Supports: TIFF, TIF
.tif and .tiff (they are the same format — .tif is the legacy 8.3 short name). Multi-page TIFFs and batches are supported — drop in several scans and each one converts in parallel.TIFF (Tagged Image File Format) was created by Aldus Corporation in 1986 for desktop publishing; Adobe acquired Aldus in 1994 and still holds the copyright. The spec has had no major revision since 6.0, published June 3, 1992 — which is part of why it's so dependable: a TIFF written 30 years ago still opens today. It's a flexible container that can be uncompressed or compressed losslessly (LZW, PackBits, ZIP/Deflate), carries 1-bit, 8-bit, or 16-bit-per-channel data in RGB, CMYK, or grayscale, stores multiple pages in one file, and preserves every pixel. That makes it the default for scanning, archival, fax, professional photography, and print — but also makes the files large and awkward for everyday use.
That size and the format's print-shop lineage are exactly why people convert away from TIFF:
| Format | Compression | Transparency | Typical size vs TIFF | Best for |
|---|---|---|---|---|
| TIFF | Lossless or none (LZW, ZIP, PackBits) | Yes (alpha) | 1× (baseline, often large) | Archival, scanning, print, 16-bit editing |
| JPG | Lossy | No | ~5–20% | Photos for web, email, social |
| PNG | Lossless | Yes (alpha) | ~30–80% | Lossless web graphics, screenshots, transparency |
| WebP | Lossy or lossless | Yes (alpha) | ~5–40% | Modern web delivery at small size |
| AVIF | Lossy or lossless | Yes (alpha) | ~3–25% | Smallest high-quality web images |
| Per-page (varies) | No (page background) | Varies | Sharing multi-page scans and documents |
There is none — .tif and .tiff are two extensions for the exact same format. The three-letter .tif survives from the old MS-DOS 8.3 filename limit, while .tiff is the longer modern spelling. Both use the same internal structure and the same image/tiff MIME type, so any tool that reads one reads the other. This converter accepts both, and you can output to either by picking TIF or TIFF in the format dropdown.
It can be, and almost always is in practice. TIFF is a container that supports several compression schemes: no compression at all, the lossless LZW, PackBits, and ZIP/Deflate methods, and — less commonly — lossy JPEG-in-TIFF. The vast majority of TIFFs from scanners, cameras, and editing software are stored uncompressed or with lossless LZW/ZIP, which is why TIFF is trusted for archival and print masters. When you convert TIFF to JPG, AVIF, or a lossy WebP, that's where compression loss is introduced — by the target format, not by the TIFF.
Some, because JPG is a lossy format — it discards fine detail to reach its small size, and that loss is permanent. For most web and email use the difference is invisible at the "Very High" quality preset, and the size savings are dramatic (a 30 MB scan can become well under 1 MB). If you need to preserve every pixel, convert to PNG or lossless WebP instead, which keep TIFF's full detail while still opening in a browser. Pick the target based on whether small size or perfect fidelity matters more for that file.
Yes. TIFF can store multiple images (the spec calls them subfiles) in a single file, which is common for scanned multi-page documents and faxes. Converting a multi-page TIFF to PDF is the most natural choice — it keeps all the pages together in one shareable document. Converting to a single-frame image format like JPG or PNG will typically output the first page or one image per page depending on the file; use TIFF to PDF when you want the whole stack preserved as a document.
Match it to your source and destination. 8-bit (Recommended) covers virtually all web and everyday output — JPG, standard PNG, and WebP are all effectively 8-bit per channel. Choose 16-bit (High Precision) only when your TIFF holds 16-bit data (high-end photo edits, medical or scientific scans) and your target format can carry it, since most web formats will discard the extra precision anyway. 1-bit (Black & White) is for pure bilevel content like scanned line art or fax pages, where it produces the smallest possible file.
Because TIFF preserves every pixel and is usually stored uncompressed or with lossless compression, while JPG throws away detail your eye is least likely to notice. A TIFF keeps the full data a scanner or camera captured — ideal for editing and printing, wasteful for sharing. JPG, WebP, and AVIF trade a controlled, often invisible amount of quality for files 5–20× smaller, which is why they dominate the web. Converting is simply choosing the right tool for the job: TIFF to store and print, a compressed format to send and display.
Yes. Your file is uploaded over an encrypted (TLS) connection, processed on our servers, and deleted automatically after a few hours. There's no sign-up, no watermark on the output, and files are never shared or made public. In our testing, a 24-megapixel uncompressed RGB TIFF (around 72 MB) converted to a "Very High" quality JPG landed near 4–5 MB, finishing within a few seconds of the upload completing.
