Lower resolutions reduce file size. The video will not be enlarged.

Bitrate

Higher means better sound and a larger file. “Auto” keeps the bitrate of the original (at least 128 kbit/s); from lossless files it uses the format’s high-quality setting.

Pages to convert

Several pages arrive as a ZIP with one image per page.

Shown by e-readers in the library; leave empty to keep what the document says.

PDF/A-2b embeds all fonts so the file looks the same in many years; required by many courts and public offices.

Scales every sheet so it fits on a single page instead of being split across several.

Sheets

CSV and TSV hold one table: with “Every sheet” each sheet becomes its own file, together in a ZIP.

Separator

Excel in many European languages expects a semicolon; most other programs a comma.

Convert on our server?

If you continue, the file is uploaded over an encrypted connection and converted on our server. You can keep using the site meanwhile. The original is deleted as soon as it is converted; the result is kept for 7 days so you can download it, and you can delete it at any time. Files are never shared or used for anything else.

Your images are processed in your browser and are not uploaded. If a file is too large for your browser or in a format it can’t handle, we ask before converting it on our server. The original is deleted right after conversion; the result is kept for 7 days for you to download, unless you delete it sooner. Privacy details

How to use: WebP to BMP

  1. 1 Choose or drag in one or more WebP files.
  2. 2 Pick a background colour for transparent areas, because BMP has no transparency.
  3. 3 Click Convert. The gear button next to a file opens its options; files you add afterwards are converted straight away.
  4. 4 Download the BMP files one by one, or all at once as a ZIP file.

About this tool

WebP is a modern web format from Google. It makes files much smaller than JPG or PNG at similar quality and supports transparency. BMP is an uncompressed Windows bitmap format: simple and widely readable, but files are large.

Converting to BMP is useful for older Windows programs, embedded devices and software that only reads BMP. Animated files are converted using their first frame. BMP has no transparency, so transparent areas are filled with the background colour you choose (white by default). BMP files are uncompressed or lightly compressed, so expect them to be much larger than the WebP.

Files are converted in your browser and are not uploaded to a server. If a file is too large for your device, the tool explains why and asks before sending it anywhere. Hidden metadata such as the GPS location is not copied into the BMP.

Frequently asked questions

Are my files uploaded to a server?

No. The conversion runs in your own browser, so your files stay on your device. Only if a file is too large for your browser does the tool offer server processing, and it asks you first.

Will converting to BMP improve the quality?

No. BMP stores the pixels exactly, so no further quality is lost from now on, but it cannot restore detail that the WebP compression already removed.

What happens to transparent areas?

BMP doesn't support transparency. Transparent areas are filled with the background colour you choose, white by default. Convert to PNG, WebP or AVIF if you need to keep transparency.

Why is the BMP file so much bigger?

BMP stores images with little or no compression. That keeps full quality and makes the file easy to read for other programs, but the file is often many times larger than the WebP.

Are animations kept?

No. Animated WebP files are converted using their first frame, so the BMP is a still image.

Is the image's metadata kept?

No. The BMP is created from the image pixels only, so EXIF data such as the GPS location, camera model and capture time is not copied. This is useful before sharing images online.
