Image format converter.
Convert images between JPG, PNG, WebP, GIF, and BMP. Batch up to 10 files. Everything runs locally in your browser: no uploads.
How to convert image formats
- Choose up to ten images in JPG, PNG, WebP, GIF or BMP.
- Pick the output format: JPG, PNG or WebP.
- For JPG and WebP, set the quality. Between 80 and 90 is the sweet spot for web use.
- Press Convert image(s) and download each result.
Which format should you pick?
Use JPG for photographs, where small files matter more than perfect pixels. Use PNG for logos, screenshots and graphics that need sharp edges or transparency. Use WebP when you want the smallest files for a website and your audience uses current browsers. If you are sending an image to someone else, JPG and PNG are the safest bets because everything opens them.
Converting from a lossy format to another lossy format loses a little more quality each time, so convert from the best source you have, not from a copy that has already been compressed.
Converted on your device
Each file is decoded and written out by your own browser inside an isolated frame with no network access. Nothing is uploaded, nothing is stored on a server, and the advertising on this page cannot see your images.
Notes
- GIF animations become a single frame.
- Transparency is lost when converting to JPG; a background colour is used instead.
- Metadata such as EXIF and GPS is not copied into the converted files.
Understanding image formats
Choosing the right image format affects file size, quality, and compatibility. This converter does everything locally in your browser: your images never leave your computer.

Quality slider
90–100%: archival / print. 80–89%: sweet spot for web. 70–79%: thumbnails. Below 70% becomes visibly degraded on most photos.
