Is this TIFF to BMP 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 TIFF 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.

Is there any quality difference between a TIFF and a BMP of the same image?

Both store uncompressed pixel data, so the visual output is identical. The difference is container features: TIFF supports metadata, colour profiles, and CMYK; BMP does not.

My scanner produces TIFF but my software needs BMP — is this common?

Yes, particularly with older scanning or OCR software. Modern scanners default to TIFF, but legacy OCR engines (like early ABBYY or Tesseract front-ends) sometimes required BMP input.

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.

TIFF to BMP Converter — Free, Online, No Upload

How to convert TIFF to BMP online

1
Drop your TIFF file
Drag and drop your Tagged Image File Format 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 Tagged Image File Format → Bitmap Image File entirely in your browser tab. Most files finish in 1–3 seconds.
3
Download your BMP
Your Bitmap Image File file is ready. Click Download, or grab a ZIP if you converted a batch. Close the tab and everything disappears — no copies kept anywhere.

TIFF vs BMP: format overview

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
✗ Extremely large file sizes

BMP

Bitmap Image File

Microsoft · 1987

Compression: none
Transparency: No

✓ No compression — original pixel data preserved
✓ Universal Windows support

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

BMP magic bytes: 42 4D

Why convert TIFF to BMP?

TIFF is the professional archival format, but not every application can read it. Older Windows software, legacy industrial tools, and some embedded systems that understand BMP natively but have no TIFF library will fail to open a TIFF file. Converting to BMP makes the image readable by any Windows application ever written.

BMP is Windows' built-in uncompressed image format, and it's been part of the OS since version 1.0. Paint opens it. Older VB6 and Delphi applications handle it natively. Some label printers, CNC controllers, and machine vision systems require BMP because their embedded image decoders only handle uncompressed Windows bitmap data. If TIFF is being rejected by a legacy tool, BMP is the reliable fallback.

Both BMP and TIFF can be lossless formats, so the conversion doesn't degrade image quality — every pixel is preserved. File sizes for BMP will be similar to or slightly larger than uncompressed TIFF, since BMP has no compression option in its basic form. If the source TIFF uses LZW or ZIP compression, the BMP will actually be larger than the TIFF. TIFF features like layers, multi-page support, and embedded ICC color profiles are not carried over to BMP — you get a flat, single-page, uncompressed image. For 16-bit TIFF sources, BMP will represent the image in 24-bit (8 bits per channel), so high bit depth is lost.

Quality & file size: TIFF to BMP

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

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

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

Transparency: TIFF supports transparency. BMP does not support transparency — transparent areas become solid white.

Privacy: how FormatDrop handles your files

Your TIFFfiles 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.
