Convert HEIC to JPG Free — No Upload, Works In Your Browser

1. 1Add your HEIC photosDrag .heic files onto the drop zone, or select them with the Choose photos button. You can add several at once.
2. 2Pick a format and qualityChoose JPG for the widest compatibility, or PNG if you need lossless output. Set JPG quality between 60% and 100%.
3. 3Convert and downloadSelect Convert to JPG, then download each photo individually or all of them together as a ZIP file.

HEIC is Apple's container for the HEIF image format, and it has been the default camera format on iPhone since iOS 11 shipped in 2017. It stores the same photo in roughly half the space of an equivalent JPG because it uses HEVC compression instead of the much older JPEG algorithm.

The saving comes at the cost of compatibility. Windows requires a paid codec from the Microsoft Store to preview HEIC files in Photos, many Android phones cannot open them at all, and a large share of websites, forums and job-application portals reject the extension outright. Converting to JPG solves all three problems at once.

JPG is readable by effectively every operating system, browser, photo editor and upload form written in the last thirty years. Converting is the fastest way to attach an iPhone photo to an email, upload it to a government or university portal, print it at a photo kiosk, or share it with someone on Windows or Android.

The tradeoff is file size: because JPEG compression is less efficient than HEVC, a converted JPG is typically larger than the HEIC it came from. Lowering the quality slider brings the size back down, and PNG output is available when you need lossless pixels for editing rather than a small file.

Decoding happens locally through a WebAssembly build of libheif, the same open-source library used by GIMP and ImageMagick. The files are read into browser memory, converted with a canvas, and offered back as a download. No photo is sent to a server, which means nothing to breach, nothing retained after you close the tab, and no upload wait even for large batches. It also means the tool keeps working with the network disconnected once the page has loaded.

The quality slider controls JPEG compression only and has no effect on PNG output. At 100% the encoder preserves the most detail and produces the largest file. At 85%, the default here, compression artefacts are difficult to see on a photograph at normal viewing size while the file is substantially smaller. Below about 60%, blocking becomes visible in skies, skin tones and other smooth gradients. Because JPEG is lossy, re-saving a converted JPG degrades it further: convert from the original HEIC, not an earlier export.
