers. Your scan contents and filenames are not sent to a server.
