Free Image Format Converter: Batch Convert JPG, PNG, WebP, AVIF and TIFF
Batch convert image formats online for free with DocCrunch. Convert JPG, PNG, WebP, AVIF and TIFF locally in the browser, keep transparent PNG workflows, optimize WebP for websites and avoid unnecessary server uploads.
Different platforms prefer different image formats. Websites often benefit from WebP, design workflows may need transparent PNG, and email attachments are usually easiest as JPG. Manually exporting every file one by one wastes time.
DocCrunch Image Format Converter lets you batch convert static image formats in the browser. It is a free image format converter for JPG, PNG, WebP, AVIF and TIFF workflows.
Which Image Format Should You Choose?
| Format | Best for | DocCrunch note |
|---|---|---|
| JPG | Photos, email attachments | Good balance of size and compatibility |
| PNG | Transparency, icons, screenshots | Use for transparent backgrounds |
| WebP | Modern websites | Often smaller for web performance |
| AVIF | High compression web images | Useful when platform support is acceptable |
| GIF | Animation | Use GIF Compress, not static conversion |
Static image conversion belongs in Format Converter. Animated GIFs need their own workflow to preserve frames.

Which image formats can DocCrunch convert?
DocCrunch supports common static formats such as JPG, PNG, WebP, AVIF and TIFF. Animated GIFs should be handled with the dedicated GIF compression or crop tools.
Does JPG to PNG create transparency?
JPG files do not contain transparency. If you need a transparent PNG, remove the background first with AI background remover, then export PNG.
Does format conversion upload my image?
No. Static image conversion happens in the browser, which is useful for client assets, unpublished designs and private scans.
Can I batch convert images?
Yes. Choose multiple files, select the output format and download converted results in a batch workflow where available.
Is WebP conversion the same as compression?
No. WebP conversion changes the file format, usually for better web efficiency. Compression reduces file size within a chosen format. Web optimization often uses both.
