Is this BMP to GIF 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.

Why would I want BMP as a GIF?

GIF is required by some older platforms, email clients, and tools. If you have a BMP graphic — especially a flat-colour logo or diagram — converting to GIF produces a small, compatible file.

Will a photographic BMP look bad as a GIF?

Yes — GIF is limited to 256 colours, so photographs with gradients will show colour banding. GIF works best for simple graphics. For photos, convert to JPG or WebP instead.

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.

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 → Graphics Interchange Format entirely in your browser tab. Most files finish in 1–3 seconds.
3

Why convert BMP to GIF?

BMP files are uncompressed, high-color images — they store every pixel in full color depth, which makes them large but faithful. GIF is the opposite: compressed, 256-color, designed for simple graphics. Converting BMP to GIF intentionally trades color depth and file accuracy for a widely compatible legacy format.

The reason you'd convert BMP to GIF is usually platform compatibility. Old web systems, certain email clients, legacy content management tools, and some embedded display systems only accept GIF. If the BMP contains a simple graphic — a logo, an icon, a diagram with few colors — the 256-color limit of GIF may not be a visible problem. If the BMP is a photograph or gradient-heavy image, the color reduction will produce visible banding and dithering.

GIF's LZW compression actually makes it much smaller than BMP for simple graphics. A 5 MB BMP logo with flat colors might become a 50 KB GIF. For photographic BMPs, the result is less predictable — GIF may actually be larger than a JPEG of the same image because the forced 256-color palette requires more data to represent complex scenes via dithering. Only convert to GIF when the target platform specifically requires it; for web use, PNG or WebP handle everything GIF does with better quality and smaller files.

Quality & file size: BMP to GIF

Typical file sizes: BMP 35–40 MB → GIF 1–5 MB.

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

Color depth: BMP supports standard color, GIF supports 8-bit.

Transparency: BMP does not support transparency. GIF 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.
