Convert TIFF to PDF

Turn TIFF scans into a PDF in your browser: one page per file, A4 or Letter, optional size reduction. Nothing is uploaded.

Convert TIFF to PDF: what to know

Scanners, fax software and document management exports still produce TIFF, and almost every place that wants a scanned document — banks, universities, tax portals, courts — wants it as a PDF. This page decodes TIFF files on your device and writes them into a PDF, one page per file, in the order you choose, without uploading anything.

How to convert TIFF to PDF

Drop the .tif or .tiff files above (a small decoder is fetched the first time). Order them with the arrows, or Sort by name for scanner output numbered page-001, page-002 and so on. Choose A4 or US Letter for a printable document, or Fit to image to keep each page at the scan's own size, then click Create PDF. Up to 20 files of 20 MB each per batch; re-save very large uncompressed scans with LZW compression first.

How the scan is stored in the PDF

PDF cannot hold TIFF data directly, so each file is decoded and stored as a high-quality JPG (quality 92) inside the document — or as lossless PNG-style pixels when the TIFF has transparency. At quality 92 text scans stay clean and the page is the full resolution of the scan. Bilevel fax TIFFs become grayscale pages; they are small either way.

Multi-page TIFF files contribute their first page. For a multi-page fax or scanner file, export it as one TIFF per page (most scanner software has an option for that) and add all of them here; combine is on by default, so they become one PDF.

Keeping the PDF small enough to send

A 300 dpi A4 colour scan is 25 MB as an uncompressed TIFF and about 1 MB as a JPG page, so a ten-page document lands near 10 MB. Reduce file size caps each page at 2480 pixels on the long side (exactly 300 dpi on A4) and uses JPG quality 80, which usually halves that again with no visible change on paper. For grayscale text scans, converting the TIFFs to JPG first in the converter and sending the results here gives the smallest files.

Supported TIFF files

Uncompressed, LZW, PackBits and Deflate compression, RGB, grayscale, palette and bilevel images, both byte orders. JPEG-in-TIFF and some CMYK variants are rejected with a clear message; re-saving as LZW TIFF fixes them. The 40-megapixel limit applies per file. Resolution tags in the TIFF are not used for the page size — choose A4/Letter for a standard page, which scales the scan to fit.

Questions about TIFF to PDF

Is the scan uploaded?
No. Decoding and PDF creation run in your browser; only the decoder code is downloaded.
Can I combine many TIFF scans into one PDF?
Yes — up to 20 files per batch, ordered with the arrows or Sort by name.
What happens to multi-page TIFFs?
The first page is used. Export one TIFF per page from your scanner for a complete document.
Does it keep the scan resolution?
Yes unless Reduce file size is on; the full pixels are stored, and A4/Letter pages scale them to fit the page.

How to make a PDF from images

  1. Add up to 20 images — JPG, PNG, WebP, HEIC, AVIF, GIF, BMP, SVG, ICO or TIFF. They stay in your browser.
  2. Put them in order with the arrows (or Sort by name), then choose Fit to image for screen use or A4 / US Letter for a printable document.
  3. Click Create PDF and download the file — or send it to PDF to Image, or keep one PDF per image by turning off Combine.

JPG and PNG files are embedded exactly as they are, so nothing is re-compressed unless you turn on Reduce file size. HEIC, WebP, AVIF, GIF, BMP, SVG, ICO and TIFF are decoded first and stored as JPG (or PNG when transparent).

Useful details

Are my images uploaded?

No. The PDF is written in your browser and the images never leave your device. Keep the tab open until you download or send the result — reloading clears the batch. Website hosting and performance measurement are described in our Privacy notice.

Which images can I use?

JPG, PNG, WebP, HEIC/HEIF (iPhone photos), AVIF, GIF, BMP, SVG, ICO and TIFF, up to 20 files, 20 MB each and 100 MB per batch, at most 40 megapixels each. Animated files contribute their first frame. PDFs are not accepted here — use PDF to Image for those.

Does converting lower the quality?

Not for JPG and PNG: their bytes are placed in the PDF unchanged. Other formats are decoded and stored as JPG at quality 92 (or lossless PNG when transparent), which is visually identical. Reduce file size is the only setting that trades quality for size, and it is off by default.

How do I keep the PDF small?

Turn on Reduce file size: every image becomes a JPG at quality 80 with the long side capped at 2480 pixels — about 300 dpi on A4 — which typically shrinks phone photos six to eight times. For an exact budget, compress the images first with a target size and send the results here.

What do Fit to image, A4 and US Letter mean?

Fit to image makes each page exactly the size of its image, so nothing is scaled or padded. A4 and US Letter make standard printable pages; each image is scaled to fit inside the margins and centred. Auto orientation turns wide images onto landscape pages.

Why did my sideways phone photo come out upright?

Phones store many photos rotated with an orientation flag. Toolkitta reads the flag and rotates those photos before placing them, so the PDF shows them the way your phone does. The file details say how many photos were rotated.

Is metadata copied into the PDF?

No. EXIF data such as camera settings and GPS location is not written into the document; only the picture is. The PDF's own properties list Toolkitta as the producer and the creation time.

How do I continue in another tool?

Use Send to under the finished PDF to open PDF to Image with it loaded, or start from the compressor, cropper or converter and use Send to → Image to PDF from their results.
