Convert WebP to BMP

No — BMP has no alpha channel, so transparent regions are composited against a background colour, white unless you change it. That is the single most common surprise in this conversion: a logo that looked clean on a dark page arrives with a white box around it. Set the matte colour to match wherever the image will sit, or choose a target that keeps alpha. BMP is gigantic — a 12-megapixel photo is around 36 MB — and no browser treats it as a sane web format.

No. The compression artefacts already baked into the WebP are ordinary pixel data now, and BMP preserves them perfectly rather than removing them. The file usually gets larger, sometimes several times larger. It is still worth doing before editing, because further edits will not stack a second generation of loss on top. BMP needs no decoder library at all, so it remains the safe interchange format for embedded systems and legacy Windows tooling. WebP is still second-class outside the browser — print workflows, older Office builds and some phone galleries do not accept it.

By default yes, wherever the target has somewhere to put it — camera model, exposure settings, lens and GPS coordinates all carry across. GPS is the field worth thinking about: if the image is going to be published, use the strip-metadata option so you are not broadcasting where the photo was taken. WebP is Google’s 2010 image format, built from the VP8 keyframe encoder and intended to replace JPG, PNG and GIF at once.

Only the first frame survives, because BMP is a still format with nowhere to store the rest. If the animation matters, target a format that animates, or convert to a video container instead and keep the motion.

Transparency survives when going to PNG, WebP, TIFF, GIF, or SVG. Converting to JPG flattens the alpha channel against a white background — if you need transparency, target a transparency-aware format instead of BMP.

Embedded ICC color profiles are read from the source WebP and re-attached to the BMP output where the format supports it (JPG, PNG, TIFF, WebP). Formats without profile support fall back to sRGB.

Camera EXIF (ISO, shutter, lens, GPS) is preserved by default during WebP → BMP conversion when both formats support metadata. Use the privacy option to strip metadata before download if you want to share images without geolocation.

Yes — drag multiple WebP files into the upload zone and we queue them in parallel. Free users get 100MB per file; Premium has no per-file cap and runs more parallel workers, so a 200-image batch typically finishes in under two minutes.

For straightforward format conversion we run the same libpng / libjpeg-turbo / libwebp / ImageMagick pipelines a desktop editor uses, with the same quality. The difference is that desktop tools open one file at a time; we accept a batch and run them in parallel.

Default behaviour is 1:1 — your BMP output has the same pixel dimensions as the source WebP. Use a separate /resize-image/ step after conversion if you need to downscale or upscale as part of the workflow.

For JPG / WebP, quality 75-85 typically gets the file 60-80% smaller than the source WebP with no visible difference at normal viewing distance. For lossless targets (PNG, TIFF), expect smaller savings — usually 5-30% via better deflate / LZW compression.
