Is this BMP to TIFF converter really free?

Yes. Up to 5 files at a time, no signup, no catch. The free tier adds a small watermark to image output — Pro ($9.99/mo or $49/yr) removes it, raises the file size limit to 500 MB, and unlocks unlimited batch conversion.

Are my files uploaded to a server?

No — and you can verify it yourself. Open DevTools → Network tab, then convert a file. You'll see zero upload requests. Everything runs right in your browser. We never see your files.

How long does conversion take?

Usually 1–3 seconds for a typical file. The very first conversion on a fresh page load may take 5–20 seconds while the converter engine loads — after that it's instant. Your CPU does all the work locally.

What is the file size limit?

Free: up to 10 MB per file, 5 files per batch. Pro: up to 500 MB per file, unlimited batch. If you're working with large videos or RAW photos, Pro is built for that.

Can I batch convert multiple BMP files at once?

Yes — drop multiple files at once (or Ctrl/Cmd+click to select them) and they all convert in parallel. Free accounts handle up to 5 files per batch; Pro has no limit.

Will the image quality change after conversion?

It depends on the formats involved. Converting to a lossless format like PNG preserves every pixel exactly. Converting to a lossy format like JPEG or WebP applies compression — we default to 85% quality, which looks identical to the original for almost all images. You won't notice a difference unless you zoom in pixel-by-pixel.

Do you support batch image conversion?

Yes — drop multiple images at once and they all convert in parallel. Free accounts handle up to 5 at a time; Pro is unlimited. Download everything as a single ZIP when you're done.

What does TIFF offer over BMP for professional work?

TIFF supports metadata (DPI, colour profiles, creator info), multiple compression options, CMYK colour mode, and multi-page documents. BMP supports none of these, making TIFF far more versatile for professional workflows.

Is BMP to TIFF a lossless conversion?

Yes — both formats store full uncompressed pixel data. No quality is lost in the conversion; only the file container and metadata capabilities change.

How private is this converter?

Completely private — by design, not policy. There is no upload endpoint. Files are processed right inside your browser tab and disappear the moment you close it. We collect only anonymous page-view counts; your file content is never seen or stored.

BMP to TIFF Converter — Free, Online, No Upload

How to convert BMP to TIFF online

1
Drop your BMP file
Drag and drop your Bitmap Image File file onto the converter, or click to browse your files. You can select up to 5 at once. Nothing leaves your device — conversion happens right here in the browser.
2
Hit Convert — it happens locally
Click Convert and watch it go. There's no upload, no server queue, no waiting. The converter runs Bitmap Image File → Tagged Image File Format entirely in your browser tab. Most files finish in 1–3 seconds.
3
Download your TIFF
Your Tagged Image File Format file is ready. Click Download, or grab a ZIP if you converted a batch. Close the tab and everything disappears — no copies kept anywhere.

BMP vs TIFF: format overview

BMP

Bitmap Image File

Microsoft · 1987

Compression: none
Transparency: No

✓ No compression — original pixel data preserved
✓ Universal Windows support
✗ No compression = massive files

TIFF

Tagged Image File Format

Aldus Corporation · 1986

Compression: lossless
Color depth: 32-bit
Transparency: Yes

✓ Preserves maximum quality for archiving
✓ Supports multiple layers and pages

BMP magic bytes: 42 4D

TIFF magic bytes: 49 49 2A 00 (little-endian) / 4D 4D 00 2A (big-endian)

Why convert BMP to TIFF?

BMP and TIFF are both uncompressed or lightly compressed formats, but they serve different environments. BMP is the native Windows format, primarily used by Windows applications. TIFF is the professional standard used by print production, scientific imaging, document management systems, and archival workflows — and it's supported on Windows, macOS, and Linux alike.

If BMP files need to enter a print workflow, a TIFF is what InDesign, QuarkXPress, and professional print RIP software expect. Scientific labs that output image data to BMP (a common output from microscopy and industrial imaging equipment) often need to convert to TIFF before submitting images to journals or databases. Archival systems at libraries, museums, and government agencies mandate TIFF for long-term storage because of its standardization and metadata support.

Because BMP is uncompressed, the conversion to TIFF is lossless — every pixel is preserved exactly. TIFF with LZW or ZIP compression will often be smaller than the equivalent BMP, making the conversion a win both for compatibility and storage efficiency. TIFF also supports multi-page documents, 16-bit color depth, and embedded ICC color profiles — capabilities BMP lacks entirely. If you're archiving or publishing BMP images, TIFF is a strict upgrade.

Quality & file size: BMP to TIFF

Typical file sizes: BMP 35–40 MB → TIFF 20–70 MB.

Both BMP and TIFF use lossy compression. We transcode at high quality settings (equivalent to TIFF's recommended web quality) to minimize generational loss.

Color depth: BMP supports standard color, TIFF supports 32-bit.

Transparency: BMP does not support transparency. TIFF preserves transparency.

Privacy: how FormatDrop handles your files

Your BMPfiles are converted 100% inside your browser. They are never uploaded to our servers, never stored, and never seen by anyone other than you. This isn't a privacy policy claim — it's an architectural guarantee: our server has no endpoint that receives file bytes.
