BMP to TIFF Converter

BMP vs TIF — Which Should You Convert To?

If you have a Windows Bitmap (.bmp) and you are wondering whether to move it to TIF, the short answer is yes for almost any archival, print, or editing purpose. Both formats are lossless, so the pixels stay byte-for-byte identical — but TIF can wrap those same pixels in LZW or Deflate compression to produce a much smaller file at zero quality cost, and it is the format that print shops, scanners, and editing pipelines actually expect. Stay on BMP only when a specific piece of legacy Windows software demands a raw bitmap.

Side-by-side Comparison

Neither format throws away image data, so this is not a quality decision — it is a decision about file size, tooling, and metadata. BMP wins on nothing here except raw simplicity and legacy Windows reach; TIF wins on compression, professional acceptance, and richer features.

When to Pick BMP

• A legacy Windows application, point-of-sale display, or embedded device reads only the raw .bmp bitmap.
• You need the absolute simplest possible raster container with no compression layer to decode.
• A tool in your chain explicitly fails on TIFF but accepts BMP.
• You are matching the input format of an old imaging SDK that predates broad TIFF support.

When to Pick TIF

• You are archiving a master copy and want a lossless file that is smaller than BMP thanks to LZW or Deflate.
• The image is headed to a print shop or desktop-publishing layout, where TIFF is the long-standing standard.
• You scanned a document or photo and want to keep CMYK or high-bit-depth color that BMP cannot reliably carry.
• You need embedded metadata — DPI, an ICC color profile, capture details — that BMP largely drops.

How to Convert BMP to TIF

1. Upload Your BMP File: Drag and drop your bitmap onto the page or click "+ Add Files" to add one or several images at once.
2. Set the Compression Type: Open Advanced Options and pick a lossless Compression Type so the conversion stays pixel-perfect. The default exposes a JPEG mode, which is lossy — leave it on a lossless option (LZW or Deflate) unless you specifically want to trade quality for a smaller file.
3. Resize if Needed (Optional): Use Image resolution — Keep original, Resolution Percentage, or Width x Height — only if you want to rescale; for an archival master, keep the original dimensions.
4. Convert and Download: Click "Convert" and download your TIF. No sign-up, no watermark. Prefer the .tiff spelling? See the twin tool, BMP to TIFF — same conversion, same bytes.

Frequently Asked Questions

Will converting BMP to TIF lose any quality?

No. BMP and TIF are both lossless, so the conversion copies every pixel across unchanged — the picture is byte-for-byte identical as long as you keep a lossless Compression Type (None, LZW, or Deflate). The only way to lose quality is to switch the Compression Type to the lossy JPEG-in-TIFF mode, which re-encodes the image to shrink it; for an archival or print master, leave that off.

Is the TIF file smaller than the original BMP?

Usually, yes, and that is the main practical reason to convert. BMP stores raw uncompressed pixels, so a 1920×1080 24-bit image lands around 6 MB. TIF can apply LZW or Deflate (ZIP) lossless compression to the exact same pixels, which commonly trims 30–60% off graphics and screenshots while keeping the image identical. Already-noisy photographs compress less; flat-color images compress more.

Which Compression Type should I choose for TIF?

For a lossless result, LZW is the long-standing default with the broadest software compatibility, and Deflate (ZIP) usually packs a little smaller. Both keep every pixel intact and differ only in file size and speed. LZW was added to the TIFF spec in 1988 and Deflate in a 2002 supplement, so very old TIFF readers occasionally prefer LZW. Avoid the lossy JPEG Compression Type unless you deliberately want a smaller, slightly degraded file.

Is a .tif file the same as a .tiff file?

Yes — .tif and .tiff are two spellings of the same Tagged Image File Format, and the bytes inside are identical. The three-letter .tif survives from MS-DOS and early Windows, which capped extensions at three characters under the 8.3 filename rule. This tool exposes a TIFF / TIF extension toggle so you can match whatever your other software expects; either choice produces the same file. The BMP to TIFF page is the same converter under the longer name.

Why not just keep the image as a BMP?

BMP's only real advantage is legacy Windows compatibility — it is a raw, uncompressed bitmap that very old tools and some embedded systems read directly. For storage, print, or archival, that uncompressed design is a liability: the files are large and BMP carries little metadata, no reliable CMYK, and no consistent transparency. Per MDN, BMP is also discouraged for the web because of its size. If you need a lossless web-friendly image instead, BMP to PNG compresses losslessly and displays in every browser, while BMP to JPG is better for sharing photos at a small size.

Can I display the TIF in a browser or on the web?

Mostly no. Per MDN, Safari is the only major browser that renders TIFF natively in web content; Chrome, Firefox, and Edge do not. TIFF is meant as a working or archival file for print and editing, not a web display format. If the image needs to show up on a page, convert to BMP to PNG for lossless graphics or BMP to JPG for photos.

Does the TIF keep transparency or CMYK that BMP could not?

The conversion can only carry forward what the source BMP contained, and a standard BMP has neither reliable alpha transparency nor CMYK. So the TIF will not gain transparency or CMYK out of thin air — but TIFF as a container does support both, which matters if you later edit the file or composite it in a print layout. In our testing, a 1920×1080 24-bit BMP of roughly 6 MB converted to an LZW TIF of about 3–4 MB with the pixels unchanged.

How are my files handled, and how long are they kept?

Your file is uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark, never shared or made public.
