Bulk Image Converter
Convert a batch of images between JPEG, PNG and WebP in one go — for example a folder of WebP downloads to JPEG, or PNG screenshots to WebP.
Result
Add images, choose a format and select Convert all.
How to use this tool
- Add up to 100 images in any common format.
- Choose the output format. For JPEG, choose the colour that replaces transparent areas.
- Select Convert all and download the files or the ZIP.
How it works
Each image is decoded by your browser, drawn onto a canvas at its original size and encoded in the new format. PNG is lossless; JPEG and WebP use the chosen quality.
Example
WebP downloads to JPEG
Ten WebP product images converted to JPEG at 90% quality keep their dimensions and can be opened by any software that does not support WebP.
Privacy and limitations
- Conversion happens on your device; nothing is uploaded.
- Converting lossy images (JPEG, WebP) to PNG does not restore lost detail and makes files larger.
- Animated images use their first frame. Metadata is not copied.
Frequently asked questions
Can I convert HEIC photos from an iPhone?
Only if your browser can open HEIC files, which most cannot yet. Set your iPhone camera to “Most Compatible” to save JPEGs, or export as JPEG first.
Will converting change the image size?
No — dimensions stay the same. Use the Bulk Image Resizer to change size.
