How to convert PHOTO to JPEG
JPEG (Joint Photographic Experts Group) is the most universally supported compressed image format for photographs. Converting photos from formats like HEIC, PNG, WEBP, BMP, or TIFF to JPEG produces files that open on every device, platform, email client, and social network without compatibility issues. JPEG achieves high compression ratios for photographic content, significantly reducing file sizes while maintaining acceptable visual quality.
BoltConverter converts your photos to JPEG entirely in your browser using WebAssembly. Your images never leave your device. The converter accepts all common photo formats and produces a high-quality JPEG output at a quality level that balances file size and visual fidelity.

Photo is converted to JPEG in your browser
WebAssembly decodes your photo format and re-encodes it as a JPEG on your device, with no upload.

Frequently asked questions
Will converting to JPEG reduce image quality?
JPEG is a lossy format, so some detail is compressed away. BoltConverter uses a high-quality setting that keeps any quality reduction imperceptible for typical photographic content. Converting from a lossless format like PNG does introduce some compression.
Are my photos uploaded to the internet?
No. The conversion runs entirely in your browser using WebAssembly. Your photos never leave your device.
Will transparency be preserved in the JPEG?
No. JPEG does not support transparency. Any transparent areas in your source image (from a PNG or WebP with alpha) will be filled with a solid background color in the JPEG output.
Why are iPhone HEIC photos not opening on my Windows computer?
Windows does not natively support the HEIC format that iPhones use by default. Converting HEIC photos to JPEG makes them readable on any Windows system without installing 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.
