About Image Converter
Upload one image and pick the format you need. JPG and WebP outputs let you set the quality, which decides the trade-off between file size and detail.
Animated GIFs are converted from their first frame. Transparency is kept for PNG, WebP and TIFF output, and filled with white for JPG, BMP and GIF.
Which image format should you choose?
| Format | Good for | Transparency | Compression |
|---|---|---|---|
| JPG | Photos for websites, email and messaging | No | Lossy, quality setting |
| PNG | Screenshots, logos, graphics with text | Yes | Lossless |
| WebP | Websites that need small, sharp images | Yes | Lossy, quality setting |
| GIF | Simple graphics with few colours | No | Lossless, 256 colours |
| BMP | Older Windows software that requires it | No | Uncompressed |
| TIFF | Print and archive workflows | Yes | Lossless |
Common conversions
- WebP to JPG: when an app, form or older editor will not open WebP files, JPG at quality 85–90 opens almost everywhere.
- PNG to WebP: for websites. Transparency is kept and files are usually much smaller than the PNG.
- TIFF to JPG: for scans and print files you want to email or upload. Expect a much smaller file.
- BMP to PNG: same pixels, lossless, and typically a fraction of the size of an uncompressed BMP.
- JPG to PNG: useful when a tool requires PNG, but it cannot bring back detail that JPG compression already removed.
Good to know
Converting from a lossless format to JPG or WebP makes the file smaller by discarding some detail. Converting the other way round keeps the image exactly as it is, but the file usually gets bigger.
The converted file contains the image only. Camera metadata such as date, device and GPS location is not copied, and photos keep their correct orientation.

Questions
Which formats can I convert between?
Any of JPG, PNG, WebP, GIF, BMP and TIFF can be converted to any other of those formats.
Is HEIC supported?
Not yet. Convert HEIC photos to JPG on your phone first, then use GlobTool for further changes.
Will I lose quality?
PNG, BMP and TIFF are lossless. JPG and WebP are lossy, so lower quality settings make smaller files with less detail. 85 is a good default.
What happens to my file?
It is processed on GlobTool's server and the result is deleted automatically after about an hour. No account is needed.
