How to convert to JPG
JPG is the most universally supported image format on the web, in email, and across all devices. Whether you have a PNG with a white background, a HEIC photo from an iPhone, a WEBP image from a website, a GIF, or another format that is not opening where you need it, converting to JPG produces a file that works everywhere. JPG achieves high compression for photographs while keeping file sizes manageable.
BoltConverter converts images to JPG entirely in your browser using WebAssembly. Your files never leave your device. The converter supports all major image formats as input and produces a high-quality JPG output at a balance of quality and file size.

Frequently asked questions
What image formats can be converted to JPG?
BoltConverter supports converting HEIC (iPhone photos), PNG, WEBP, GIF, BMP, TIFF, and most other common image formats to JPG.
Are my files uploaded anywhere?
No. The conversion runs entirely in your browser using WebAssembly. Your files never leave your device and are never sent to any server.
Will transparency be preserved when converting to JPG?
No. JPG does not support transparency. Transparent areas in your source image (from PNG or WebP with alpha) will be filled with a solid white background in the JPG output.
Why are my iPhone HEIC photos not opening on Windows?
Windows does not include native HEIC support. Converting your iPhone photos to JPG makes them viewable on any Windows computer without additional codecs.
Is there a file size limit?
Because conversion happens in your browser, there is no server-side limit. The practical limit is your device's available memory.
